It was back in October I posted on here that I had an overheat. It seems my thermostat stuck and radiator cap failed to release the pressure and blew the seams out of the tanks on the radiator. The radiator shop guy said he sees this all the time on grain trucks and combines that sit for extended periods without use. My coach had sat for several years before I got it last year, and I never replaced the either the cap or thermostat, $15 that would have been well spent. Lesson learned for me, but something for anyone getting a sit around coach to think about.

Anyway, I got the radiator back in, lines all hooked up, and it finally got warm enough here (working outdoors) for me to get things going. I "may" have dodged a bullet, as I ran it a good hour yesterday, got the engine warmed up good, and everything seems ok.

The radiator shop guy said drive it and forget it, just watch the fluid level to see if its using any coolant. He said I am lucky its a 403 and is very confident in its ability to withstand the high temps. He's and his pops are rod builders and sprint racers after work.

I'd be interested in your guys' take.

Question: Should I have an oil analysis done, and if so, after what amount of time/miles? (it was a fresh oil change the day before the overheat, maybe 30 miles on it, so I went ahead and changed it to make sure there wasn't any coolant in it)

What would you do at this point to regain some level of confidence? Appreciate your advice.
Thanks,
Galen
