2000 Mitsubishi Diamante LS 3.5 V6 from North America


I have received more value than one could expect, based on the price I paid for the car


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.

Heater core is the death of this car!!!


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.

The car was made in Australia so they just bypass the heater core as no one uses the heater anyway.

Overall - a reliable car if you do not get stuck with the heater core issue.

Not a disappointment


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.

2000 Mitsubishi Diamante SEi 3.5 V 6 from Australia and New Zealand


Great car, nice ride


Totally perfect; everything works.

When I bought in October 2005. I received all service records; it was an ex company car.

I replaced all fluids (oil, transmission oil, water and brakes), fitted new pads all round, the rears I believe were original. In NZ our cars are tested each 6 months; my tester says it is mint.

I love it, it's the best car I have owned.

I still have my 9 year old Daewoo wagon for a runabout and shopping, but wouldn't go on the highway, no way.

General Comments:

The Diamanti SEi is Australian built; it's heavy on gas around town or towing.

But come to a trip, it comes into it's own, cruise at 100 or 105km's, and the computer shows 9.7 ltrs per 100k's with the air con on.

The cruise control is better than a Playstation.

Power for passing is first class.

I cannot believe the negative comments on these cars; two friends have older ones with high Kms and they love them too.

Love the leather, the sound system, the big boot (trunk).

This was a $50K plus car new in 2001. I paid under $10k in 2005; what a deal.

Most of the negative comments about the Magna/Diamante come from people in the US, not Australia or NZ.

The single biggest complaint relates to leaking heater cores. Never heard of this problem here in Australia. It might have something to do with the severe winter weather common in the US that we are fortunate not to have with our mild winters, so the issue of antifreeze and heater cores is not much of a problem in our part of the world.

The only problem I have had with my 1999 Magna that is common to the American drivers complaining, is that of the antenna breaking. In my case only the mast broke, but my mechanic ordered one in and the next day fitted it in 10 minutes, total cost $50.

Overall, little has gone wrong with my Magna in 2 years of ownership. A pleasure to drive and excellent value on the used car market. You did well for getting yours for under $10K.
