Thanks for the video and may I add just a small tip to ensure you and your viewers don't have a problem. Always cover the inlet manifolds after removing the plenum chamber so that nothing foreign or rubber falls into a port and jams under a valve. Worst still...a clip, or nut or stone falls into the chamber and gets crushed by the piston or bends a valve etc etc. Good practice is best.
Hey mate, Thank you so much for this video! I've got the exact same problem and have had 2 mechanics tell me they can't find the problem. I finally found where the leaking was and it's exactly as you've described here. Thanks again
Well done champ, home made air pressure test for coolant leaks, now you should make a part number for it, patent it and make them yourself and work out the best and cheapest company to put them in a package with tags and sell them, to all mechanical and radiator service centres etc. :)
Jim Rodgers thanks for the kind words, most of the time the leak is here, sometimes it's at the back of the engine and that sucks. Good luck with it though, let me know how you go.
Hey mate nice vid, just a tip next time you need to do it, you don’t need to take the manifold off you can slightly loosen the bolts and raise it enough to get into the inlet pipe bolts, You also should not put oil on coolant seals, vaseline is the better option for this application 👍🏻
Thanks heaps. After creating this and seeing a few comments I read best to use silicone or teflon on rubber seals. I guess I just never had any vehicle long enough to ever see the negative affects
I appreciate the video bro very informative and you've saved me alot of time. When refilling the coolant system is there a specific way to bleed it? I've been told the alloytechs can be abit of pain for this? Cheers!
Hey I have the same car but have any issue with my steering. It’s stiff and I checked the power steering reservoir and it’s full. Not sure if I should change the fluid pump?
I have the same issue but not entirely sure if it’s the pump or water inlet gasket seal, I’ve changed the pump 2 times over 3 years. Haven’t got s compression tester. Is there another water to isolate the issue? Thanks in advance
Yeah it took longer than I thought but got there in the end :) I keep having issues with radiator caps not sealing and allowing water to go back to the overflow with hardly any pressure. I replaced the original one with an aftermarket one and it held pressure for only 1 week, ordered a genuine now one so hopefully that will seal properly!
Outstanding!, that's really good news. I hope a genuine radiator cap fixes the problem, fingers crossed. Try running some 'scotch brite' around the inside where the rubber seals slide on the aluminium, and this is where I would run a little oil to help the seals slide in and create a smooth clean seal.
Cheers man, yeah I replaced the cap with a genuine one. The new cap seals perfect :) I always find Tridon stuff is pretty crap and always fails quickly even on other cars.
Good video bro i got a similar leak on my ve,i park my car on my driveway which is a bit of an incline and cant find leak on front of engine until i had a look on transmission bellhousing and can see the pink coolant stains running down housing.I hope thats what it is the o rings and not the Welsh plugs that someone mentioned. By the way nice t shirt.rx4.
Thanks mate, remembering that the thermostat is located on the back of the engine please make sure that is it not leaking causing coolant to appear on the box. Cheers for the comment on my tshirt I will have a video of the rx4 up soon, bit of a sad one. I am currently making some new shirts that I have just finished designs for.
I just had the O ring under the inlet manifold replaced on my VE V6 in January. Was having overheating issues because stupid me didn’t realise just how low my coolant was. It would have been a slow leak overtime, but I didn’t check the coolant levels as often as I should have. I was freaking out when one day, driving for about half an hour and a half, and the temp gauge shot up almost into the red, the dropped down again, but I just kept doing that over and over. I thought it might have bin the thermostat, but the mechanic said it was an O ring not sealing properly. I have noticed since I have had this issue, the normal running temperature is just slightly higher than I remember, but it seems to be holding pressure and haven’t had any issues since.
Throttle Control I don’t have a reading, but I know at the time when having the issues that the car was starting to overheat. One hot day I was driving the car on a short trip and was inching down a busy road, and I noticed that the temp gauge was starting to rise which isn’t normal. When I got to where I was going, I turned off the car and the thermo fans continued to run after the car was turned off. That’s a sure sign that the car was starting to overheat. Turned out that I was low on coolant which explains the leak in the O ring.
Or have a small pot of hot water, not to hot, but around 40 degrees C and put them in and then they will turn soft and pliable to put over what ever they go on, cheers :)
well done buddy. very cool. i would never had thought of the simple pressure test tool cheers . might be time to invest in a new pair of gloves. seriously good on you for sharing some knowledge.
Excellent job. Congratulations. What is the direction of the water flow? Is this place you changed the oring is the water inlet of the engine or the water outlet of the engine? Thank you!
The top of the engine is usually an engine outlet, cold water falls and hot water rises, so the cold water will enter the engine at the bottom usually and work its way through until its hot and at the top and into the top of the radiator to be cooled again.
@@jacobsr20det Okay, thank you very much, I understand the operation. Is your motorcycle alloytec the thermostatic valve behind or behind the engine? If this behind the engine near the wall fires, why would holden did this? Thank you.
@@hiuri8308 yes the thermostat is at the back of the engine because holden are bastards. Everyone knows a thermostat is a replacement part and usually needed to get to.
@@jacobsr20det I heard this engine was from another front wheel drive GM or Opel or something and designed to fit east west, rather than Commodore North south rear wheel drive layout.
enedi fanovaha yes, just remove it clean the contact and ad new sealant, but for a $40 part its worth replacing the pump with a new one at the same time.
Great video. Just out of curiosity what oil did you rub inside the inlets? Is it WD40 or some specific? Also, is coolant change required when replace the seals? Yeah having same issue with bit of a coolant leak straight out to brive belt and it makes a squeaky sound. Cheers
Thanks mate, i just rubbed regular 10w40 engine oil (only a drop), I use it so the new seals don't grip the edge of the clean aluminium causing them to roll and possibly not seat correctly. You should replace the coolant at the same time (I did off camera) as this had been leaking for a while before the owner of the vehicle brought it to me so their was not much coolant left. Sounds like you are leaking from the same area, let me know how you go.
Thank you for response. I have never done this kind of work before apart from replacing a punctured wheel :). Correct me If I am wrong. ..1. Flush coolant while engine is turned of. 2. Remove manifold and remove water inlet gasket. 3. Replace seal and put everything back. 4. Top up with coolant 50/50 concentrate while engine is running..👍👍👍
you are welcome. yes you pretty much have everything under control, just the coolant it will say on the coolant bottle how to mix it, also once everything is done try to flush the system with a hose before adding new coolant. Let me know how you go :)
Hello couldnt come back earlier. I have done the replacement of the seals and changed coolant. There is no leak anymore but now have noticed that radiator hose has bit of a pink crust built up on the edges. What could be a issue?
hem08 the issue sounds like old Coolant that has leaked out. I'm sure it's not a problem, I would clean it and just keep an eye on it and make sure you don't start to see more. Well done btw
Hey man great video. I have some leaking on my VE and now I see why the mechanic quoted a fair bit for just replacing the housing on the thermostat. I heard Holden spent a billion in R&D for this car in attempt to keep us onshore - you think they might have been able to make repairs a bit easier without having those bolts all the way in the back - guess we all need a sidchrome twisty handle ratchet :)
Henry V first of all thanks. You can get away with not having a twist handle ratchet, I to be honest couldn't find my normal one. Give it a go doing it yourself.
Throttle Control no worries! I would need to get much better knowledge than what I have bro it's got dual climate and 1 side drivers the heater stoped working this cracked thermostat housing is not easy to get to - so think she's off to mechanic again already...unless uno a video that shows the engine out and following on from the manifold? It's a lot to learn!
Thanks mate. My 2009 Is currently doing something very similar after it overheated due to a faulty radiator cap. Looks like the radiator cap may of started a chain reaction :-(
nothing wrong with mine but i wanted to see how its done take that cover off also u need more videos on ve commodore timing chain i seen how about anything else be great u video good except sometimes to fast
Cringing every time he puts oil on seals for a water based system, you should always lubricate the seals with what it's used for so for a cooling system it should be lubricated with coolant. And for seals in an oil system should be lubricated with oil

