Please i am new to Volvo cars and need help.

I recently got an S60 T5 2006 with 144000 miles on it. Recently did the PCV, 9 days later i started to notice little oil in coolant tank, also noticed the water in the coolant reservoir boils.

The day before i noticed oil in the coolant, i accidentally ran into a pot hole on the road causing the underside of the passenger area to have a strong impact on the concrete road.

There is no oil in the dipstick for the engine and transmission.

Please what could be the cause?

 

"Boiling" coolant is an indication of a leak in the system and the "boiling" is actually just the air moving through the system to the highest point to be released. If there is oil mixed, it could mean the pothole impact might of damaged the oil cooler and there is a mix happening there. It is located on the rear of the oil pan.

There is a different dipstick for the transmission fluid, it is under the coolant hose on the driver side.

 

Okay Thanks, I am anxious it might be a blown gasket, the oil cooler replacement should arrive by weekend, fingers crossed.

 

I would investigate further and do a full proper diagnostic before replacing parts! You can test the coolant for hydrocarbons with a cheap tool from the parts store to see if exhaust gases are getting in the overflow to check for a head gasket issue.

 

Thanks, i was able to get the old oil cooler off, found traces of coolant on the oil side, found what appears to be a small rubber piece from the side of the oil cooler that connects to the sump.

 

Could be part of the gasket for the oil cooler
