Have a 2001 Chrysler Sebring 2.7 convertible. Fans don't cycle when they should.
Original problem was that the bleeder housing just exploded one day while driving. No
warning! The temp gauge didn't register hot or anything.
When I replaced the bleeder housing and bled the system everything seems fine until the temp
gets up to around 210-215 then the overflow tank starts to bubble and bucking sound. No
Fans. I can take the relay out Hi/lo and the fans go on and the car seems to cool. I can
unplug the sensor on the bleeder housing and get the fans to come on too.
There were compromises in the cooling system which I took care of.
I know that the system, according to previous research, has to hold 16 lbs. of pressure
before the fan relay gets the signal/pulse to come on and I'm sure with no compromises it's
Still no automatic fan activity.
I replaced the thermostat, toggle up at the top, the water pump seems fine, and the sensor
is new, came with new bleeder housing. I replaced rad cap.
I'm thinking that the ecu/pcm is not sending a signal to the fan relay. What would I check
to know for sure.
Oh I checked with an ohm meter the activity of the sensor with the engine running unplugged
and the numbers were going down on the sensor, don't know what that means exactly. I know a
little about the two wire and one wire sensors
So what can you tell me? I hope the answer is deserving of the charge.
