So this is my first post. Hopefully it's in the right thread. 2001 Grand Cherokee V-8 4.7L
Anyway, just took it in and found out the heater core needs replacing. Labor is estimated at 7 hours, but the mechanic said probably 7-9. He also said that they can replace the evaporator without any additional labor, so there's that as well. I don't have a written estimate yet, but when he called he said around $800 before tax.
I was wondering if there were any short term fixes that could be done while I scrounge up some dough. Can I just disconnect the hoses or block the hoses to the heater core temporarily so that it doesn't leak through the heater core?
Is there a way to reduce the leaking of the coolant? If i reduce the pressure by loosening the radiator cap, will that help? Just like a half turn so that it's on, but not fully on?
Any issues with using water instead of coolant? After I fill it, it takes about 5 days before the low coolant light goes on again.
Also, if anyone knows a good Jeep mechanic in the Milwaukee area that would be great. I go to this place by my work, but they don't necessarily specialize in anything. They're great, but maybe a specialist will have an alternative solution or something.
As others have said you can just by-pass it for now. But I can tell you from experience, when you by-pass the heat the summer goes by real quick and it will be snowing and you won't have it done yet. Some prefer to disconnect the hoses at the water pump and by-pass it there and thats a bit easier than taking them off at the firewall. But I would do it at the firewall because they have to come off there anyway to change out the core.
