The upgraded pump is doing EXACTLY what it's supposed to do. It transfers heat from the engine faster.
Tha makes sense, if the engine is generating the same heat but the radiator is hotter than before it is because the new water pump is more efective extracting the hot from the engine and moving it to the radiator.
Amazingly well structured clip. Liked how you in detail explained every step-by-step. Congratulations!
P.S. Definitely looking forward to seeing the long-term review of this kit.
Thank you very much! Yes I am also looking forward for some long Term Review, just keep in Mind that you maybe trade some Degree less for the Risk of two leaking Gaskets… I am still not convinced of this Pump right now.
Eventually new content. Thanks for sharing, we need the camera for our next trip to the netherlands.
Fingers crossed!
The radiator is supposed to get hotter as more heat is leaving the engine.
Mate even though the upgrade didn’t work you’ve saved a lot of people a lot of time. Well done and good luck. From Australia
Thank you very much! In some upcoming video I compared some stock Husky with my modded one. I can already tell there is some difference ;)
Thank you for everything. I'll try it. And l will write my opinion..
Thanks for your kind Comment, I appreciate that
Congratulations, very interesting videos. I have one question about the oil cooler Im planning to install too, are you happy with that? Do you think it helps to have oil working in better temperature? Thanks for your help
Thank you! To be fair I dont think the Oil Filter Cooling Cover will decrease the Temperature significantly. At least I did not recognize anything, but I also dont have some Oil Temperature Indication (yet) so this is just my Guess. At least it wont make it worse ;)
Thanks for the detailed info. Disappointed about the results as well. What about temperature of the coolant, it gets hot when riding low speed with low rpm so what is my experience: I use two sets of wheels, one is original one and the other is SMCR size. And I use the original set(enduro one) of sprockets with both sets of wheels. So because of the difference of rear wheel sizes I ride at little higher rpm with supermoto set. So the bike feels better at 1 and 2 gears at low speed and I notice that it gets hotter a little bit later in this mode. Anyway this is only my feelings)
P s. Are you using swing arm protectors from exs models? Thanks!
Unfortunately I cant change my Rear Rim Size going Offroad :D But thanks for this Information anyway, every Idea is welcome. I Just returned from some Enduro Event, we also had some stock 701 and 32 Degree Celsius Ambient Temperature. On the Stock 701 sometimes the Coolant Light turned on, but not on mine, so I guess the bigger Waterpump and Radiator Fan are doing some better Job at least.
Yea. Off course it works! And I wasn’t telling about rim change, just changing sprockets will give some improvements in speed/rpm ratio. Also I think the factory ratio isn’t the best) i would change it in any direction so will not being on very high rpm on 1st and too slow on 2nd)) cheers!!
Anyway what about swing arm protection you use?
@@user-df1ss4qg7u Thanks, I misunderstood your Point! The Protection is from Dowatek for some FE 300 if I remember it correctly, doesnt fit directly, you still have to cut out some Pieces but nothing special
Have you tried Motul Mocool coolant additive..? They claim that it lowers the coolant temperature by 15 degrees celsius. Would be nice to see you test it with the camera too :-)
No, I have not tried it yet because of following Reason: The Product claims to increase the Heat Exchange, this works in both Ways, better Heat Transfer from the Motor to Coolant and better Heat Transfer from Coolant to Radiator/Ambient. In my Opinion its good if you ride fast and as long as you have some proper Airflow to your Radiator. But if you ride slow Pace through the Woods and you wont have some proper Airflow it means that the Water will still take more Heat from the Motor but cant transfer it to the Ambient, the Result could be an even higher Coolant Temperature as before…
Hi,
Your engine side protector... What is it, manufacturer? Can you post some more details on that topic?
Best regards, Max
These are from R&G. I already drilled some Holes inside for some better Ventilation. These are hard Plastic and not Carbon. I also took the Temperature of the Cover and the original Casing with the Thermal Camera: The Temperature Difference has been 25C! These Covers insulate the Heat a lot, thinking about removing them.
