I have a 2002 Mazda MPV with a rear heater and AC. The controls for the rear heating and AC are in the right rear passenger compartment just in front of the wheel well. I have noticed a coolant leak on the ground near the right rear tire. It leaks about 20 cc a day. Is there some sort of coolant line that would run to the rear of the vehicle? Any ideas/ solutions? I would like to avoid taking this problem to a Mazda dealer.
Yes there are lines that run to the back . Put the vehicle up on a hoist and just look to see where the leak is. if it’s too messy to see, clean it first. It could be as simple as a hose clamp or a spliceable waer thruogh.
