Help! Winter is coming and I have no heat!
Hi I have an 89 YJ that is pumping cold air but the temp gauge is
reading 210 degs. I just change the thermostat hoping to fix the problem but still having the same issue. I think that there is either a clog or air lock but I'm not sure how to test it or fix. I was thinking of flushing the system but have never done that on this vehicle before. I've run the car with the radiator cap off and did not see any circulation of fluids. I also noticed that the hoses going and coming out of the firewall are cool. Any help is appreciated. |

The passages in the heater core are smaller than a radiator's. You can test this by running one of the hater core hoses to the other connection on the engine. If the hose gets hot, then you know the restriction is in the core. If you do need a core, I would take the Jeep to a reputable shop that knows how to correctly flush a cooling system and have it flushed when you put the heater core in. For the future, I recommend using distilled water in your cooling system whenever possible (with antifreeze of course). This will cut down on the calcification that causes the heater core to plug up. My friend has a radiator repair shop and charges about $45 to flush a system and put in fresh antifreeze, so it shouldn't be too expensive to have it done where you live. Chris |

I am having the SAME problem on my CJ-7. Do you guys know if I have to take
the dash completely off to access the heater core?
