Yep, another heater thread...

Got my jeep back in June, not my full time DD, but I was missing it in the winter so I threw the top on and took it out.

the PO is a friend of mine and I knew the heat wasn't really working. The fan works fine, the blower changes at every level, ect.

It's more like a heating issue itself. I'm thinking the lines are blocked somewhere, but does anyone have any experience clearing them? Step by step would be great.

I don't really want to replace the heater core as that is a real PITA.

Thanks!

Drain your coolant and shove a hose in the radiator fill hole, after a few min replace with new coolant and a water pump conditioner and see how she does. Itll cost you coolant/conditioner and a few minutes.

Real easy!

Grab two grip-pliers or wine bottle corks. Either will work believe me =)

Pull the two heater core hoses off an plug them up. Either by pinching it with the grip pliers or shove the cork in there. Grab a hose, put it on where the lower hose goes and blow water through it until it comes out clean.

Repeat the process a few times and plug it all back up and enjoy the heat. =)

Worked out for me just yesterday!

What I've heard is best is to BACKflush the system...I've been told if you flush a clogged system, sometimes you'll just shove the clog further into the heater core, whereas if you BACKflush it it will push the clog backwards. And if you have any experience with clogged up hoses, you'll know that typically it's easier to unclog one by sending the clog out the way it came from instead of forcing it further down the line until it widens and pops out (or just gets uber stuck).

I have a '97 4 cyl.

What size are the heater hoses and which one do you attach the garden hose to to back-flush?

Thanks
