    It is an 87 dodge dakota with a v6. i replaces all of the large collent hoses along with the therm and gasket. put in a new red cap and then flushed out the heater core twice. i did drain the entire system and put in all new coolent. it does not over heat, just wont blow hot air. the heater core does not leak

    I hooked up my hose to both hoses going into the core and let it run on each hose for about 5 mins. water came out clear.

    when i disconnected the heater core lines today before i flushed it, clean anti-freeze came out. If it is the water pump, wouldn't the truck itself over heat or leak?

Check for poor flow to heater core-change heater hoses -check for lime build up at intake connector or worn out water pump -if you only put water through core try using CLRlime cleaner in core-get two 6in pieces or heater hose hook them to core and pour it in and leave for 15 mins then wash out with water hose

The heat is only produce if the coolant flowing through the heater core. If there is no heat then coolant never flowing through due to the valve controlling the coolant passing through or the heater got clogged up. The valve is controlled by the cable where you want more or less heat. Did you actually hook up the adapter flushing only the heater core to see water passing through the heater core?

Will flushing the radiator improve the heating


Flushing the radiator should actually cause your motor to run cooler, because the flushing process removes built up gunk and rust that plugs them. If you are talkin about getting more warmth to the interior of you pick up through the heater. there are a couple things you can do. replace the engine thermostat with a little bit higher temp. or you can try to backflush the heater core itself. if you are not getting the heat through your heater the best bet is the heater core is pluged, this is very common to have happen. Hope this helped you out.
Thanks Aaron

No heat in the cab. Replaced thermostat but that didnt fix the problem. Inlet hose to the heater core is hot but the outlet hose is barely warm when the engine is at operating temp. Clooged core?


Smiley,

You definitely have a clogged heater core, unfortunately those things get clogged with sediment and it is better to replace them then to clean them out. Since you have a truck the core should be easy to access. In most cars you have to remove the whole dash. I would recommend replacement as opposed to cleaning or flushing, as most sediment that builds up in the heater core is the inner coating of the core itself which has worn away due to multiple heating cycles.

No heat in the cab. Temp guage doesn't move. Have lost antifreee, but no visable leaks.


Had the same problem with my 97 dakota (3.9). I reversed flushed the heater core and the problem is solved... too much heat. Instead of flushing the heater core normally, reverse the intake and exit lines and flush. Whatever is lodged in the core's intake should be discharged.

No heat 1999 Jeep Cherokee


...You need to make sure you have the correct thermostat! Usually, there are 160, 180, and 195 degree therms for this jeep. 195 degree therm should be used no matter what the season. If you have a lower temp therm., you will not get good heat (or any at all) in cold weather. Also, You should flush and fill your cooling system to get any contaminants and/or debris out. Check the heater core...it may be **** at this point!
