Year, make and model? Some Fords have a bypass in the heater hose assembly. This does push coolant threw fast enough, causing the heater core to accumulate sediments, clogging it up. I use a 4 to 1 mixture of muratic acid(1) and water(4) to clean them out. Remove the hose from the engine(clamp off the bypass hose). Blow out the coolant. Use a funnel to add acid mix until it comes out the other end. Let set for about 5 minutes. blow it out( this is the bad part, because it sprays around. And it will get on you and it does burn somewhat). I do this at least two times blowing each direction in the hoses. This usually takes care of the problem on 90% of the cars I do. The other 10% replace the heater core. Big job there.

How do I get the front heater to produce warm, hot heat from the blower? for 2003 kia sedona


If the heater hoses for the front heater are getting hot, it could be a blend door problem under the dash.

First I would check your radiator fluid level, sometimes being low can have this effect. Usually the rear heaters sit at a lower level and so keep working. If that is fine, then you probably have an issue with the diversion door or controller that controls the hot/cold mixture.

Make sure the heater hose is hot with the engine is warm. The heater hose goes into the firewall and into a heat exchanger/ blower fan that will give you defrost and car heat. If the heater hose doesn't get hot you may have a blockage in the hose or at the radiator outlet.

No in car heating,blowers working fine but it wont produce heat. Its a 51 plate grand cherokee Thanks


If it won't produce heat then you have an issue with your heater core. The heater core could be bypassed, in which case no hot coolant will get to it to produce heat inside the cabin. The heater core could be stopped up with dirt/debris, in which case the heater core can't radiate heat to produce heat in the cabin. The ducting in the dash could not be allowing the hot air to flow to the vents - therefore no heat in the cabin. I'd start with the heater core and check to see if it is bypassed. This generally happens on older vehicles because the parts can be harder to find.

2000 Silhouette: HEATER WONT GIVE OFF HEAT THEIR IS HEAT BUT WONT S...


Check the water level. If the water is low it will not allow water into the heater core to produce heat. If there is water keep an eye on your temperature gauge It should reach at least 140 to 170 degrees. If it is staying colder than that you have a stuck thermostat which is allowing the water to flow to much and not let the engine warm up. The only other solution is if the fan is not working properly replace the fan relay for you blower.

2003 dodge durango front heater will not blow heat. but when driving heat will slowly come throught the heater vents. what should i check?


Since your blower is working and it is a heat issue,thats where we'll start,First thing is have you checked the coolant level in the radiator when engine is cold,make sure it is filled to top,next verify you have coolant in reserve ,Start your van and get it up to normal operation temperature,If your heat gauge on the dash works correctly it should be 190 degrees,Now lift the hood and locate the two heater hoses going into the heater assembly at the fire wall,Both hoses should be hot to hold on to,if both are hot and no heat inside your problem will be the blend air door in heater assembly.
if neither hose is that hot you need to replace the thermostat in the engine to get it up to 195 degrees.
if one hose is hot and one is luke warm then the heater core is blocked and to blame. hope this helps you.

2006 ford f-250 diesel with no heat


it takes quite a while for a diesel to warm up by just idling in order to produce any heat.you have to put them under a load (drive it), before you will get any noticeable heat.if you have a block heater, plug it in 4-5 hours before you plan on driving it and that will definitely help produce interior heat quicker.
