I recently replaced the Radiator on my 98 RR after the water pump failed. While I was at it I changed the Thermostat too.
Now I'm getting a strange over heating problem.
After driving about 30 minutes at normal speed and temperature the water temp gauge heads for the hot side. After three short trips to test it I've noticed the heater changes from hot air and starts blowing cold air.
This morning we drove 20 miles and stopped to drop off some food for friends. the air temp outside is 40 degrees, so the heater was working great. The suddenly I feel cold air blowing on my leg from the heat vent and look up at the engine temp has started to move to the fight toward hot. I cut off the engine before it overheats and I let it stand for 20 minutes.
I can restart the engine, the engine temp is normal and the heater vent is blowing hot air again. Twenty minutes later and 20 miles it starts getting hot again and the cold air is coming from the vents.
I need some help with this mystery.
