just wondering if the IC pump is suppose to engage as soon as the engine is started or if it is temp sensitive like the cooling fans.. tried searching with no results.

 

As soon as the engine is started. It's just like a water pump.

 

thanks.. only asked because i changed my engine oil earlier today and noticed the coolant wan't flowing so i reached under the car to see if i could feel coolant flowing through the line and when i looked back in the engine bay it was flowing. i didn't tap the pump or anything so i wasn't sure.

 

if you crank your car, pop the hood, and check for coolant flow, and there is none, something is wrong.

 

theres a 10 second delay between turning the key and coolant flow, if youre tune file is stock
