I drive a1997 Ford Windstar (against my will) the temp gauge will start out dead cold than climb to almost red hot than drop to cold again within 2 blocks, there is more than enough anti-freeze in the resivour and plenty in the radior itself. It burns it thru a small leak on the back side of the engine. I think its the water pump or thermo but I cant get to them my parents say to leave the cars to a professional. If you have any ideas Please respond

 

This should cause no other problems, but could be a risk in terms of a person getting used to it showing low and not paying attention to the oil level. Since the rotary injects oil as part of normal operation, it consumes oil. When the gauge works properly, it is easy to note small changes in level by looking at the pressure. If the gauge isn't working properly, then it may not be easy to identify these changes in level. So if you choose to live with a bad pressure sender, check the dipstick REALLY often, at least once a week. also

I wonder what this has to do with a coolant leak.[sm=oopssign.gif]

 

I would think that you have a problem building. You might not have enough coolant in this motor, and knowing this motor, it doesn't like that. They have a tendency to lift head gaskets. I would find the source of my leak and fix it. [sm=mail.gif]
