One of my co-worker's had a new thermostat installed in his wife's car by a local auto shop and they installed it backwards and the engine overheated. It's a good way to crack a head. Hal

Sometimes it helps to drill about an eighth of an inch hole in the thermostats to prevent air locks and overheating.

i'm not too familiar with 70 series tractors,( mine are all older), but is it possiable to put the thermostats in upside down? that may be something to check.

dont know if its possible but could the thermostats be in backwards? check radiator cap to see that it is rated for the correct pressure and holds it properly.
