SOURCE: Where are the cooling fan relays for a 1998

Are you sure that you don't mean the cooling fan control module? It should be located up front next to the cooling fan. It is square shaped and has a long square shaped plug going into it. 00114_cooling_fan_control.jpgReads the temperature of the coolant and passes the information to the engine control computer (ECC). The ECC receives analog information and signals the cooling fan switch to cycle the cooling fan on or off, as required.

My 1997 cadillac deville, northstar w/85, regular oil changes, burns almost 2 quarts of oil every change. It is not leaking.


If your car is losing oil, and if there is no evidence of oil leaking, there is no question that it is either losing it through piston rings or through the head (head gasket or valve guides).
Best thing to do is use a HEAVIER WEIGHT oil than specified for the vehicle when new, regularly monitor your oil level and be sure it never falls below one quart low, and consider having the engine overhauled when you start noticing a performance deficit or hear mechanical noise (such as rod knock) from the engine.

1994 northstar motor leaking oil from engine block, where could it be coming from


Most likely it is the rear main seal. It is the seal that surrounds the crank shaft as it extends out to the transmission. The rreplacement of this seal involves removing the transmission. You could also have oil leaking from the rear side of the oil pan or the rear of the valve covers. But in most cases you can see this leakage. Therefore it is most likely going to be that rear seal.
