Dart over heating???

Oh boy here we go again.

Don't change the thermostat temperature, The only thing a thermostat does is keep your car from running too cold. Lowering it does not increase your systems cooling capacity one bit.

There are higher flow thermostats that may help, but I would not change the recommended temperature.

Ok then. Put in a 195° thermostat and see what happens.... At least you will have less engine wear until it overheats (you will have a 35° head start to get there)... LOL.

Like I stated in my first reply. Put in the shroud and seal all gaps with foam between the shroud and radiator. Your problem is that you are not pulling enough air through the radiator at idle and low speeds.

You need a good fan, a shroud, and to get the air to flow through the radiator, not around it.
