Draining my heater core.

Hey guys, any help here appreciated. I have a 4.0, manual, five speed, 98. I can't for the life of me find the drain plug for the bottom of the heater core. Any one poi t it out to me on a pic? Feel really dumb asking this but I have used my paynes manual and the FSM. Just can't seem to find it. O also I am right hand drive, so if you say it's on the drivers side of the engine please bear this in mind.

Thanks.

Yup, what he said.
Both hoses are at the front on the engine - one is clamped to the thermostat housing, the other is down near the sparkplugs - clamped to a pipe which comes off the water pump.

The heater core itself does not have a drain plug.

K your asking about the heater core, then talking about drivers side of the engine. Do you mean the rad? Because the heater core is mounted in your dash with the inlet and outlet tubes coming out through the firewall, in your case they would be on the left side. If you mean the rad then there should be either a copper or red plastic drain tap put into the bottom plastic housing. Like Wesboy said, the heater core does not have a drain plug.

Carp, yes I mean the Rad, sorry. I do need to backflush my heater core and now seeing just how easy it is I will do that.
I can find the plug on the bottom of the radiator itself. It's the second one I can't find.
Sorry again.

Have you actually got down on the ground under the front of the Jeep and looked up at the radiator? You should see it.
