Want this question answered?
The fans are controlled by a temperature switch, which normally turns the fans on when the engine temp reaches about 212 to 220 degrees.
A lot of fans of Chevy
Cooling fan is desgined to come on when coolant reaches 235 degrees Bad temperature sensor?
check power to fans,if power check fan sensor!!
You may have bad temperature control sensor (next to thermostate where water enters the engine. Also near the air filter). If not that it is PCM module or fan control relays. Try disconnecting the connector from the temperature sensor, if fans come on the relays are OK.
did you check if the radiator is plugged? Check for operation of the cooling fans. Turn on the A/C to see if the fans come on. If they do not come on the fan motors, relays or wiring need attention.
Yes they come with 120mm Ball-Bearing Fans.
No!
The fans on a 2000 Chevy Malibu engage when it reaches a temperature threshold around 200 degrees. It then brings the engine temperature down to an acceptable level before it is again shut off.
Very possible your temperature sending switch is bad. If both fans work with AC, then it's also possible you have a wiring issue.
Hi, The cooling fans in these vans are controlled by the engine computer, which controls 3 different relays to turn the fans on at low and high speeds. There are also a couple of fuses that supply power to the fans. So you have a few things to look at. The relays and fuses are all located in the fuse box that is under the hood. I would start there, using a multimeter to check for power at both sides of each fuse. There should be a label inside the fuse box that will help you locate which fuses to test and which relays are used for the fans. I have provided a link that describes the system and shows how the system is energized when the fans are on low and high speeds. Good Luck, Greg
You made the mistake of buying a Chevy Malibu. Seriously though, try replacing the fans next. Trip to the local junkyard would be the cheapest, although fans aren't exactly that expensive at your local parts store.
