My 2007 HHR is running slightly hotter than usual. I notice that the cooling fan stops when I turn off the engine. Should it continue to run for a while?

 

Only if the engine is really hot. Don't know about a non-turbo HHR but my cooling fan will only stay on after shutting off the motor if it's over 216F. Otherwise it turns off immediately. I don't recall my old 06 2LT ever getting hot enough to have the fan run after turning it off.

 

It's not as hot here as in TX, obviously, but mine has never run after shutoff.......

 

my fan has never kept running after it is shut off..

I have heard other brand vehicles that do, do this..

 

Sleeper, Run it hard for about a mile and then pull over and shut it off.

 

When the engine coolant temperature exceeds 125°C (257°F) at key off, the fan will run for up to 108 seconds.

 

At 257* I would think you could fry eggs on the motor.. That just seems awfully hot...Too Hot.

 

Mine's done it a few times on the hotter days. Never ran for more than a few seconds though
