“Around jan 2008 while driving a plastic water hose burst. I replaced it and had no other problem until around aug 2008. This time the water pump started leaking. I replaced that and the thermostat and radiator cap, but I still kept loosing coolant. Then I found a crack in the radiator which I replace around the end of aug 2008.

I was told that we had already taken the car in for the recall, but I didn't recall doing that. …”

“This car belongs to my elderly mother which she bought used and has been an on going problem! Occasionally when starting the car, the engine will backfire, after starting it would run ok. The car now does not run as the intake manifold is broken from the backfiring and almost caught on fire the last time it was attempted to start the motor!
