Where on-line can I buy a cap for the coolant overflow resevoir for a 1999 Cadillac STS Northstar V8?

Question

This is a pressurized self contained cooling system with a radiator that has no cap. The coolant overflow resevoir has the only cap but I cannot find one either individually or as part of a replacement tank? If you know the supplier URL and part number it would be greatly appreciated.

Answer 1

Go to a dealers parts department and buy one there.

AUTO LESSON 502!!!!The "GAS" pedal on an injected car is really the "AIR"pedal. Your foot only allows AIR into the engine. GAS is metered and injected elsewhere. YOur REAL problem is a dirty THROTTLE BODY and IDLE AIR CONTROL VALVE! Take $20-30 to the local quick lube, and have them clean your T body and IACV valve to SHOWROOM! WHile you are there, be SURE that they test for signs of SLUDGE and COOLING SYSTEM BREAKDOWN. Your engine was MADE to use ONLY MOBIL ONE 5W-30 or 0W-30 engine oils. ASlo get the ORANGE DEXCOOL flushed out at once, and get MERCEDES YELLOW coolant put in instead. THe reason is VERY simple if you read the DEXCOOLSETTLEMENT.COM web site. It has been PROVEN in lawcuirts across this country that DEXCOOL< the factory GM cooolant, will eventaully eat holes in your engine gaskets and cause COOLANT sludge to form in your RESERVOIR. There is a HUGE lawsuit about this, and millions of people are affected by it. GM bowed out and filed bankruptcy protection over it, in part. By using IOMPROPER AND CHEQAPER engine oil changes, you are TEMPTING FATE. CHEAPER oils amake acidic vapors that CLOPG up expensvie engine sensors, like your THROTTLE BODY and others, that cause STALLING, early oil contamination, and even CONVERTER clogging. MOSt NORTHSTAR engines are tired at the 100k mile marker. ANyways, this $20 fix usually works, and there are thing you can do to protect that engine from going bad early, SYNTHETIC OIL MUST BE USED IN THERE or engine damage will result over time, guaranteed. GOOD LUCK!!!

Auto Zone. They have over 7,000 parts and if they don't have one can order it for you.

Also auto salvage yards are a good source but you need to make sure the part is good.
