CRF450 to CR500 radiator hose issues
Posted: April 20th, 2014, 2:48 pm
We just tried to connect the radiator hoses and I have some issues. My chassis is a 2007 CRF450R.
I welded a new outlet on the bottom of the right radiator that goes to the engine water pump. It works fine.
I also welded a new 90 degree downward inlet to the top of the right radiator for the right cylinder head cooling hose. That works fine.
The CRF450 has a crossover hose on the top of both radiators. The original CRF450 hose works fine there.
Now the problems:
1. The CRF450 left radiator has a hose outlet on the bottom left but no matching inlet on the bottom right radiator. The original CRF450 bottom left hose angles slightly downward and went into a 3-way fitting instead of crossing over to the right radiator.
2. The original CRF450 upper left radiator hose 90 degree inlet is a slightly larger size and the CR500 hose that comes from the left side cylinder head will not go over the CRF450 radiator fitting.
Does someone sell the 90 degree aluminum hose bib fittings I can weld to the left radiator without having to sacrifice another radiator?
How did you guys tackle these issues?
