THE COOLING SYSTEM IN THIS VEHICLE HAS A TWO PART PERFORMED HOSE THAT CONNECTS THE ENGINE COOLING SYSTEM TO THE CABIN HEAT EXCHANGER. THE TWO PARTS ARE CONNECTED WITH A PLASTIC JUNCTION WITH TWO SPRING CLAMPS. THIS VEHICLE HAS APPROX 85K MILES AND STILL HAS THE ORIGINAL COOLANT. THIS JUNCTION DISINTEGRATED. IT APPEARS TO NOT BE COMPATIBLE WITH THE COOLANT. IT DELAMINATED AND SHEARED. LUCKILY IT BROKE WHILE STOPPED IN THE GARAGE. IF IT HAD HAPPENED AT HIGH SPEED IT WOULD HAVE SPEWED THE COOLANT AT THE REAR OF THE ENGINE, AND AT LEAST SOME OF IT WOULD HAVE GONE TO THE WINDSHIELD, OBSTRUCTING THE VIEW. I HAVE SAVED THE DISINTEGRATED PART.*DT*JB
THE VEHICLE WAS IN MOTION AND WOULD NOT ENTER 3RD OR 4TH GEAR. WHEN I BROUGHT IT INTO THE RETAILER THEY SAID I NEEDED TRANSMISSION VALVE BODY REPLACED AT A COST OF $3000. THE CAR ONLY HAS 55,000 MILES ON IT. WHAT WOULD CAUSE THIS?
