Always check for coolant flow through the bypass pipe that goes over the top of the engine to the coolant reservoir. There should be a constant flow. If there is not, you need to clear it out. They get plugged up where it attached to the water pump housing. Also chech the "hollow bolt" that it attached to. Mine was plugged. This WILL cause overheating.
I still think it is crazy that they stuck a northstar in an "old person" car. The DTS scoots. It is a smooth running, great sounding, sophisticated V8 that was originally designed for racing. I love my 2008. I want another one, but the performance or platinum version. I have a luxury 3.
From what I’ve read by 2006 the North Star engine got upgraded head bolts and the head gasket failure issue was solved. Obviously the early North Star motors up to the early 2000s were prone to head gasket failure from what I read 2006-2011 are not prone and only way to have head gasket failure is if you ignore a water pump leak or the common plastic t and hoses on the top back side of motor and the car overheats. Also never use green antifreeze that will cause issues
You can use any kind of coolant you want as long as you make sure to flush it completely first! Don't be a jackass and mix "the green" with the evil dex cool unless you want a gummy mess. My suggestion --get rid of that dex cool crap on ANY and EVERY vehicle ASAP!
some people convert them because they still think dex cool is a bad coolant. It isn't, and it is what GM uses in all there vehicles. They changed the formula some time ago.
hey marty, would you happen to know if the cadillac is still running right ? going to try blue devil soon.. i am actually in the middle of doing my head gaskets but taking a look at removing the timing chains i’ve decided it’s too much for me to tackle. thank you sir!
Hi Herkylo yes it’s still running good just seen it a week ago was talking to the lady . I bought mine at O’Reillys parts the guy there said it had a money back guarantee . I tried it on a Toyota and it didn’t work on that car the guy gave me my money back but I also know the guy well . Just ask about the guarantee . Some will hook you up some Wont there was another guy there that said no to me ???? Check out the video on my channel
Great video Marty, although need clarification. I've always seen info stating to install the thermostat with the vent facing upwards but you installed it towards the bottom, so which one is the correct procedure? Thanks again
Hi Shanehall yes I would put it to the top my bad I just stuck it back the way I took it off but preferably on the top. Thanks for watching. I appreciate you.
Hey Marty, could you notice any obvious symptoms of a blown head gasket with that car before you sealed it? Was it smoking? Running rough? Untraceable coolant loss/milky oil?
Hi Demps Giles no nothing noticeable it would just get hot no smoke no leaks it would just get hot and it would be low on coolant and like I mentioned she had already taken the car to another mechanic and the mechanic said it had a blown head gasket but she didn’t believe that Mechanic so I went to Harbor freight and bought that kit to check for blown head gasket and it confirmed it and after I use that sealant, it’s been working good since then thanks for watching. I really appreciate you.
My 08 DTS keeps overheating and consuming all the coolant could the thermostat be the problem my fans work , water pump works gonna change it out today and see what happens
Hi 448raf I hope it’s just thermostat but try bleeding the system burping it even flushed the heater core maybe plugged up. and do a combustion check on the radiator. They sell the kit at Harbor freight tools to see if you have a blown head gasket. Hope everything works out brother and thank you for watching my videos. I really appreciate you.
Hey Marty... you should only use that blue stuff if you are planning on getting rid of the car.... would not use that if you are planning on keeping the car... yes it will close up the crack.. but...it will get into other areas internally.. like the radiator and cause other problems... dont use this if you plan on keeping your caddi...just a thought...
Hi Robert Buford if it comes out of the back of the motor its probably cracked head or blown head gasket. if more to the front maybe water pump hope that helps you thank you for watching i appreciate you
Hi Bennie McaDoo most vehicles have a drain plug on the button of the radiator on left or right side if your vehicle don’t have one just unplug the lower radiator hose and drain it out that way. Hope that helps you and thank you for watching. I really appreciate you.
They did, better head studs etc. But if running while over heated like she probably did them you can still cause a prob with head gasket no matter the car/model. And in time the gasket itself can fail, it was just very common on pre 2005 model Cadillacs because of the bolts themselves
Hey Marty i noticed texas tags. I have a 2010 dts exactly the same color as the one in this video. If you are in the Dallas area I'd love for you to do some work on mine if possible. Email me if possible
@@Marty09933 i appreciate your videos brother. Was having same problem. One day it ran so hot i cant believe it didn't blow head gaskets. I lost most coolant and replaced it without further coolant loss. Ran fine for 2 weeks now started to run hot again. No coolant loss. 1 year ago i had new water pump, belt and thermostat and since no coolant loss has occurred and everything else is good,i am going to replace thermostat again due to Suspicion it may have been faulty or damaged by running it hot that day. If that doesn't work I'll let a professional check it out. Thanks for your info. Very helpful
Hi @@billow757 yes jack it up from the front or put it on ramps as long as the front end is higher to allow the air pockets to come up let gravity do the work and get all the air pockets out of the system hope that explains it brother and thank you for watching. I really appreciate you.

Hi arturorubio thank you and thank you for watching a really appreciate you
These things never take green antifreeze, can almost guarantee that aided the issue

I thought the 06+ models didnt have the head gaskets problems no more
Hi Daquon Fields I'm not to familiar the Cadillacs history i wouldn't know sorry brother and thank you for watching i really appreciate you
They don't, unless they overheat. But if any engine overheats, it will suffer.

Small socket with extension always helps those type of hose clamps too. That flat head screw driver always frustrates me.. lol

That thermostat has been replaced before, the design doesn’t look like the OEM
My head hurts when I see not dexcool come out of a northstar
Hi Kygaah right lol 😂 thank you for watching. I really appreciate you.
I have a 2008 Cadillac DTS as soon as I put water in it it runs out the back what caused

Heater core hoses, your welcome
Mine was heater core hose
How do I drain the water coolant on a 2006 Cadillac DTS?
Does anyone know how to do this or is UTUBE full’ a shit….after l was forced to subscribe!

I thought Cadillac resolved the head gasket issue on the 06 and up northstars

@@Marty09933 no problem boss. I know Cadillacs and basics a decent bit. Just trying to help
@@KlNGME very helpful that will help some people 👍
Dowse The vent goes toward the bottom oil pan/ground?
I have the same car n need help with it
Hi xJayxCrazy what's going on ?
It starts but I think it needs a lifter if I'm saying it right
@@xjayxcrazy9279 well thats going to need to be repaired you’ll have to look for someone that can repair that lifter sorry brother
What seal did you use?
Hi Ssgtrayle not sure what you mean. I didn’t use no seal on the thermostat and to seal the head gasket I use blue devil sealer.
Hey Marty i noticed texas tags. I have a 2010 dts exactly the same color as the one in this video. If you are in the Dallas area I'd love for you to do some work on mine if possible. Email me if possible

Is it still working
Hi James, white yes sir the customer is still driving around in it thank you for watching i appricate you
@@Marty09933 what you mean lift car to bleed?
Work on mind tomorrow
Hi @@billow757 yes jack it up from the front or put it on ramps as long as the front end is higher to allow the air pockets to come up let gravity do the work and get all the air pockets out of the system hope that explains it brother and thank you for watching. I really appreciate you.
It's overheating because you got the wrong fluid and you got to put the DEX -COOL ORANGE fluid what the vehicle recommends it's a aluminum. NOT GREEN
I thought it had a blown head gasket?
Hi Richard Fernandez yes it did have a blown head gasket but that product seal it up .that’s the third time I’ve seal a head gas using that product .
