OP
What did you do to bypass the system? Any info given would be greatly appreciated. Why did you choose that over the barr tablets?

 

I disconnect the the hoses from the heater and make a U with one of them to connect both pipes to by pass the heater.
I had a new thermostat so I was not worry about it so I kept the old one and replaced it when I finished with the procedure.
Just an update. I'm still running with out a problem since I did it (more than 5k miles)

 

How many miles on your engine? Do not you K Seal do a proper coolant pressure test and repair to fix your coolant leak or you risk loosing your engine.
Make sure to flush and refill your engine with distilled water and coolant so you don't build up more calicum.
Also replace your t/stat with a 180 t/stat and pressure cap to help the engine run cooler.

 

For what it is worth, never disconnect the heat by rerouting the hoses, this can cause the system to overheat as the heater core is part of the cooling system

What I did was over passing heater only for one day while
I was running the engine with the KSeal since I did not want to get it in the heater. I was monitoring the temp during the time.I flushed the system after one day with the K seal and changed the thermostat.
I'm not a bit believer of Kseal and I only did it to buy some time until I can have the time and money to get the hg done. Again I have put over 5k miles since I did the procedure and it is still working (meaning no loosing coolant)
