radiator in 2003 jeep liberty
I hope you are not going to add any of the block sealer to the system cause it causes more problems than it fixes, plugging up heater cores, smaller coolant ports in the engine and not to mention what it does to thermostats and radiator. That being said if you are wanting to add something like Water Wetter addictive then it should be added to the radiator itself, some vehicles you may have to remove the upper hose on the engine side and pour it in there then put the hose back on and then add the lost coolant to the recovery tank.
