 | Subject: heating up while at hwy speed?  Mon Aug 02, 2010 3:38 pm | |
| The 95 RMW has started heating up while at constant hwy speed. I can take it out of overdrive and as the engine RPM increases, it will cool down. Could the radiator stop up like the heater core does? I installed a new radiator about 40k ago and a new water pump about 80K ago. Your thoughts please. | |

| I would suspect the water pump impeller to be slipping if this is the case. | |

| Well, rather than trial and error, I changed the pump, thermostat and flushed the radiator. Problem seems to be solved. I am going on a 40 mile trip tomorrow. I'll keep you posted. Thanks for the replies. | |
