Northstar Engines and System Technical Discussion Discussion, 99 deville fans just stop both of them in Cadillac Engine Discussion; i bought a manual ( NOT A REALLY GOOD ONE its the 99 - 05 mostly bout new ones, anyhow ...
i bought a manual ( NOT A REALLY GOOD ONE its the 99 - 05 mostly bout new ones, anyhow i saw where its talking about the fans... told me it could be a replace motor problem.. im praying im not going to have to go that route! anyhow , iv been having heating problems,, the waterpump leaked 5 days ago and he says it cuz i was driving long on a bad therm, it over heats... been staying cool cuz i only drive short distances plus i constently water the radiator behind the fans, this time i did that and the top of the engine ( it was steaming ) ... anyways well i did not see the service engine light come on till i watered the radiator and the engine.. the block box in the back.. was steaming when i wet it.. well wwhen i did this turned the car on started watering more, i saw then SEARCH ENGINE, and was wondering, it never came on for the vacuume leak, or waterpump , cuz i guess the car does not recognnize, nor the therm and i know its not that... i looked were i was hosing, at the fans and the fans did not come on even at 196 F , what may this relate... im hoping not a replace motor ( ITS THE BOOK GENERAL MOTORS DEVILLE 99-05 CHILTON ) its told me that, also said i can check if to replace.
If the engine is overheating and cooling fan is not coming on when the motor electrical connector and connect the motor directly with fused jump wires . if the fan motor doesnt come on replace motors..
Well the book has shitty pics on how to do this... can also someone tell me how n good detail cuz the book is shitty. No good pics illustrations
DO NOT EVER SPRAY OR DUMP WATER ON OR NEAR THE ENGINE !!!!! No wonder you're getting all sorts of warnings and lights !!! The "black box" in the back - ignition coil pack ??? It's now a wonder the engine even runs at all.
Your thermostat begins at 188 and is fully open at 206. The engine is SUPPOSED to run at 195 - 215. Fans do not even go to SLOW until 224 (that's NOT overheated) and FAST at 236 (that's NOT overheated). With some A/C or DEFROST function set, fans run in SLOW all the time.
DON'T EVER SPRAY A HOSE ON THE ENGINE.
Somebody had better read this guy's posts again and figure out that he has no idea of how the cooling system in his car works. Spraying cold water on a running engine in order to cool it down ??? Get serious..............He posted that the fans didn't come on at 196 - the thermostat isn't even halfway open at 196 !!! He's getting ready to dump a lot of money for nothing.
The Chilton manual is useless - you need a real GM/Helm service manual. eBay or www.helminc.com.
