hello guys I have a 1995 Impreza awd wrx turbocharged from japan and its overheating. The fans are coming on and coolant is bubbling from the coolant/radiator fill tank. What I did noticed was that the top radiator hose was hotter than the bottom radiator hose(cold). So I assume the coolant aint flowin through the engine and radiator. Arent they suppose to be at an equal temperature?the car has a major over haul but I dont think they changed the thermostat. the overhaul only included changing pistons, rods, bearings, crankshaft, head gasket etc. Can anyone help me . THANKS A MILL !
