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.

98 ford ranger no heat have changed thermostat water pump heater control valve


Maybe the heater core is plugged or you haven't bled it properly?
If the heater hose returning from the core to the water pump is NOT hot, while the hose going to the heater core from the thermostat area IS hot, then the heater core is plugged probably.
You need to remove the heater hose while cool,from the thermostat area and remove the hose from the water pump area (that's the outlet of the flow thru heater core) AND THEN take a garden hose with p-is-tol grip type sprayer,and blow water back thru the outlet hose out the inlet hose. This will blow any bad plugging material out the way it got in.
Don't apply too much pressure if it is plugged bad. The heater core isn't made to stand 50lbs. water pressure. don-ohio (:^)

2002 nissan altima heater problem


have 2002 altima,blower works no heat at idle and very little heat when accelerating.I changed carbon cabin filter,made sure little gear under dash to temp knob wasnt broken,flushed and bled system.Nothing worked so checked hoses to heater core and found inlet hose was hot,outlet hose was not.So investigated this problem and came to conclusion heater core was clogged.An easy way to check is to get car to normal running temp. put on heater and blowers at full.Go under dash on passenger side where counsel meets firewall,this is where heater core core inlet and outlet aluminum tubbing go through firewall,you will be able to feel both tubes one closest to you is outlet, so if this one is not hot and and other is your heater core is clogged.I detached both inlet and outlet hoses to heater core from water control valve.Then I blasted water with waterhose and nozzle set at jet,first through outlet hose to blow gunk out,then through inlet hose until water runs clear.Reatach hoses fill and bled system.heater works great nice and hot!

I have a 1996 Dodge Ram 1500 with very little heat. The lines get hot going to the heater core, but I do not get enough heat out to keep the cab warm. I contacted heatertreater, but my hot cold control...


I have the same truck, I have flushed the radiator both ways, flushed the heater core both ways flushed the engine four times, I have owned this truck for eight years and still cannot get it to heat up the cab. It will keep the windshield defrosted but that is all. If you find any tricks to fix this let me know PLEASE

My heater wont blow hot air.. Just barely warm. I replaced the thermostat but the temp of the heater air has not changed.... Any ideas?


feel the 2 hoses going to the heater core (inlet & outlet) when the engine is warmed up.if there is a noticeable difference in the temp,your heater core is plugged up and will need to be replaced or possibly flushed out. Also check the temp cable to see if it goes all the way to hot

Replaced thermostat in my son's 1991 Jetta 1.8L, but still cold air coming out of heater.


Check the lines coming into the heater core. With the engine running, touch both lines, they should both be hot. If not, you have a blockage in the system. If they're both hot, you may need to replace the heater core.

No heat in cab in ford ranger 2005 tied heater


check if both heater hoses going into firewall are hot.. if only one is hot then your heater core is stopped up..you can take both lines loose and take a water hose and back flush,,, force hose on one inlet of heater core for a minute and then the other.. keep going to you get a good flow...make sure heater valve is open, not just valve position take loose and confirm clear..last make sure your thermostat is not stuck open keeping engine from comming up to temperature

Heater won't heat in cab


if the inlet and outlet hoses are getting hot to the heater core then the problem is the air temperture control blend door actuator in the heating/A/C ducts, this door directs air flow either across the heater core or the AC evaporator or mixes the 2 air flows for a desired temp at the outlets, hence the name blend door, to change this part u must remove the dash assembly.
