My son't 87 CRX is constantly overheating.
I've replaced the thermal switch, which was bad, at the fan.
Put in the 170 thermostat but it only dropped the max temp for about 10min.
It's almost like the water pump is not pumping although I've got LOTS of pressure on the hoses.
Could the radiator be clogged up?
Is there anyway to clean this without taking it out?
I've drained and flushed repeatedly. As well as raised it up on ramps and vented throiugh the vent at the top of the engine......
thanks in advance
