1996 Mazda 626 Q&A
1996 Mazda 626 Question: Engine overheats every 400-800 miles.
at first had a leaking coolant problem...replaced radiator and temp gauge. still leaked so replaced all hoses. now no leaks but still overheats. sometimes temp needle will point to hot at stoplight then when resuming driving needle moves back to middle/normal temperature. this occurs sometimes when i drive uphill also! - woods_elijah
you have said nothing of the thermostat which is the most important piece. the fact you have driven it overheated may have done internal damage to the motor. have s hop do a leak down test to make sure the head gasket is not cracked. Roy - mastertech6371
