Temp. Gauge Gone Wild * solved (bad connection)

Horsehammerr · Post by **Horsehammerr** » Fri Jul 23, 2010 3:23 pm

My Temp Gauge comes on when the key is turned on , but when turned to start and engine is running the gauge reads flat to the left, as in 100*. This also makes the engine run extremely rich , so rich , I think I can see the fuel gauge going down as I drive. HELP ?

Check your battery cables and connections. It could also be the ignition switch or the instrument cluster connections. Check , clean and lube them all.

Thanks HJ, I will go through the whole electric system and clean it up and , lube with what ?

Dielectric silicone (electrical grease)

This will reduce oxidation , promote a good contact and seal the connection.

Pay close attention to the battery cables and their connections. The bolt can tighten in the battery terminal and not on the cable. The end attachment at the engine can oxidize and have a bad connection.

I had my old truck catch the little wire to the firewall on fire. It smoked it when I started it. The connection at the engine block had oxidized. Hot weather seems to bring out the best in everything

I'll get on ASAP. Have been into mid to upper 90's here with 80 percent plus humidity. Been like this since end of May. Every summer we live in a natural Spa.

I had the very same problem... I fixed it by unplugging the temp sender plug and cleanning the conection. When I unplugged it, it was not plugged in all the way. I think I knocked it loose when I changed the spark plug wires.

Sounds like a good place to look. Can you point me to that temp sender plug ?

It is on the drivers side by plug 3. It is a pita to reach.

Thanks for the Pic. Jongo88. This is a major help, and you are right about the PITA. Right between two of the hardest to reach plugs. Thanks GM engineering !

Any time bud. That's why we are here...

I'll do the clean and lube later today but, after finding the connection and just jiggling it a little the temp gauge is now working. I'd say that's a for sure sign it needs cleaning, along with all the rest of the elec. connections. Thanks for the wake up HenryJ and Jongo88.

All cleaned up and Dielectric Silicone lubed. Everything working well.
