[Vwdiesel] More Quantum Questions?

[William J Toensing]

Thank you Tony & Lillie for your response. Will check that out tomorrow. As to the overheating, I am beginning to think it may be the temperature fan switch which is supposed to turn the left fan on at low speed at 190 F & both fans on at high speed when the temperature reaches 205 F. I can probably figure out how to check out the system but any suggestions from you readers might help me save some time. Since this Quantum is 26 years old, some of the OEM parts are probably failing due to age & the 117,000 miles on the car. I drove the car on Sat., 8/30 & it did not heat up. The prior owner complained the car would overheat in hot weather when climbing mountain grades. The radiator does not show any signs of a head gasket leak as the testing fluid stayed blue. Also, the coolant return into the coolant recovery tank is steady. Am thinking of installing a manual toggle switch to bypass the switch & turn on both radiator fans on high when needed. Is this radiator coolant temperature switch easy or hard to find? Haven't checked locally yet.
