Looks like I need to replace my heater core on my 2000 Sport with the 4.0. Blows a little heat not much. This is an expensive fix. Has anyone done it in their cherokees? Looks like the whole dash has to come apart.
If it ain't leaking, flush it!!!
Not leaking on the passenger side. Seems to be leaking on the drivers side.
It’s not leaking on the passenger side. Doesn’t really blow hot air and get warm in the winter. I was told it needs a heater core. Thank you everyone
I'm confused^^^.
How does a clogged heater core cause overheating engines?
. With that in mind, have a look at the heater core water flow circuit. It siphons water off the primary circuit right at the tstat housing and then returns it directly to the water pump which then sends the water through the engine coolant passages. This creates a substantial flow of warmed water to the tstat while it remains shut.
That only applies to the +97 models, how do you explain the earlier ones that have a control valve in the circuit?
