Thermostat???

[shawnira]

I have a 1991 S10, and the temp. gage is pegging higher and higher. I suspect the thermostat. Is it any harder then "the old" ones to replace...or through out? I live in california, and have always left them out when I had a temp problem.

Any "need to know" info. before I pull it....throw it... and reseal the fittings?

dont just throw it away , get a new one , its less then 5$ for a new therm and gasket , and you want to have it in there , so the engine actually reaches operating temperature, youll also save gas by leaving it inn , cuz when the computer thinks its cold , it gives it more gas , but other then that , it could also be your radiator plugged up , or could be a fan clutch thats just not workin as good anymore , coudl even be the fins in the water pump eatin away. theres more the one part to the cooling system

Whitetrash is right, If I was you I would use a prestone flush when I changed the thermostat, and hope for the best

Also replace the rad cap.

Similar problem, as I have replaced the thermostat, and the radiator cap. The radiator has been flushed, and the water pump said to be working fine, according the the attendant.
I find when it gets above 60 degrees outside, the temperature go above 210 while on the highway for any length of time. (My drive 1s 50 miles to work)
So, I see someone suggested the fan clutch may need replaced.
How would you know by looking, and do you need to remove the belt to replace it.

mine usually runs at 200-210, always steady, fresh coolant+water pump, and still same.(water pump blew through the weephole).
