ON AT LEAST FOUR OCCASIONS, AND UPON STARTING THE VEHICLE, THE ENGINE, AFTER 10 TO 30 SECONDS, RAPIDLY ACCELERATES TO 4,000 - 6,000 RPM. THE ONLY WAY TO RESTRICT THE RAPID ACCELERATION IS TO SHUT THE ENGINE OFF WITH THE IGNITION KEY. *JB
AT 37,092 THE THERMOSTAT FROZE, BLOWING THE RADIATOR HOSE. AT 52,058 ANOTHER THERMOSTAT FROZE, BLOWING THE RADIATOR. WAS TOLD BY JAGUAR SERVICE THAT THESE FREEZE, AND I SHOULD BRING MY JAGUAR IN EVERY 16,000 MILES JUST TO BE CERTAIN. WHEN RADIATOR HOSE BLOWS, NO TELLING WHERE WE MIGHT BE AND SITUATION COULD BE DANGEROUS. *NM
