Three problems related to radiator have been reported for the 1999 Mazda 626. The most recently reported issues are listed below.
I bought a 1999 Mazda 626 lx in November of 1998. VIN 1yvgf22c3x5825750 about the time the warranty ran out I had taken my car into an oil change franchise. They suggested that I flush and renew the transmission fluid. So I did. That's when all the problems began. I then drove the car from NJ to FL where I lived. It started burning up a lot of oil so I took it into to Mazda. They said that it was well known that my make and model car runs hot. They said they could not see anything wrong with what the oil change franchise did. They recommended that I put a radiator on the transmission to keep it from boiling. . . Which is what it was doing. I believe it is the boiling transmission which has cause my engine to heat up so much that the oil has gunked my engine. Anyway, I took the car to a mechanic and they put in a radiator which seems to help some but now I'm continually having problems with the oil burning up without there being any leaks. I have continually had problems with the vehicle every since. In and out of the shops. No one seems to be able to get the car right. I have seen numerous reports of other Mazda owners having problems of this similar nature on the net. Mazda should take care of these problems and admit publicly that they've got problems with their vehicles and they should make it right.
1999 Mazda 626 ES v6-purchased used in 2003 and have had a continuous problem with overheating. The vehicle now has 85,819 miles on it and continues to overheat and now the a/c blows warm air even after replacing the compressor and switch. We have replaced the thermostat, relays, fans, water pump, flushed out the radiator, front and rear gaskets, new air compressor and have spent about $2500 in repairs only to be told by the mechanic he is out of options as to what is causing the problem. I believe Mazda is aware of this situation since I am reading on the internet various complaints about all of their products and see a pattern with the problems and these vehicles. When you purchase a vehicle and expect it to be reliable transportation and it is your only transportation it makes it impossible to replace since their is a contiuing problem. Mazda needs to be held responsible for these vehicles and held accountable for these repairs.
I am the original vehicle owner. The car has 120,000 miles on it. I had to replace the radiator, oxgen sensor and the transmission this summer. It seems unusual for a car this young to have such extensive, expensive problems.
