Got a 98 TJ, 6 cyl. I've got a small leak in the upper corner of the radiator. I've put Bar's leak stop in the radiator and that didn't work. I've also tried cover the hole with JB Weld and it still leaks.
I'm trying to find a cheap way to patch the hole until I've got the funds to replace the radiator. Anybody know of anything I could spray on the radiator in that corner to stop the leak?
Honestly, ya just gotta replace the radiator. If funds are low, try a junk yard TJ radiator as a temp fix. None of the temp fixes will last more than a few days at most, and makes a mess for your waterpump, thermostat, and heatercore.
Look at it this way-if you think you are saving money patching it to get by-if it pops and cooks your motor-how much do you think that will cost? or it it pops and you do shut it down it time-the tow bill will be about the same (maybe more) than the cost of a new radiator. And flush that stop leak junk out, now you will be forced to flush the system before putting coolant and DISTILLED water back in.
Make sure when you add water to the coolant for its 50:50 mix to ONLY use distilled water like you can buy by the gallon at your grocery store. Tap water is high in mineral content which will eventually clog a radiator with hard water deposits.
