My 2001 mitsubishi diamante's heater core went up. I have massive amounts of coolant leaking on my passenger side, thick smoke coming from my vents and a bad odor coming from the vents. I have read this is a very very common thing with mitsubishi's especially diamante's.

What owners say
My car is making me sick!! I noticed a smell of anti-freeze coming out of the climate control vents. Upon further investigation, I noticed anti-freeze/engine coolant leaking from the heater core down onto floor mats, climate control intake, electrical wiring inside dashboard, and more importantly automatic transmission computer. This is a significant safety and health issue and needs to be addressed immediately. Where is manufacturer's recall.

Purchased 2001 diamante in september 2004. Had approximately 66,000 miles when purchased and approximately 73,000 miles now. At the time I purchased the car, I noticed a maple syrup smell in the interior, but I didn't know that it was an indicator of a problem so I didn't mention it, I thought it might be a cleaner that was used in the car. In december 2004, brought car to mitsubishi dealer where car was purchased for a routine oil change and tire rotation. Was informed that strong coolant smell in interior (maple syrup smell) was from a coolant leak caused by broken o-ring which I was told by the service manager "happens in almost all diamantes". I told them that the smell was in my vehicle when I purchased it from the dealer in august and I believe they were aware of it at that time because they were able to quickly identify that same odor when I brought the car in for service. I have asked the dealership to pay for the repair since it is apparent they sold me a defective car. I have not resolved this issue yet with mitsubishi so the repairs have not been made as of the date of this report. Currently the symptoms of this coolant leak are consistently and severely fogged up windows (all windows of the car) making visibility difficult. I am also quite concerned about the health consequences, including respiratory problems, I am facing from inhaling antifreeze fumes for the last 7 month which are only getting worse.
Heater coil replacement. Causes car to overheat, also causes bad smell and heat and fumes to come out of the dash. It has come to my attention that a large amount of mitsubishi diamantes up to year 2001 have this problem and it has not be considered a recall. I wanted to know why and how this issue can be fixed. It's not fair that customers have to pay over 1000. To get something fixed that is obviously a manufacturer problem. This is not an optional fix since it can ultimately cause an engine fire.
Coolant leaking into rug on front passenger side, coolant fumes leaking from air vents, constantly adding more coolant to car, foggy windows that would not clear up even after an hour of driving, scent in car that kind of smells like syrup. Constant headaches, nausea when driving inside vehicle, hard to drive due to foggy windows. Took car to dealer and had heater core replaced. Faint scent of syrup still remains in car.
