Default thermostat dead?

started driving my car again for the first time since in about 8 months. had no issues when i parked it. took it to the track tonight, held temp just fine driving out there. when i left, temp came up to 190 so i turned on the fan and headed to the freeway. got on the freeway and the water temp was 176 so i turned off the fan. driving home i looked at the gauge and water was at 146* (according to the pms) and confirmed by my autometer gauge. drove the whole way home and and it never got higher then that.

im assuming the stat is sticking open. sound like that to you guys?

fwiw, i have a 3 core aluminum radiator, 180 stat and standard rotation water pump (got it at autozone, $35 deal)

If the running temperature is lower than the thermostat temperature. It's either stuck open or leaking internally.

Not quite on topic with your thread here but I think running an electric fan while driving down the highway is a waste of electricity.

yes i do, you still live in the area? would be nice to have some one go to the track with.

alright guys, sounds like a cheap fix. no more track days this year (except next week but its going to rain) so i have some time to care of this as well as my never ending tranny leak.


fivepointohh, whats good gas miliage? your talking to a guy that use a f150 with a 9" lift and 37" tires for a DD
