cars getting hot at idle
 

will a TII hood cause an N/A car to idle at a higher temp then normal? When i drive it goes back down to 1/4 the way but while im idling sometimes it will go up 1/2 way. This doesnt happen everytime though. What could be the problem?

No... by all means it should make it cooler (or at least increase its cooling efficiency).

I'd say your fan isn't moving enough air.

Wouldnt it always run hot though at idle? it only does it some times.

uh I'd say a problem with your thermostat or your stock gauge

it should stay constant

if your really wana know your temp get a aftermarket gauge
