99 Taurus heater not working.

Recently flushed cooling system and changed thermostat. Engine comes up to temperature. I have run water through heater core to check for blockage. Heater door actuator is working properly. There is a little heat coming out when the heat is switched to the floor and the blower is on low. Any other changes will make it blow cold air. Any other ideas?

With the car idling put on glove and squeeze the upper radiator hose in your hand you should feel the surge of coolant if the water pump is working properly so if you do not feel this then it could be your water pump and also check to see when was last time the drive belt was changed

Sounds like you may have an air bubble trapped. Try loosening the radiator cap & running the engine at 1500 rpms till the thermstat opens & see if you can "burp" the air out. You may lose a little coolant this way. shut off car & recheck coolant in radiator and reservoir bottle. Just because reservoir is full, doesn't mean radiator is full.

What should the temperature of the heater core inlet hose be?


heater hoses run from the rear of the block to the water pump. One hose into the heater should be hotter than the other because heat is transferred in the heater in the car. . The cooling system draws water from the bottom of the radiator ( water pump inlet)which is always cooler than the top hose and dispenses it throughout the engine and heads including the heater core. It is then pushed past the thermostat with all the heat from the engine to the top of the radiator where it is cooled down by the air passing through the radiator . Check that the air vent for the cabin is set to recirculated cabin air and not fresh air from the outside as it will require recirculated air to increase in temperature to work properly

Truck doesn't heat while idling


Could be low on antifreeze. The heater core is the highest spot in the cooling system and it may develop an air pocket. Another possibility is the thermostat is stuck partially open and doesn't let the engine warm correctly, watch your temp gauge on the dash and see if it comes up to the middle like it should while idling. If it doesn't, it may need replacement.

No heat , replaced radiator , water pump, rad. cap , hoses and flushed system twice.blows cool air.whats left?


Thermostat.? if you haven't? Do it first then try it. While the car is running for a while touch the heater hoses that lead to the firewall. if one is cold and one is hot? You have a blocked Heater core. Follow the hoses back to the engine. Unconnect them both. By using a garden hose flush out the heater core do one side and then reverse by doing the other hose Lots of junk will come out so be care ful. Mistake people make is "Flushing the system" That doesn't mean your flushing the heater core.
Seeing that you have done everything else it could be the thermostat which you didn't list or the heater core being clogged. When you finished installing the thermostat and flushing the heater core out. Replenish the coolant system . If you have a bleeder on the thermostat housing? use it . loosen it and top off the fluid until you see fluid comeout of the bleeder. The system being air bound would cause no heat..

Heater doesn't work. Thermostat or heater core?


We can rule out a lot of things. Its not the thermostat, as if it was stuck open, it for sure wouldnt get any heat on the freeway, as cold air would be cooling down your radiator and making the no-heat issue even worse.

Second, it can't be a problem with the "dash" components, as they are all electrically operated, and it would make no difference whether the car is moving or sitting still. Either you have blockage in your heater core or you have an air pocket in the heater core. Beyond that, theres not much else it can be, if the water pump was broken, the car would over heat for sure real quickly.

If it's equipped with the 3.0L OHV Vulcan V6, NOT the 3.0L DOHC Duratec 24 valve V6, those engines are norotious for having the "brown" coolant problem. Casting material was left inside the engine blocks of those particular engines when they were manufactured new. Consequently, the cooling systems in those cars with that particular engine would be contaminated with rust. The unique way to fix this problem would be to perform several thorough flushes of the entire cooling system, which includes back flushing the heater core, the radiator, and specially the engine block.

It wouldn't hurt to replace the thermostat as well, while you're "in there". ot, you could have a control issue. To check this. Turn your climate control fan on to medium speed, and cycle the temperature control from FULL COLD, to FULL HOT. See if you hear a change in air flow. If so, the problem is in the cooling system. If not, the temperature blend door actuator has failed, causing the air not to circulate through the heater core. The only way to repair this, would require instrument panel removal for access the failed components.

I hope this helps (remember to rate and comment this answer). Keep in touch.

04 Chev. Avalanche 1500 Z71 5.3 125K mi. Temp gauge reads erratic from 210 to 245 or so. heat blows warm then cold. Coolant level, OK. I have been told could be sticky thermostat but usually is restricted...


