Question about 1998 Oldsmobile Silhouette

Temp gauge suddenly hot

I have a 2000 Silhouette that just had a bypass hose replaced. Since then the temp gauge is getting hot. Mechanic replaced the thermostat but doesn't know what else it could be. Maybe an expensive internal problem he said. Any ideas or similar problems.

Could be an airlock in the cooling system.
If a Mechanic has looked at it can you please list everything he has checked .
Did he check for a blown head gasket , Water pump , Test the temp sender .........?

Where is the temperature gauge in a 2002 silhouette?


The temp gauge is in the dash. The temp sending unit is on the drivers side of the engine right below the thermostat housing where the upper hose is attached to the engine. This would be on a 3.4 liter engine. I don't think that is you problem but it is possible. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!

Temp gauge goes up to hot then back down only a few times


This is a sign that the thermostat is sticking shut and then opening after the temp gets past a certain point. If the heat gauge goes to high and then drops down suddenly, this is the likely culprit and you need to replace the thermostat - again.

I have had them arrive from the parts store and be defective.

Air from heater not getting warm. At best, tepid. Is it probably the thermostat, and if so, how do you replace it?


if your temp gauge reads normal then it needs a new heater core
if it reads colder then normal then it needs thermastate
it is located on the upper radiator hose on motor

The cars temp gauge goes up and down,and looses heat. I am thinking a bad thermostat or lack of antifreeze/coolant. Is this a correct assumption?


My mechanic has had my Silhouette for two weeks for the same problem. Engine Tempurature is running at 195 degrees when the gauge is pegged on overheat. Normal operating temp for this van is 220. So it is not overheating. Had the cooling/heating system flushed and refilled, bled and topped off. Still the gauge is up and down like a yoyo. Still looking for answers.

96 Golf reads hot after replacing Coolant-engine feels cool.


Had similar problem on my 2000 cabrio---hit the dashboard lightly above the temp gauge and it dropped to normal reading---the temp gauge spring was oversprung from the previous overheat problem I had---as long as the engine is cool --then so are you

2000 Elantra Overheating


First when vehicle is cold like in the morning check and make sure that the vehicle has enough coolant/ antifreeze in radiator and reservoir. If coolant is need use a 50/50 mixture of water and antifreeze. You will need some time to do this let car run at idle until the temp guage is in the middle NOT+ normal operating temperature. At this point if the thermostat should be in the open position. Let vehicle run and check to make sure that radiator fan comes on. This should come on when guage is about midway/half way. If temperature rises above half going to h/hot and fan doesn't come on, you either have a BAD FAN BAD FAN SWITCH BAD FAN RELAY OR BLOWN FAN SWITCH FUSE. You will need to check all of the following I will help if its needed. If fan comes on and doesn't go off and vehicle continues to get hot even with fan running. Feel radiator hoses and see if the lower radiator hose is cool/cold. If it is you have thermostat that stuck closed. Replace thermostat and fix problem. If all the above is good and vehicle continues to over heat. THE BAD NEW IS THAT YOU MAY HAVE A BLOWN HEAD GASKET /CRACKED HEAD /BROKEN WATER JACKET. Basically you will need a HEAD JOB at least a head gasket. ONe tell tail sign of this is oil looking like milkshake/chocolate milk-a creamish while residue in oil or antifreeze. Contact if you need hel0p. Good Luck and thanks for using FIX YA

97 f 150 runs hot for minutes then runs ok


It could be a faulty thermostat. Did it do the same thing before u replaced the t-stat? It sounds like it's sticking closed, then all of a sudden it opens, coolant flows correctly. I'd consider changing it again. Check to make sure parts store is giving u the correct temperature thermostat also. Maybe it's too high for your Ford, delaying the opening.

Problem with heater


hi what you need to do is lift the bonnet find where the two heater hoses come out of the bulk head while running the engine they should both be hot same temp both hoses if not there is a air lock in the system if it was allright when it went in it should be ok when it comes out you will need to bleed the system the engine temp gauge is not low by any chance is it if so replace the thermostat but i am sure once systems been bled it will be ok yates210456
