Engine Cooling problem
1989 Dodge Caravan 4 cyl Front Wheel Drive Automatic 150000 miles
Back from town today, I pulled up to the curb, attached the steering wheel to brake pedal lock while letting engine run a bit for the turbo's sake, I look at my instrument cluster and notice the temp gauge instantly peg to the top? None of the others move. I immediately remove pedal lock, and push down on steering wheel and gauge drops back to normal, release it and temp gauge reads at very top again. Weird!
I try another test, push down on the brake pedal.
Each time I push & release gauge reading jumps up & down. Really weird! At this point I adjusted the tilt steering to lowest setting to 'maybe' my only guess, to take pressure off pinching wires. I lightly reattach the steering pedal lock. Now I'm scared a wire or wires are grounding out somewhere so too nervous to drive Van now!
Additional details that may be related. Noticed rad fan not turning on, no codes I pulled the connection from the temp sensor and it comes on and then afterward gives me code 22 for low/high voltage. I forgot that code would disappear after so many starts and so went and shelled out $59 @ Napa for new coolant temp sensor, picked up a new fan relay as I have heard many times these commonly fail. 50/50 mix, bleed system, added new rad cap too. Still no fan coming on ever! Gauge would climb to 3/4s then drop but fan just never comes on.
Now with this newly discovered wacky gauge issue, I can't really trust the gauge reading at all!
I hope a pro here knows, & can tell me why pressure on steering column or brake pedal would cause temp gauge to jump to top. And, could this be related to why fan never comes on!
Many thanks in advance!
have the same problem?