Normally the engine operates at 195F, if you did not replaced thermostat with another one at 185F. If the temperature has a tendency to rise up, the reason is a partially obstructed cooling system or/and a bad thermostat.
The first part of the cooling system that gives up is the heater core, because the coolant flowing channels are thin. You got a good advice but not the best one. It is the time for a coolant flush in your car. To do do it right then you need time. Plan ahead for a week end. With a cooled engine, start as your friend advised you with the heater core hoses. Disconnect both of them, but the dirt has to go out of your car, so with a garden hose back flush it and let the dirt to get out of your cooling system. After you will get clean discharge, it is the time for coolant bottle, remove it, discharge the used coolant and clean it. The third to come is the radiator. Open the drain cook, or disconnect the lower radiator hose, and disposal used coolant properly. Now open the radiator cap and flush with water the radiator till discharge will be clear. You think that you are done? Not yet. There is half of old dirty coolant trapped in the system.
Install everything, and connect all coolant system hoses, radiator, heater core and coolant bottle. Now you have to run your car with water. Fill out the cooling system with distilled water, start engine, turn on the heater high, and run till upper radiator hose get hot. That means the thermostat opens.
Let the engine to cool down, open the radiator cap, and draining cook or lover radiator hose and drain everything. You can use flush detergent if you wanted at this stage, but flushing with detergent will add 4 more hours, because detergent is colorless and you have to guess how many fill and drain processes do do to get rid of it. I do not do it, but if your cooling system is very dirty you have to do it. After the last drain, fill the cooling system with concentrated antifreeze and 30% distilled water. The reason is because it is more water trapped inside the cooling system. The goal is to reach 50/50 concentration. You need a coolant tester to find this. Start the engine and add coolant til radiator is full. Install the radiator cap and bleed the system. After driving you car for a day or so, let engine to cool down, open the radiator cap check the concentration of coolant with the tester and add antifreeze or distilled water as necessary. It is a good idea to replace the thermostat while flushing the radiator. This procedure has to be done every 2 to 3 years. It is up to you to decide to use RED GM Dex-Cool or GREEN Prestone antifreeze.
In all my cars I have replaced Dex-Cool with Prestone, but I flush the system every 2 years, and I never had a cooling system problem in all my cars.

2000 Leganza no heat; heater core is not leaking; blower works


try and see if there is any bleed screws on the water system ie near thermostat housing or top hose sounds like you have an air lock in the water system if the blower is not getting warm

Changed the thermostate and drained the radiatior and put new fluids in brought car to running temp but heater still wont blow hot are


Feel of the heater hoses going to the heater core,if they are not getting hot,then remove the heater hoses and flush the heater core out with a water hose.Also be sure to bleed all the air out of the cooling system.

The heat system is broken


Hi,

You haven't said what is actually wrong with the heat system (there can be several different failures). For the time being I'll assume the fan blows plenty of air but the air is always cool/cold regardless of where the heat temperature selector is positioned.

The most common cause on these cars is a plugged heater core. With the engine at normal operating temperature, feel the heater core hoses (under-hood, mid/lower portion of firewall, access from passengers side). They should both be very warm. If not expect blockage in the heater core.

While a replacement heater core along with a good cooling system flush is the ultimate cure, reverse flushing the heater core will restore heat. This can be accomplished with a garden hose. Disconnect both heater core hoses (not with the engine hot as the coolant get very hot!!) and connect a garden hose. Turn on the water supply to flush the core. Flush the core in both directions (by hooking the hose to one side of the heater core and letting the water run, then disconnecting and connecting to other side of the heater core...). An old garden hose with end cut will work fine if your existing hose will not fit over the pipe (plumb it together anyway you can).

The heater core sits rather low in the cooling system. This means crud in the system will settle there eventually causing blockage. If you flush the core the crud will eventually cause blockage again. Reflushing will work over and over again if saving money is the primary goal.

If this is not the problem, the blend air door is probably not working.

Reply and we'll continue. I don't want to repeat things that have already been done, as $2000 should of covered both things I have mentioned.

HEATER DOES NOT STAY HOT IT STARTS THEN IT GOES COLD


Check the heater core for a clog or the heater control valve. The easiest was to check these is allow heater to run for a few minutes and check the two hoses coming from under the hood against the fire wall. They should both be hot. If they are not, you have one of the above problems. Start with the heater control valve and replace it. It is much cheaper than than a heater core. Next, you will need to pull the lines from the firewall and see is rust starts coming out of the lines, if so, you may be able to flush the system and clear the blockage. After that, if it does not work, it will require replacing the heater core, which is no easy or cheap feat.

Let me know if there is anything more I can help you with.
