I replace my thermostat to 180* in the summer and the needle would run at the A or the M on Normal, Now its winter and my car tuns 1 notch lower on the L, in the winter, and it takes forever for it to warm up, what should I do? is it better that it runs colder or what?

its fine that it runs cold but are you sure that the t stat is not a defective one and is stuck open now

you stock gauge may or may not be accurate, they really suck and its old... and maybe your thermostat's stuck open?

It'll use more gas if it runs cold. It sounds like the thermostat to me. Does it get colder when your moving? Might have gotten a bad thermo or coolant is getting buy some how.

cammedlx

actually its the other way around i wish i had half the knowledge you did MD you are my hero

i dont konw if its stuck open, about a weak ago the coolant light came on and I smelt anti freeze, and from then on it runs colder, the term worker over summer, it also has a life time warrenty, man its a hassle to replace. what do you think sould I replace it?

cammedlx

well its not going to hurt anything and i have never heard of a car using more gas the colder it runs maybe throw out more emmisions but who cares

90Mustangfan

is that what the problem is though? the therm is stuck open?

mdvaldosta

probably

will it hurt the car or its performance if i dont replace the therm?
