Heater hose coolant return tube

In a 1993 jeep grand cherokee. Can I just take the mounting bracket off the tube to the block and pull the tube from the water pump--replace the o ring and put it back in? Or do I have to remove the water pump to replace the o ring?

Yes you can remove the tube if its a V8. If its an inline 6 cylinder you have to remove the pump in order to repair the heater pipe.

Why is my 2003 Jeep grand cherokee leaking coolant?

Have 2004 jeep ckerokee and ac smells like antifreeze. there is water coming out of drain hose and out of bottom of the heater core cover onto floor. do you thing this is a heater core problem.


If there is coolant coming out then YES, try blocking the heater hoses,(disconnect at the engine and loop it back to the other heater hose outlet on the engine) this way you can be sure it is leaking.
To many times removing from the heater hose from the heater core inlets will break the inlet tubes.
