I recently purchased a 1140 CPX from a fellow in western NC that had brought several back from Texas for resell.
The RTV has 645 hours and apparently had a history of overheating.
He said his mechanic removed the head, replaced the head gasket and pressure tested - everythink checked out.
He said they determined the thermostat housing gasket was the source of leak and replaced - solving the issue.
I picked up the RTV, got it home and after a longer test ride, the temp needle pegged right.
I removed the radiator cover and saw the fan, not moving. I replaced the fan with a new one for a 96 Honda Accord, which fits perfect and blows air through the radiator well.
RTV still over heats. I notice the fan always runs and after reading postings here, I replace the sensor at thermostat, now fans cycles on and off, but of course still overheats.
So, maybe the thermostat is stuck? Removed thermostat housing and thermostat was completely missing, so i installed a new one. Of course it still overheats.
So maybe the radiator is clogged? Removed the radiator and had it cleaned. It had a small leak and was pretty clooged according to the shop. With the repaired radiator, it still overheats .
So what's left? All the hoses look good from what I can tell. Water pump? When I remove the radiator cap from the radiator, the water is hot, however i don't see any water flow.
Should I? Thinking i should replace the water pump, just because there's not much left.
Any ideas?
