How to burp the pony motor, gas starting engine, on Caterpillar D311, D315, D318. After draining the antifreeze/coolant or refilling the antifreeze the pony engine may over heat if the air in pony motor has not been bled out.

Interesting on my 112, the owners manual goes into great detail on how to drain and refill the cooling system but my D4 manual says hardly anything about it. Both are D315 engines just a year apart. My rule of thumb is that if you cannot get as much back in as you drained out, there is an airlock somewhere.

Testimonials

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