Thanks Mate. I have the exact same problem. Your video helped me enormously.
Wow what a great idea
Well done mate easy way to check for leaks
Awesome 💯😎
Hey mate,

Any idea on part number ?

Hey mate thank you for the video your explanation and work is so accurate and to the point keep it up you are a great mechanic many thanks ,,,
Thanks TC. I have just bought an Omega Wagon and have a small water leak but just not sure where yet. Great idea with the pressure DIY. Thanks
Jim Rodgers thanks for the kind words, most of the time the leak is here, sometimes it's at the back of the engine and that sucks. Good luck with it though, let me know how you go.
Great job mate 👍 I also used oil a few times to lube o-rings now I use rubber grease and when i can't find my rubber grease I use oil 😅
Thanks bro found my leak with the home made pressure tester
Saved me hundreds, thanks a lot
Great vid mate👍

Cheers man I got this issue happening on my VF 3.6 SIDI. The VF has a plastic plenum and it looks easier to take off, not as many fasteners.
Thanks, its a pretty easy job, let me know how you go.

That's really good. I can agree with cheap aftermarket parts.
good time to replace spark plugs/ coils and thermostat for pre-tentative measures
Good video bro i got a similar leak on my ve,i park my car on my driveway which is a bit of an incline and cant find leak on front of engine until i had a look on transmission bellhousing and can see the pink coolant stains running down housing.I hope thats what it is the o rings and not the Welsh plugs that someone mentioned.

Do you have an actual temperature reading? Stock gauges in cars are not really accurate
Throttle Control I don’t have a reading, but I know at the time when having the issues that the car was starting to overheat. One hot day I was driving the car on a short trip and was inching down a busy road, and I noticed that the temp gauge was starting to rise which isn’t normal.

Turned out that I was low on coolant which explains the leak in the O ring.
Well done champ, if you're not already, I'm sure you'd make a brilliant mechanic.Take care :)
I normally use tyre lube or soapy water to lube the seal, don't really want put oil on rubber.
The oil is a good idea done it all the time when putting gasket on
Or have a small pot of hot water, not to hot, but around 40 degrees C and put them in and then they will turn soft and pliable to put over what ever they go on, cheers :)

I a problem with my Commodore water pump leaking not major
Hey if my Commodore water pump leaking can i reseal it
enedi fanovaha yes, just remove it clean the contact and ad new sealant, but for a $40 part its worth replacing the pump with a new one at the same time.

Henry V pain in the butt to get to the thermostat on these engines!. If not confident I would send it to the mechanic

why is this lip sinked
Cringing every time he puts oil on seals for a water based system, you should always lubricate the seals with what it's used for so for a cooling system it should be lubricated with coolant. And for seals in an oil system should be lubricated with oil
Not always. You don't lubricate brake caliper rubbers with brake fluid, you use something like Bosch rubber grease.
Vaso is best to lube rubber .
Vasoline is petroleum based and will degrade the rubber over time. Use a silicone based grease such as Herschell Silicone Paste.
Arrrgh!
Oil on O-rings!
Verboten. Use Rubber Grease.
Most oils make rubber deteriorate.
