Need help ? 2005 mazda mpv overheating after change water pump and thermostat. ....
did someone PANIC and refill with hose water after steaming and leaving the underside of the hood all discolored...this motor is cooked..could try taking the thermostat out all the way and repeated coolant flushes but aside from that the block is clobbered with rust~
Make sure that the thermostat is in the correct way, not in backwards. MPV's are one of those rigs that have problems getting air out of the cooling system, try this cold, elevate the front end and take the radiator cap off squeeze the lower hose carefully from block to the radiator then do the same thing with the upper hose, start engine and watch the level, when it drops refill it, keep adding coolant until it stops dropping, reinstall radiator cap then add some coolant to recovery tank to full mark. Run engine at 1500 to 2000 RPM until it reaches operational temp, let the engine idle and watch for overheat also watch for cooling fan operation.
