Sorry, have to disagree on the shutters thing. I’ve had them on both my coaches and they were a pain. They also block some of the much needed air flow needed to cool my 500 hp. My tstats work perfectly to keep my Bus at 180 degrees even when it’s below freezing outside. Every single diesel car and truck on the road today uses a thermostat to maintain engine temp....no shutters in front of radiators. To each their own, but I tossed mine and haven’t had any issues in 8 years of fulltiming even up north in -22f temps and 20,000 miles a year on the Bus. Sent from my iPhone using Tapatalk Pro
My fans don’t have a fan stat. They are operated by a belt and pulley off the crank. Sent from my iPhone using Tapatalk Pro
6-8 hours of idling. I thought that was really bad for our two strokes. I never really idle. But I would imagine it wouldn’t reach op temp at idle so maybe the shutters for that.
