Searching...
I did some searching... Tried a few things, still have slight problems.
So, since you asked!
She had no heat,
1 Was a little low on coolant-filled-slightly better
2 Flushed heater core-came through clean, both directions. Pushed air through also and is free flowing. No change
3 noticed small leak in radiator-new radiator-slightly better
4 changed stat-again slightly better

So adding it all up, went from cold, no heat to warm, but doesn't get hot like my truck.
Gotta look into the blend door, next...

 

Start out by telling us what year , engine and model you are talking about.

 

If you're getting your stats from anywhere other than the dealer at this point, that COULD be the problem. What's the temp gauge read when fully warmed up?

 

99 Cheorkee classic 4.0 temp is about 195/200

 

That sounds about right. How do the hoses feel by where they attach to the heater core. Is it possible that the metal tube coming from the water pump is clogged inside? If both of the hoses feel really hot at the core then its possibly a blend issue.
