I have been struggling with a problem with my 120 for quite a while.
It blows coolant overboard. It does NOT overheat, not even close.
But it has popped two upper radiator hoses, and one bypass hose at
the T stat housing.
With the engine at operating temp. (160 stat), rev the engine to
over 3500 & I can see the upper radiator hose bulging. It has blown
the top radiator hose off of the stub on the T stat housing, with
predictable results. Bypass hose is normal
The water pump is a new manufacture unit for a 120 that is now
perhaps several years old. Been doing this type of behavior for
Today, I took the T stat out, re-assembled the housing & the
problem is gone gone gone. This tells me that the water pump is
more energetic than it needs to be. T stat is a bypass type non
bellows unit. Other t stats have been tried with similar results.
Anyone else have problems similar to this with a non-original water
