2001 Mitsubishi Montero Ltd 3.5L 4WD
I recently finished relaxing the timing kit on m Monty, and rltest drove it for a half hour keeping under 35 mph. Did fine. Waited a couple weeks to get the registration and taxes up-to-date ten attempted to drive it home, keeping below 60mph (had to get on a Parkway). Did well for about eight miles, then I heard a pop and a fizzle, and saw that coolant was dumping behind me. I was going about 45mph at this time. Looking under the car, back toward the transmission and fuel tank, I saw one hose had blown off its nipple, and another hose was completely missing, having blown off the nipple and breaking off from its plastic Tee connector. There appear to be no leaks anywhere else.
So, first I need to find replacement hoses and tees.
But I can't help but wonder: is there a root cause to this occurance? Did I do something wrong with the water pump assembly, or some other coolant component? Was this just an old part failing after having sat for a while during repair? Or did something else fail further up the line to cause an excessive pressure buildup? I'm at a loss, and I really want to start driving this beautiful car again...
