My 2003 S80 has 340k+ miles on her. Had a code I don't remember a couple years ago ,got a thermostat from Volvo that I was told was wrong. I think that guy was wrong. My engine doesn't overheat per se but is hotter than you'd think it should be. Of course My transmission slips, it was in limp mode. Had the shift solenoids replaced it drove beautifully but is repeating the earlier issues. I'm thinking transmission fluid not cooling, I need to check to make sure old thermostat not completely done for. Today cleaning the mass airflow sensor (it hesitates on acceleration) After all that's done any suggestions? I need a new view . Thank you
that green antifreeze with ethanol glycol will eat into that impeller since its plastic and make it soft . Should of used the other type thats orange or brown .Same problem with changing out heater cores if the core has plastic sides it will eventually leak with the green antifreeze makes the plastic weaker or just replace with full aluminum core so it cant happen .
Robert DIY Luckily, no. The person I bought it from shut it down and had it towed as soon as the temp started to rise. Then, I was able to put it on my lift, tear it apart and found all the impeller fins sitting there, broken off.
@@MidknightMechanics no sir. The guy i bought it from 3wks ago said its never happened but when i looked through the car and fluid levels ect there was almost just a cup of coolant in the res so i topped it off. He said in modern cars if i dont do a flush then something can cause the enging to get hot and shut off. Mind you hes supposedly a 24yr old machanic for the army but to me i feel i got a lemon. Ive never had a problem with any vehicle ive owened in 28yrs and ive had new and old cars and ive never had a coolant problem like this.

Midknight mechanics thank you very much for your help 💪
New meaning to an "interference engine"!
Hehe,I am Volvo mechanic.Never change OEM pump ,they last long time,aftermarket pumps last up to 30k miles

You didn't have any issues with the PCV system? Got a hell of a bad oil leak I'm fixing. Resealing is terrible.
On the S60's I have, with that silly oil separator under the intake, but no pcv issues with this S80- but that was just lucky..
Was the head gasket breached on the car since it overheated?
Robert DIY Luckily, no. The person I bought it from shut it down and had it towed as soon as the temp started to rise. Then, I was able to put it on my lift, tear it apart and found all the impeller fins sitting there, broken off.
How can you tell if the head gasket has been breach?
Is it easy to fix? I have a s40 2010 and would the engine giggle or shake rough?
Not easy. This involved an entire timing belt change. Nope, it would'nt make the engine giggle or shake. Goodson do you have a check engine light?

@@MidknightMechanics so would the engine have a transmission problem you think?
This the same issue with the 3.2?
Only if someone put in a junk, aftermarket water pump.
Engine coolants temperature sensor?
You got it my friend. Also you must have meant, on the thermostat housing, not the water pump.
"Huge tune-up"- what all did you do to the car?
Full timing belt service, tune up, front control arms, tires, good amount of stuff. Then about 2 months later the transmission started slipping.
What did you do about transmission slippage?
What’s the name of the sensor that goes on the side of the water pump
coolant temperature sensor
