All of this is because your sender is the wrong place.

De Tomaso stupidly put the sender in the water bottle, instead of on the 
engine where it belongs.   All other Ford cars had the sender mounted on the 
front of the engine.

At the end of the day, you don't give a damn how hot the water is in the 
bottle--what you care about is the temperature of the engine.

Back in 1989 when I first bought my Pantera, a week later one of the water 
hoses came loose and all the coolant leaked out.   The temp gauge initially 
went up, but then it went back down again, leading me to believe that the 
problem had resolved itself.   Then the motor started to self-destruct!

The sender on the bottle was reading ambient air temperature.   If it had 
been on the engine it would have read accurately and I would have known to 
stop.

Move it where it belongs--the good news is that the stock wire will reach 
without modification.
