I have a 1995 Mazda MPV and it keeps overheating every now and then, especially when I use AC/Heat, but the radiator does not get hot at all. It's not leaking anti-freeze & the thermostat is new..
the themostat may be faulty from new or incorctly installed. also there could be a problem with the water pump air in the cooling system could also be the cause but this is a bit less likely.
