Voltage drop and temperature spike


Recommended Posts

Hey guys, recently while I’m in traffic I’ve been having a voltage Drop and temperature spike. I’m in Las Vegas and daily temps are 100°+. I just fixed a vacuum leak on my 4x4 actuator which was causing excessive oil to come out of the crank case breather. Do y’all think this might be related because of oil getting on the pulleys and I just need to clean them up and swap the belt or should I start looking in a different direction?

Power wash the engine off and use a good degreaser. Take the truck for short drive just a few miles. Then search the engine for a new wet oil spot or oil weeping. Common leak places are...

  • Vacuum pump seals
  • Tappet cover (cam cover).
  • Front crank seal
  • Gear case cover.

 

Unscrew your oil cap while idling if the cap moves you've got excessive blow by. Rare to see on our trucks. Really common on the "Common Rail" engines.
