Hubby had just finished putting new hoses from the heater core to the engine (the old hose was leaking) and was quite careful about it, didn't tighten too tight etc. Turn the car on and after 5 minutes of running the upper hose broke just past where it was clamped to the plastic from the heater core so coolant is spewing everywhere. He thinks the heater core needs to be replaced now. And to top it all off when I pulled it back into the garage I was too far over and hit the end of the engine hoist with the passenger tire and popped it. The tires were almost new . So hubby doesn't particularly want to take apart the dash so tomorrow I suppose will get it towed to a shop to replace the heater core.
