Hey everybody, sorry about posting another thread on this. It just seems every other one i start reading into they sort of go off on different tangents and stuff. soo anyways i bought an '02 liberty sport in fall with 63k on her. Ofcourse, check AC but not heat, get back from being underway and it's 14 out and my heat hardly works at all. Barely works on 1 setting, any higher and it just gets cool. So here is everything that has been done to try and correct it so far..
-Completely drained coolant
-Full flush/backflush of heater core, radiator and the block. Plus an antifreeze cleaner...my antifreeze was extremely dirty and sedimenty so whoever filled this up mustve tapped their well dry and just decided to put in mud. (antifreeze comes out like antifreeze now)
-changed thermostat, brand new (inserted correctly)
-New upper radiator hose
-New engine coolant temperature sensor
-Bleed out after topping back off.
So there's everything so far. So now i get heat up to about the third setting. 1/2 are decent and warm, but 3 and 4 sort of lukewarm. I have no radiator leak or heater core leak, heater core had good flow after flushing and same with block and radiator.
I do smell a little antifreeze inside when my heat is on, but my uncle spilled some of the antifreeze when topping it off and i don't think it's just burned off yet.
I just got back from soccer and decided to check hoses....
heater core hoses are both hot in/out
Radiator hose--only top is HOT, bottom was cold (right after i shut my jeep off i felt it), so is there still an air lock somewhere and i should try bleeding it again? maybe we didn't fully bleed it out earlier?
Sorry i jumped around, hopefully ya'll can follow what i was saying :shrug:
