[DeTomaso] Fw: Temp Gauge

[Will Demelo]

"""Where did you take your temp readings from?   Temps can vary widely """"

You're right. I was getting different readings all over the place. I took the reading at the very top of the stat housing. I tried to measure the coolant temp in the tank with the cap removed but it overflowed when the stat opened?? I have a 180 stat. When it started to overflow, the gun measured 180 at the stat housing but the temp gauge read 210. I have a new pump, new rad and new dual flexalite suckers. There ain't know way this is overheating.

  I replaced my leaky water pump and rad and my temp still read high. I determined with an IR temp gun that my gauge reads ~210 when it is only 180. Do these get calibrated? Can they be repaired. Do the vendors sell a replacement that works and looks original?



You could try a number of things; first and cheapest and easiest would be to change the temp sender.  Order one for a 1972 Mustang with a water temp GAUGE, not an idiot light.  That sender should be mounted on the front of the motor, NOT on the water tank (the tank is the stock, dumb location).

You can also wire a resistor in-line between the sender and gauge to knock it down some should that prove necessary, but I would be very careful to ensure the accuracy of your readings before 'tricking' the gauge.

Where did you take your temp readings from?  Temps can vary widely between the motor, water bottle, inlet side of the radiator, and outlet side of the radiator....