Did you do any fuel mods? Like a PC5? the bike needs it because the lean running makes it run hot. With just a fuel dongle it will run hot. My 701 rally with proper fueling has no issues with overheating. Also I think adding a berotec temp guage would work well to monitor engine temp.
Nope, I did not do any Fuel Mod. Its an Euro 4 Bike, the AFR still looks good on these Bikes, Euro 5 looks much worse. Talked to a Guy today that has been with some Friends and 3 KTM 690 in Morocco. His Fan was constantly running and his Friends Coolant Light was constantly on… I wonder why there are no aftermarket Radiators or second Fans for these Bikes.
@@Speelbird Put it a Rapid Bike ECU to modify the AFR, much beter than the PC, not only the bike will run coller it will run much better on terms of throtle response. You could try to put an additional fan but you will need to move the ABS pump, and this is dificult
@@BrainOnFire Did you remove the ABS Pump?
@Speelbird No I did not. I have a 690 2023 with stock muffler, twin air filter and fuel dongle, no heat issues for now.
@@BrainOnFire I want to remove the ABS Block because of other Reasons, but I have to make myself some Plan first :)
I got a just a touch confused. You used the two supplied .5mm gaskets or two 1mm gaskets? The thicker versions would leave a gap at the end of the impeller and reduce efficiency.
The provided Gaskets looked pretty cheap and I did not like to risk some Leakage so I used the original Waterpump Casing Gaskets from KTM. Yes they are thicker as the ones that came with the Pump, they are 1mm each instead of 0,5mm. So the Gap between the Casing and Pump is bigger. If it has some bigger Effect on the Pump Efficiency I cant tell, but a bigger Gap wont make it better at all thats right.
Ambro racing do oversize waterpump kits for 690/ 701 and other big ktms and they are proven
Hey, nice video. Have you considered that the protective side cover can insulate the motor. It would be interesting to see if there is a difference with them on and off the bike.
Thank you. I just uploaded the Thermal Images of the Covers onto my Insta Account. You can check them there.
@@snyggstuffe search on Insta for d_schiho, you will find them then
Hi,
I changed the fan switch. I'm using an FAE 36500 switch who gets on at 98°C (instead of 102°C for the original one).
The engine doesn't get so hot, and the oil is cooler too.
Before, the engine oil was 130°C by hot days. Now, temp never exceeds 107°C
The limit is the fan who gets very often on.
So I bought an LR fan and housing. I hope it will solve that issue.
Thanks for your Comment! :) Please check out my latest Video to find my Thoughts about the Fan of the LR. By the Way, the Fan seems to be switched on at 120 Degree Celsius with the Stock Thermoswitch. Maybe I will purchase another Switch as you did with a lower Temperature as well.
@@Speelbird I saw your last video and did the same as you: buy a SPAL fan instead of the Husky fan. My hope is the fan will cool the water faster than the original.
Thanks to your video, I saw that the LR mount is probably not the best option.
I'll see if I can mix both mount, and keep the old one to have a bigger contact surface. I let you know if I can do that.
@@lepouzal2475 I also thought about combining the Stock Bracket with the new Fan to get the best Result. But I am on Vacation first, if you manage to combine the old Bracket with the new Fan please let me know! I think with some Multitool it should be possible but i am not sure if it will fit behind the Radiator then, maybe you can figure it out ;)
@@Speelbird I managed to install the SPAL fan on the "normal" mount. It's not well done nor good looking, but at least it's in place.
The fan is way more quiet than the original one. It gets off a bit faster. So I guess, it's cooling faster.
My Bosch thermal camera doesn't show the radiator surface like your Fluke. So I don't know if it's really working 😕
@@lepouzal2475 Nice! I guess I have to do the same then :) It doesnt matter to me if it is good looking, it should just work fine. Do you have some Pictures of it that you could send to me on Insta?
