Coolant leak on oil cooler.

FrankMstein · 09-20-2021, 06:51 PM

Doing some re-screwing of my front lip tonight and noticed my oil cooler had coolant on about 30% of the fins but not dripping, slow leak?. Those of you with experience in this, what is the most likely culprit? TIA.

most likely dropped from above... check the coolant levels for the engine and intercooler. Common for the seams of the reservoirs to leak... check for dried coolant, wipe it off and check again after a couple miles to see if it comes back...
