Is 210 the normal temp for a 2000 cadillac sedan


Hello there and thank you for choosing fixya :
To answer your question yes the temperature is normal for this vehical 205-210 is right at the normal range Normally you will have the 185-210 deg. thermostate installed in this vehical ''
You should notice that it does go up and you notice that it goes back down around the 210 degree mark this is telling you that the thermostate is working fine ok also if yo notice that it goes up and stayes up over the 210 -then you may have a problem this could be the thermostate may not be operating properly or the radiator may be clogging and needs to be flushed or your antifreeze mixture is not correct ok?
Hope this has helped you out
Best regards Michael

MY A/C WORKS PROPERLY HOEVER THE HEATING SYSTEM IS NOT WORKING. AIR COMES OUT BUT IT'S COLD. WHAT SHOULD I BE LOOKING INTO?


a stuck or broken thermostate would do that if the moter temp takes a really long time to warm up the thermostate is stuck open and needs to be replaced if the moter warms up to fast or over heats the thermostate is stuck shut and needs to be repalced. the heater core its self could be plugged and may be fixed by back flushing with water if you do it your self flushit seperate from the moter to prevent what ever may have plugged it from re-entering it.

Change thermostate and make sure there is enough coolant (not water) in the system.
Check that the thermostate sensor is working properly.

I do not have enough heat in my 1994 dodge ram truck


I expect the thermostate is stuck partially open not allowing the engine to come to proper temperature. Replace the thermostate found under the goose-neck (follow the upper hose back to the engine) under this piece is the thermostate. Be certain to clean all of the old gasket material away and use a new gasket. Watch to be ceratin the thermostate is not put in upside down, if this happens your issue won't be not enough heat but over heating.
I hope this may have been of help,
Tom

My lumina is geting hot because the water dont circulate


ONe of two things,your thermostate has gone bad or the water pump is bad. Regardless if your are going to change your water pump, it's a goos thing to change your thermostate too. Good luck.  The water isn't that hard to change on the 3.4 but the thermostate can be a pain.

How to change out thermostat in 1991 buck centry 3300


your thermostate is probably on the block sideways in whitch case you need to remove the air filter outr of your way and loosen the clamp on the thermostate housing. from there take out the 3 bolts holding the thermostat housing in place and remove it. Caution water/antifreeze will come out. take the thermostate out watching where the gasket has been placed and install the new one after cleaning the suface of the old gasket. sometimes it is good to use indian head gasket sealer. there will be 2 bolts on top and 1 bolt on the bottom under the housing. install the new thermostate tightn the hose replace your filter and fill the over flow resivor only to the point on COLD MAX. take the cap off the radiator start the car wait for the thermostate to open and fill the raditor the rest the way up. if it starts to boil over just shut the car off and let it cool than add more water *** needed...
