Check the block heater in your Series 60

[Arcticdude]

I've had the block heater fail on my Series 60. It's had coolant come up through the electrical connection and corrode the heater housing from the inside.

It's screwed into the oil cooler.

If you have to remove the oil cooler to get the block heater out, David has a very good
thread about that procedure. It's posted here: http://www.wanderlodgegurus.com/showthre...ock+heater

There's a very distinct marking from the coolant seepage on the outside of the oil cooler, but since the cooler is mounted under and behind the turbo, you can't really see it well. I've found that going up between the hydraulic cooler and the frame, I can get a decent view and acceptable access to things.

This is all to add another check point to everybody's list. Slide under your coaches and get a look at the oil cooler. If you're not comfortable doing that, figure out a way to get a view of the oil cooler (as if you were looking through the radiator/CAC assembly). You'll spot coolant seepage before the issue gets to be a real problem.

I'll try to remember to get a picture of the area this weekend.
