Side or rear radiator diesel pusher
What are the advantages/disadvantages of side vs rear radiator on a diesel pusher?
Forum Discussion
Some bad information is being posted here. Information from people that do not have any mechanical knowledge. When somebody posted that the engine has to be dropped to work on it, that to me is a person that has just driven the coach but has no know how on how to fix these engines.
I had a exhaust manifold replaced on my Caterpillar 3126-E at Freight liner and they done it with no problem without dropping the engine.
When my coach was new I had the valve lash adjusted at so many miles and they just lifted the coach on a hydraulic lift and worked from underneath the coach with no problems.
Then some more wrong information that a coach with a rear radiator sucks air in? Coaches with rear radiators suck the hot air from within the engine box through the radiator and CAC and gets rid of the heat.
Then the post about only coaches with tag axles have side radiators. Again wrong information I have seen many commercial buses with rear radiators, side radiators and center radiators. The chassis builders will place them in different places.
The do cost a lot more because of hydraulic pumps and hoses that have to be added. And the statement that they never give problems is a laughable statement. They are mechanical and anything mechanical can give problems.
I have never had any problems with my rear radiator through 13 years. So to me even if I was to buy another coach it would not be a deal breaker. To me the most important thing in purchasing a coach is the floor plan.
