wow so glad i watched this video, i want to learn all about vehicle repairing. never knew a engine cooler was even a thing, thought all the cooling was handle by the coolant/radiator.

Wow, great video for sure, I have developed oil leaks with my oil cooler and unfortunately, a slow coolant leak that I can’t seem to find, and brown discoloration a little bit at the bottom of the coolant over flow tank. I hope I can figure this out. I think I’ll do a leak down test on the coolant system. Hopefully I’ll get an answer.🙏🏻✝️

[@waterfall836]

Thank you for your explanation very good for me to understand why I have that problems. Short and sweet video

[@Blue_devil_209]

Awesome Video and breakdown of the 2 types.

[@tproc6642]

Thanks, I have a Pacifica with the failing plastic oil cooler. My question is, how do I know the extent of damage. The engine is at 95K ...and I believe should have many more miles. But shop is saying to replace engine, just from the block test.

[@webpro607]

I found that coolant was mixed with oil in my Jetta 1.6TDI, seems like a faulty oil cooler. How can i clean the coolant system from the oil (which become like a grease after it has mixed with the oil).

[@carmennunez8837]

Very useful. Thank you so much.

[@RiseUpRoyalAce]

Great video as always!

[@fallenone6]

Hello on my vehicle the engine cooler travels inside the radiator, i wanted to see if the oil is leaking inside the radiator, would you happen to know how to find that out? A test i can perform?

[@sarahandy9981]

My truck is a 6WH1 Isuzu EXZ prime mover.. the truck vibrates when running on ideal and it looses power when carrying load and running up a smoll hill.. can you tell me what's wrong with the truck

[@ivanhernandez5089]

Could a possible symptom be engine oil mixing in the coolant reservoir?

[@carlosmuler4773]

Very inteteresting and helpful information. This is the same as the oil cooler? Thanks

[@Top5AutoRepairs]

Yes, it is

[@im-dt2er]

Engine oil is in the coolant reservoir. Is that the faulty oil cooler causing that?

[@B.F633]

I have antifreeze leaking motor jumped from middle to hot in last than two miles. Cooler gets super cold. I do hope it's the thermostat ".

[@Panther-]

Yes I drive a mercedes jeep Had oil leaking from my car and having to top up my oil every 2 weeks took it to the mechanic 2 days ago to have it changed but took a while to go to the mechanic because one mechanic said i can still drive it did not realise it can cause damage to your car smh

[@sauldean6430]

Can this be solved by just changing the gasket?

[@sunsolstar]

Thank you

Can it cause low oil pressure

[@almoncashews]

I have a cayenne S 2016(twin turbo v6) have coolant smell, slow loss of coolant, oil in coolant but no coolant in oil. This has been going on for the past 3 months, also the oil temperature is higher than normal but not overheating, the coolant is at a perfect 200 degrees and have a oil leak. car runs perfect, no white smoke. 80k miles. Is it more likely the oil cooler or something worse like a head gasket or block?

[@al3xxx693r]

Just noticing the same with my 2006 cayenne S. Did you get to the bottom of it? Have ordered a new oil cooler myself hoping it is that and not something more sinister.

[@almoncashews]

@@al3xxx693r now it appears to be the heater core.

[@818nut]

Can you just replace the worn seal or gasket or is it best to replace the whole oil cooler?.

[@Top5AutoRepairs]

Best to replace the whole engine oil cooler

Might be a thermostat

[@raveon7260]

brilliant video,if the engine overheats because of the oil cooler .does the temperature gauge go up or will this remain normal. .thanks

[@Top5AutoRepairs]

It will cause overheating. Temperature will go up.

[@raveon7260]

@@Top5AutoRepairs thanks for the reply engine seems hot but the temperature gauge remains at 93 c max uk before fan kicks in which is pretty standard .thanks again

Thank you!!!!!!

[@EARTHKEENING]

Can coolant get to the oil because of bad oil cooler ? Or only oil can get to the coolant ? My volvo has coolant in the oil dipstick but I don't see oil in the coolant.

[@Top5AutoRepairs]

They can mix together. It also depends on the design.

[@EARTHKEENING]

@@Top5AutoRepairs I will change it with new one and flush the engine 2 times and will update . Thanks for replying Volvo xc90

@@nelsonudeh4473 i didn't do it yet I didn't receive the oil cooler the tracking show it will arrive in 6 days from now , I still can't find a case on KZbin like this case all people have videos of oil got to the coolant but no one has the opposite, I don't know but I start to get worried the it's the gasket.

Did you fix the problem? What was wrong ?

I dont think the sierra has an oil cooler, sounds more like head gasket or craked head/block

Its this can put the car in limp mode ?

Very unlikely
