I would doubt the thermostat has anything to do with it. If the thermostat is stuck closed it will overheat sooner than later. Joey indicates that 1. This started after the motor was fixed; 2. Upon deceleration and idle. To me, that would indicate that it is somewhat rpm dependant as well flow dependant. One would think the fans would not be kicking on unless it was already overheating while decelerating. If this were my car, I would start at the water pump, after doing the easy stuff such as verifying coolant level and checking for an air bubble. The water pump is affected by flow and rpm. The second place I would look is the radiator. How new is the radiator? When was the last time a good flush was done? The last place I would look is the motor. Does it have the correct head gasket, etc? It could be the higher coolant temps have caused damage to the motor once again.

Thanks for the responses. Both fans work. Water pump is new. I blew the head when I over revved the engine after getting stuck in a ditch in October. There are no leaks. Coolant level has remained steady since the repair.

It over heats every time I take my foot off the gas. So if I'm going downhill on the highway and slip into neutral I will see the gauge start to go up. It heads straight toward the top and rather quickly. Sent from my iPhone On Jun 8, 2012, at 11:51 AM, "Bill Cardell" <[email protected]> wrote: I'm a little confused by your description. If you are cruising at 60 and take your foot off, does it get hot? Or do you mean it overheats any time you stop, rather than any time you take your foot off the gas?

After long drives on the highway and ONLY when I take my foot off the gas, the gauge shoots up. So I go on a long drive, pull off the highway and sit at a light and it starts heading toward the top pretty quickly. Step on the gas to go at any speed in any gear and it drops back to normal. Is this a bad thermostat or something else? Background - This is a 96 Miata. I blew the head and had it replaced by a friend who's a mechanic. Works pretty fine except the engine is a little loud and now this heating issue. Suggestions? Thoughts? Thanks in advance! Joey
