Radiator Repair

I have a leak in the radiator and in the heater core (antifreeze leaking down firewall) on my '84 CJ7. I plan on removing them. Is it worth getting them fixed, or throw them away and buy new?

Thanks

My experience, is to buy a new radiator, well worth the money at a radiator shop and cheaper than online places. As for heater core, go new. Also since your there, might as well rebuild the blower motor with a chevy upgrade. Remember to use all new hoses and clamps and take your time, should be good as new.

The firewall leak is normally the hose or clamp, not the heater core. The heater core is a long ways away from those outlets and leaks onto the floor inside when bad.

If you are going to change it, i highly recommend you get the big GM blower for the squrirrel cage blower. It fits right in and puts out more on low than the Jeep one does on high. Just look for threads on the Blazer blower motor.

I recently took my rad to a local radiator shop and they recored it for me using some new tech cores that allow 30% more cores per row. Well, it dropped the running temperature by close to 30% also which was really nice. (I have a winch and lights up front interfering with flow.)

The re-core cost close to half of a new rad.
