Question about 2000 Oldsmobile Silhouette

1 Answer

My olds silhouette, (2000) has 100,000 miles and seems to loose power when traveling uphill after it has heated up after 70 or 80 miles travel. Could it be the fuel filter or a weak fuel pump?

You could very well have a pump that is weak and loses some of it's pumping power after it has gotten fully warmed up. Have you ever noticed a temporary improvement in power after refiling with cool fuel? A test drive with a fuel pressure gauge should tell the tale about pump condition. Usually a restricted filter will cause a starvation problem all the time instead of just after a long drive. It certainly wouldn't hurt to change the filter but I doubt that it is your problem.

The battery light was on because the engine stopped running. The alternator was not charging the battery.
On a model that new, if the engine did overheat the computer could kill it. A stuck thermostat comes to mind. But your temp gauge should have been on the hot side.
Its also possible something locked up and is preventing the engine from cranking, such as the water pump or alternator. You may need to remove the belt to verify. If the belt is slipping it would not power the water pump to keep the engine cool.

Have you checked your oil and fluid levels in the engine and transmisson.
if it's a manual could the clutch be worn out causing the high rpm and thrust bearing noise in the clutch.

Antifreeze leak coming for around the oil filter and dampner pully. It doesn't seem to be coming for the water pump.


Make sure that you confirm this, as sometimes (not often) water/coolant can travel uphill....i would strongly suggest using a good torch and hand held mirror to trace the coolant's path, so as to avoid misdiagnosis.

sounds like one of two things first is to check condition of all drive belts if they are all good dont let the miles fool you if the car has been driven a bit harder or had alot of uphill driving these reduce clutch wear enormously