If you install the gaskets 0.5 mm?
I dont trust them, I dont like to lose Cooling Water
Mate its better or worse install this ? Sorry but i dont understand much english
Slightly better, dont expect too much
@@Speelbird better than nothing i think so. Thanks a lot mate ✌🤙
I think you misinterpreted your test results. The new water pump worked as designed, it transferred more coolant through the radiator, I.e. out of the engine. In normal conditions (like you thought too) the air flow through radiator will be able to cool the coolant more because there is a larger volume of coolant moving through the system.
Another, related mod I’ve done on my 690 is upgrade to the 701 LR fan. This is a plug & play upgrade and also helps with cooling in both stationary and slow speed situations.
Thank you for that Information. I agree, the Pump will increase the Flow and will increase the Heat that can be „transported“ by the Coolant from the Engine to the Radiator. Still, if the Heat cant be transfered from the Radiator to the Air (due to slow Riding) the Pump has no Effect. Thats the Reason why the Radiator is the limiting Part of the Cooling Circuit. So the Radiator must be bigger or must be cooled more actively as you say with a bigger Fan (LR 701 Fan). Do you use Instagram? If yes let me know because I would like to get some more Information about how you installed the bigger Fan. Thank you. :)
Hi James, I have just ordered an LR fan with the mounting frame and am waiting on them to arrive before installing. However I am curious about the screws, did you use the screws from the OEM fan or did you have to purchase other screws ? Thanks 😊
@@acp2446 Hey, could you please tell us the two Item Numbers from KTM that you ordered? And please let us also know if it will fit on the Stock Radiator of the 701 Enduro when these Parts have arrived, thank you ;) I am also considering this Solution.
@@acp2446 Thats awesome! I just found the Fan yesterday at the KTM Store for about 180 Euro and thought twice about buying it. Thank you, I will have a look online for this Fan.
@@acp2446 I just bought the Fan some Minutes ago at Ebay for 50 Euro in Total. Saved 130 Euro, thanks Mate! :) I also checked the Husky Power Shop (you can find all Explosion Drawings there) for the Screws. They do not mention the Screws for the bigger Fan. So I guess the old ones are suitable. Otherwise I will just go to the Home Depot and buy some new Ones. Now I just have to get the Cover from the KTM Shop nearby.
thank u ...so i dont have to use afthermarket pump
For me the Effect is less then expected… You need to make your own Decision if it is worth the Risk of having a second probably leaking Gasket and the Money
Typical German over complicating ( but very interesting )......
You can increase cooling by :
1.) Increase air flow ( by driving faster or adding second fan ).
2.) Changing thermal sensor for fan to start earlier.....
3.) Bigger radiator ( what most racing guys do ) ....
This bike has quite high compression ratio to squeeze a lot of horse power - that unfortunately goes against longevity and reliability and produces excessive amounts of heat ( that is normal ).
Fueling ( running too lean ) can also cause excessive heat - put it on dyno.
Thanks for these Tips. Its very interesting to hear about some bigger Radiator. Could you tell me if these are more or less selfmade or is there some Aftermarket for these Radiators? Could not find any… Maybe you can tell me some Brand or Manufacturer. Thanks!
@@Speelbird I am really sorry, I only know from my few friends who are road racers - that they have larger radiators fitted...
Check the radiator size of the factory Husqvarna / KTM rally bike ( i think they have 2 fans) - and see if they are running any bigger than your 701 and who is supplier ......
That Italian fellow Lucchese ( or similar ) building 701 rally bike may help....he is saying that they put bigger clutch cover on 450 - to increase oil capacity and reduce temperature that way....
Good luck and let us know what have you discovered.....
Kauf dir nen anderen Thermostat für den Fan der schon bei ca.80*C den fan einschaltet … fertig
Dann springt der Lüfter nur früher an und es dauert länger bis du bei der max Temperatur bist. Das grundsätzliche Problem löst sich damit nicht.
