Someone using one of our cherokees when the new belt idler crapped out and they kept driving, even after I begged them to pull over and wait after they first heard a bad noise, long story but she broke just about everything in the front belt area where that idler gave out. By the time I met up with her the belt was destroyed, heater outlet pipe on the water pump had a hole chewed in it and my poor Jeep momentarily hit the high mark on the temp gauge before she turned the engine off. When I got there it would vent steam through the reservoir tank (other time I’ve seen this is BHG on another car) . This was a ho Jeep not a renix, so the cooling system is different.
After I got the Jeep home I replaced just about everything I could up front, lots of things were smashed by that damned pulley. once I was done the old Jeep ran good just like it always has. I do remember it being a pain to get the system fully burped. Not as bad as newer cooling systems, but not as simple as I remember it being, this time the block and heater core were really drained, all kinds of pockets of air.
On mikes Jeep I wonder if the block is blocked and if the cooling system is correct for renix, maybe a previous owner mixed and matched.
I’m sort of surprised there isn’t a reverse lock out, but thinking about it on those transmissions I’m not sure how it would be done.
