2002 Mazda MPV Q&A
2002 Mazda MPV Question: coolant of color green is leaking at rear and at next to rear wheel?
I would suspect that your vehicle is equipped with rear climate control. If so, then I would strongly suspect that the rear heater core is ruptured and leaking. A cooling system pressure test must be performed to verify. - Brian Glastetter
THERE ARE COOLANT LINES GOING TO THE REAR HEAT CORE. BEFORE CONDEMNING THE HEAT CORE, HAVE A COMPETENT TECH PRESSURE TEST THE SYSTEM TO DETERMINE THE SOURCE OF THE LEAK - Villageauto
Man i had same issue, the oldest vans with rear heat equiped they used metal tubing for coolant and that fail after few years. Stupid manufacturs!!!!. Now they using aluminium lines which last life time. Its actuly two parts from engine to middle of car and from middle to rear heater core another.I made my own line if your a handy man you can make line with cooper tube. - geojose
