I have a 2000 Diamante Mitsubishi that is failing to provide me with heat. The heat core was replaced in 2009. When the heat dial is place at every level, the air ratio increases and just blows cold air. Oh, the air conditioning works fine.

Can anyone tell me what the problem is and where I need to go to repair the problem, so I can get some heat in my car? It is cold out here. The seat warmer is working fine.

In addition, my Traction Control (TCL) just illuminated; should I take it to a dealer or can I fix the problem myself? The car has over 109,998 miles on the odometer.

General Comments:

I had the car since 2000, and I am the original owner. Since purchasing the vehicle, I have invested a vast amount of money for maintenance, and so far, it has paid off for me. The problem I am experiencing is something that comes with age. The older the car, the more attention it will require from time to time.

The good thing about being the original owner is, I am able to show proof of every bit of maintenance that was done on the car. I have a 2 1/2 inch binder, where I keep all of the receipts of the work, which was completed on the car, a historical file. This way, I am knowledgeable as to what needs to be done, and when it needs to be done.

I would recommend the same approach to every new or old car owner; start keeping your own records.

Seats are starting to wear badly.

Same problem as most people that have this car - HEATER CORE leaking for the second time. WOW, how can they make a car with the same issue and not be recalled?

Other than that, the car is really good, reliable, and no other problems.

Faults:

Power antenna mast at 60,000, did not repair.

Heater core leak at 65,000, used Leak Stop to fix.

Standard maintenance on timing belt at 100,000.

Small leak at oil pan at 150,000, used Leak Stop to fix.

Runs strong, rides good with 1 or 2, changing rear shocks now for heavier ride comfort.

Changed the oil regularly at 3,000 miles, engine now starting to smoke slightly at lengthy idle on very hot days.

General Comments:

Had 94' Diamante, it smoked heavy due to valve guides wear at 200,000, the 2000 model is doing much better. I would consider buying another if made in Japan, but not in Australia.

Thanks to all those who sell parts on Internet, Mitsubishi is charging too high a price for replacement parts due to car model discontinuance.

Heater Core gasket, (common problem)

General Comments:

I have owned this car for two years and I still really like it. It has plenty of power (V6), handles well, and is just plain fun to drive. It has a certain "X" factor, a bit of soul, which is unusual for a Japanese car. Great commuter. It's been totally reliable, except for the heater core gasket problem, which is pretty common. The resale value is pretty low, which is bad if you bought it new, but good if you buy it used. If you are looking for an Accord or Camry, try a Diamante, MUCH more car for less money.

Problem after problem : (

The last one is the famous heater core leakage problem

Just google for "diamante heatercore" and you will see

It is a known problem and Mitsubishi knows it, but doing nothing about it. Costs 700-900 to repair or you will be poisoned inhaling antifreeze. And the 60k service costs normally 1500 for a car not worth 9k. Never again Mitsubishi.
