Question about 1999 Oldsmobile Silhouette

1 Answer

I've been reading alot of people having trouble with the radiator fans on 99 oldsmobile silhouette not working but have found NO solutions. All the gaskets on the motor have been replaced, the thermostat and new tcs but the fans still will not engage until motor reaches 220-230 degrees, by then its too hot. Do you have a real solution to the problem?

Most cars temperatures are at around 225 degrees before the high speed fans turn on. And then it only reduces it to around 210. If your car is too hot, first you will hear the lifters pinging and tapping. Then you may hear some rod knock. After that your car will just shut down. Too late then.

SOURCE: Olds silhouette heater blows cold air

as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference

SOURCE: 99 vw beetle, been overheating for a couple weeks

Check around, I'm sure that you can find someone that can do it for less money.

I don't know if the radiator was bad or not, so I can't offer advice on that.

If your mechanic charges $100.00 per hour or more, I can see where they get the quote from.

If you need more assistance, post a comment.

Where are you located?

Maybe we can help suggest a mechanic for you.



Thanks,

Tim

SOURCE: lower intake manifold gasket leaking 02 Olds Silhouette

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

SOURCE: cooling fans dont engage! 1998 oldsmobile silhouette!

Your Problem Can VERY WELL BE with the Temp Sensor, As It Is the First in This Electrucal Circut . it Waits for 210-230 Degree Engine temp and Gives that Sygnal to the ECM then ECM Grounds out the Cooling FAN RELAY To Turn ON the FANS and the Temp Sensor is Usualy THE #1 Culpret Closley in front of the RELAY.
There are 2 Sensors On this Vehicle The One You Replaced and One Located At Trans Side of
Engine Closer to Front of Vehicle At the Head ,Thereis a 2 wire Plug On it and This Sensor Goes to the ECT witch CONTROLS COOLING FAN RELAY. Hope this Helps and if you Need A Diagram For this It Must be Emailed as FixYa Does NOT Support Large Picture Files. My Email Add. Is MY

Radiator fan doesn't work


Always keep an eye on your engine temp gauge, find rad thermo switch and bridge connection (it's a switch anyway) this should bring on rad fan. Thermo switch usually on thermostat housing or radiator body housing !

Recharge A/C question.


The amount should be on the radiator fan shroud.These system hold around 2 lbs.of freon when empty.This also depends on if you have rear a/c or just front a/c.If there is some freon in the system the compressor will cycle more often and the system will not get very cold.The other thing is if there is a leak the freon you put in will eventually leak out.There is a bulletin for a/c leaking from the a/c condenser on these vehicles.I have found a few of these with leaks and they where on the passengers side lower bracket.If you can get the freon with the dye in it then you should use this that way if it leaks out you will be able to check for the leak.Hope this helps and let me know if you need more help.Good luck.

I have a 2000 Oldsmobile Silhouette that just started overheating because radiator fans don't come on. Can you tell me where the relays/fuses are located? I looked in the fuse box but none of them seem to...


In the black plastic box in the engine bay on the left or right side or against the firewall. The is top held down by plastic clips. Release them and look at the bottom of the top piece will be a diagram that will tell you where the cooling fan relay or relays are.
