My Eagle, with an 8V71, came with no block heater, which is needed in midwest winters. The area Freightliner shop could not loosen the water jacket plug on the engine to replace it with a block heater.

They ruined a couple adapters trying to get the plug loose and even used a torch on it, saying that was the way to loosen it. I thought heat caused expansion, but what do I know?

Any thoughts on how to free the plug so the block heater can be installed?

Thanks for the advice.

FORGETABOUTIT,
and find a different style heater that goes into the block under a plate with 4 bolts.

I got my JEB 1500w from US Coach, and it went in with no strain.

There's something about truck shops.... they just don't like
working on buses. Isn't there a bus garage someplace near you?

Did you try to remove one of the other three plugs? I'm about to start on the same project and found that the 8V71 has a plug on each end of each bank.

Heating the plug will expand the plug however as it cools again the plug contracts. This action of expantion and contraction fractures the rust around the threads and helps loosen the plug. I have used this method hundreds of times working on atique equipment when heating the surrounding threaded area is not feasible. It dose take more time and patients as the plug may have to heated and let cool several times.Do take care not to heat the plug to a molten state. Best of luck. Tim

Dont be afraid to soak it with agood penatrating oil (i use Gibbs) and smack it a couple of times with a hammer. Patience!!! soak it again later and yet again, then try the torch.
