High Temperature Problem

Hi my 06 gt had a temperature problem yesterday, i was going to the track my 06 gt had the front nose mask on, i put it on to protect the front bumper.... the temperature was fine all the way to the track, but when i got there and put the car in Park the tempurature just flew all the way up..... it scared the .... out of me .... so i turn the car off......i took of the front nose mask and turn it on again... and the temp normalize.... so you guys think that the front nose mask has something to do with it? i went back home without the front nose mask and the temp was perfect.

I think the same... i'm planning of cutting the mesh that cover the front grille....

is there an aftermarket thermostat for the 06 ??

anyone else have an opinion?


Thanks....
