Subject: [MBZ] Coolant Gauge Fix
I have been struggling with the coolant temperature gauge on the S500. It's
been wonky for a while, and driving me nuts in the process. Typical
behavior would be for it to show the coolant temperature as the engine arms
up, then when it approaches operating temperature, BOING! The needle goes
full scale.
I had tested and replaced the sender, verified that the wiring harness was
intact (found a break in it) and gone completely through the circuit to the
point where I was convinced the gauge itself was bad.
I snagged a complete instrument cluster for $100 from a guy parting out a 95
S500 sedan. Yesterday I pulled my cluster, swapped the gauges from his
cluster to mine, and while in there cleaned and replaced lamps, connections,
etc. I also took the opportunity to transplant the little rubber pads that
are located around the outside of the cluster that keep it from slipping out
of the dash, since only one of mine was left.
Voilá! I now have a working coolant temperature gauge. Amazing. What's
even better is to see that in a mid 80F ambient with the AC on I am running
right around 82C. Since the gauge had been pretty much nonfunctional in the
past, I have never had a good idea where the engine was running
temperature-wise.
I love it when everything works.
Dan
