No in Alberta but many of the campsites we enjoy by lakes for fishing or areas for quadding are often on gravel roads, we are not camp in campground kind of people, LOL

Yeah we have no choice on the choice of roads, 95% of our camping locations are off gravel but it is noted

Yes it seems to be tight, and when it was getting hot we popped the engine cover while driving, carefully and it seemed to be pushing air, I think the radiator just wasn't clean enough now I hope it is.

Commercial Grade simple green has been my goto for years, I don't think I realized how quickly these radiators get dirty, I use to clean my vehicles once a year, but this pusher gets dirty every trip out as we tend to drive a lot of gravel roads

Thanks didn't get a chance to check Amazon yet

They actually don't make that adapter anymore I have an email into them about it

Thanks but I think I need something different I don't have an odb connector I have a six wire CAT connector for diagnostics but I will look it up online and see if it will work I have to apologize for my earlier comment looks iike it might work

Cac is sandwiched with radiator just did flashlight test could see through entire rad now The wastgate seems to operate with no sticking at all I'm beginning to wonder if it was purely heat related but I don't know till I can get it on a scanner Is there software I can buy that will aloow me to review the data, used lota of different stuff on Cummins and duramax engines?

At cold start it runs about 75 to 80 lbs, at warm operating tenps fast idle it is about 65 to 70 lbs, and running down the road it runs about 75 to 80 lbs, has for the 10k we have owned it and had an oil analysis done this spring and nothing was out of sorts

Didn't clean the Cac will check it today Head and exhaust look good viewed while running Turbo actuator do you mean wastgate, visibly looks good will inspect it for movement today Radiator is rear mounted, not sure on Cac, will update 110k miles

Solid at 80 plus lbs

Adding motor is a 96 and is a 3126 - 300hp

Thanks both for feedback, first I have reached out to several cat specific shops near me and they all are quoting me over a month before they can get me in so having a look for myself first, sstgermain because it works fine for 3 hours of hwy driving then fails and if we shutdown for a day and restart it goes another 3 hours with no problems, I can't see it being a leaking hose but I did a thorough look and all clamps, hoses are tight and I can not see any visible leak locations, I will check again however Turbo is possible I guess however why when we turn off and restart right away it works just fine for sometimes 30 minutes, sometimes longer, a mechanical failure doesn't make sense to me under those circumstances Waste gate is again possible I will check that it isn't sticking After some more reading I'm leaning towards a sensor like atmospheric or turbo boost, but appreciate. More feed back As to the service two years ago, they checked hoses, general overview, adjusted, checked valves, changed oil and all filters, fixed an oil leak on valve cover, changed belts, that is everything I see

Hello new member, we have a class a with a cat Allison diesel pusher combo I have read most of the forum cat power loss messages and they seem close just not exactly the same as what is happening to us Over all the engine and tranny run really well, however this year while we were heading on a camping trip at the 3 hr mark at hwy speeds, we got a check engine light and noticed she was a bit warm above the 190 mark, took foot out of it, the light went out but then following that we had intermittent power issues like it is limp mode, the turbo doesn't produce boost like normal Found rad was filthy so cleaned it we thought really well and took another trip and again at about the 3 hr mark same loss of power and it wasn't near as warm, parked at campsite, didn't notice big heat issues, then drove back again at the 3 hr mark started again, drove 30 more minutes home, and noticed rad area was really hot, so waited for it to cool down a bit and cleaned it really well this time The interesting thing is when it loses power if we stop turn it off wait a few minutes and restart motor it runs great again for and a varying amount of time, rinse and repeat Any ideas where to start? New filters all around start of this season, oil change this season, rad level ok, tranny level ok, tranny and motor serviced 10k ago, at cat dealer by previous owner, have documents 110k miles
