'96 Taurus/temp fluctuating

Any suggestions from this elite group most appreciated. Temp. reading fluctuates on 1996 Taurus, just installed a different 3.0 engine.. To: "Ralph Griffith" Subject: Re: Taurus Date: Thursday, April 22, 2004 10:53 AM

It's good thinking. The mechanic did that first thing after he put the engine in.

Strange thing is after running for about an hour - if I have the heat on - the heat will go down to where its just putting out fair heat. If I rev the engine the heat will get back to the temp it is supposed to (hot).

Indicates to me either a water pump not pumping adequately at low rpms or maybe air in the system causing a slow down / stop in circulation.

I'm going to run it for awhile and keep putting water in to see if it is air needing purging.

Strange problem.
