Oil residue found in radiator

[Thhmarc]

Dear Bros, recently found oil stains on the radiator cap. There are some oil residue when I look from the top of the radiator. What could be the probable cause?

I had it before, but in my case it became Milo inside the radiator tank. The residue could be EO or ATF. It's likely you have a slight leak somewhere. Get it fixed at a good workshop before it gets worse.

It is leak at either engine oil cooler or gearoil cooler... it will cause engine overheat...

Please get it solve ASAP

Normally they just change both of the cooler...

If you use water wetter etc - the brown stuff floating around is normal.

If you mix silicated coolant with non-silicated coolant, you would get that brown stuff as well.

Best is to go to a site sponsor WS and ask them to have a look..........there's a link to a directory of workshops at the top of the forum.

I am just using water , no coolant, can anyone show me how the engine oil cooler and ATF cooler looks like?

Technically it's called a heat exchanger.

No coolant?? Holy cow... Best to bring it to a site sponsor workshop quick to see where it is leaking. No point guessing here...

Sean, we have lots of telepathic mechanics here who can diagnose what prob a car have thru description by words.
Why waste money and time sending to ws.

actually the purpose of asking is to know what to expect from the bros that experience similar issue....

Like I said, it's normally the EO or ATF heat exchangers. But could be a whole variety of other parts esp since you mentioned that the cooling system has not coolant inside. Hopefully not anything inside the engine. Better get it to a workshop to be checked out... Good luck!
