Greetings, we're back on the road again and have been idle for the last year, (setting up home in New Bern, NC from Wilson, NC). Thought we were going to sell our coach but seems there are other plans in the works we weren't aware of and are now seeing a purpose for using our RV. The last time we were out the generator was not starting well but after some time it started but then stopped after an hour of running so I figured it needed servicing. When we got back home I changed the oil and oil filter and drained the radiator coolant. When putting the plug in the radiator the plug didn't tighten and it seems I have stripped the drain. Old school tells me I need to remove the radiator and replace it. Is there any other wisdom out there hat I am not aware of? Is there a way to correct this issue without removing the radiator? Any help is appreciated, thank you. We have a 2000 Country Coach Affinity, Bed and Breakfast Model. Generator is 12.5 KWHD/CAB diesel.

Perhaps a tap with similar threads could restore the threads. Sure it's the oil drain hole that has the issues and not the drain plug.

Kevin,
Is it the radiator drain plug? Usually, they are T shaped and only open so far to drain. Also, PLEASE change your fuel filter, as that may be the reason for shutting down.

Yeah, it is the radiator drain hole. There are only three threads for the plug to grip.

Cowboy, sorry I was confused about your problem being the radiator drain and not the oil pan. Is a helicoil insert a possibility? I've used those in the past with some success.

No worries Bob. The threads are stripped and the plug won’t tighten. The hole is 3/4 inch large. Looks like I need to pull the rad out and carry it to a rad shop.
