Engine temperature

Recommended Posts

Just changed the serpentine belt & impeller on my 250 CR, Volvo 5.7, the motor always ran @ 160 degrees.  Now it warms up to 160 but as I accelerate to plane the temp slowly drops to 125 degrees, once I slow to idle it will rise back to 160.  Never overheats and runs smooth.  Any ideas?

let ne see if i understand corectly


Stoped engine starts to heat

running drops.....


Did you check the belt? is it the corect one and is it tuned?, after this is the temp sensor good?, maybe a bad sensor or gauge reading wrong, or just maybe you need to check with a connector to engine and see what is going on with the engine
