It's possible you have a blown head gasket. In that case, the heater core which is above the engine fills with exhaust and stops working. To verify this condition, check exhaust for excessive white smoke. If leak is still small, it's possible you won't see much. In that case have a shop check the radiator for hydrocarbons (exhaust). If the test shows any in cooling system, you definitely have a head gasket problem.
I'd also check the thermostat. Sometimes it can give similar symptom but more often than not this will trace back to the hg.

Hi and welcome to FixYa!

The fan relays or fan motor itself can be faulty that's why it tends to overheat. You will need to have it replaced if that's the case.

The motor shakes so bad it's because that you have a faulty TPS (throttle position sensor). If the TPS is faulty you'll have erratic idle.

One more reason why the engine shakes when driving is because the transmission fluid is burnt. If the fluid is burnt it tends not to shift so I suggest that you have the fluid replaced.

Hope this information was helpful enough and thank you for using FixYa! Have a good one!

2001 olds silhouette engine overheats


Time for Intake Gaskets and possibly head gaskets, very common problem with these, the intake gaskets go bad and the coolant actually burns in the cylinder and of course the cylinder pumps air into the coolant system because of intake gaskets being bad. :-(

'98 olds silhouette van, cooling fans work when a/c is on but will not work at all when a/c is off


But is the engine overheating ?
Electric cooling fans will sometimes come on after a vehicle is parked,
(It actually heats up when stopped), but not when it is rolling down the road
because the movement is applying some cooling effect to the engine.
\
If the engine is not actually overheating, then the fans may be working
normally. Also, make sure your water/antifreeze mix is correct by using a
specific gravity tester. It is a tube with 4 or 5 balls, some of which will float
to give you a reading. Contrary to popular belief, More is not better when it
comes to antifreeze/coolant. It needs water to work properly. Too strong a
mix will actually make your vehicle run cold so that the temp sensors and
heater will not function properly. The engine will not achieve proper operating
temperature and may actually damage some of the components by running
it cold, affect timing, spark, etc. This could also cause the symptoms you
describe. The engine would not actually reach the proper heat threshold
until you added the extra demand of the AC heat transfer. But the first criteria
would be whether the engine is actually overheating / or in normal range .

My van is running hot changed the thermostat still running what else could be wrong


Could be lots of things. Your fan could not be working or not being told to turn on at certain temp. Your water pump could be broken or your rad cap seal could be bad and leaking coolant or not holding the pressure as the system needs to be.

My 2001 Nissan Quest temp gauge rise to hot, cools then get hot


You better not be driving your car overheating like that and shutting off on you! It sounds like you've most likely lost all your coolant due to a leak of some sort, and your engine is overheating. I would take the vehicle to a shop make sure you don't have some kind of major coolant leak. They'll also want to do a "block-check", which is a fluid that can detect combustion vapors in the coolant, that would indicate you've blown a head gasket due to overheating. It's very bad for an engine to run without coolant, even for 10 minutes. I'd have the vehicle towed in unless the shop is right around the corner. If you'd like to check your coolant level yourself, make sure the engine is cold or at least the vehicle has been off for an hour. Checking the overflow tank level may not be good enough. You'll have to remove the radiator cap and determine if you've got any coolant in the radiator. If not use either regular pre-mixed green coolant, or if you have non pre-mixed dilute it to a 50/50 ratio coolant and water. I wouldn't continue to drive your van with it acting up like it has until you can get it checked out.
