Heat not working in 2006 mdx acura

Had radiator flush after long period of not changing antifreeze following this the heat would only blow out lke warm air both rear and front. Since this time I have had radiator flushed and thermostat replaced without successful cure of the problem.About a week later started to ver heat brought back to dealer and was afraid I hab blown head get so preformed a pressure check which was ok not leak in gasket .He did find leak around thermostat and repaired . No more over heating but still no heat. I do hear water like sloshing sound coming from under dashboard since this problem started. Could it be the heater core and if so what is a reasonable price to do repair work. The car has 160k miles Frustrated and cold

The whole system is very simple. There is a valve that opens and closes on one of 2 hoses that come from the engine. If the heater core is not getting water, the valve itself is the problem. If they did the flushing properly they should have checked to see if that valve was fully open to allow the flushing process to clean out the heater core too. If there is sloshing in the heater core (check it by listening under the dashboard when heat is turned on) then there is AIR in the core stopping the antifreeze mix from going through its coils. Remove the heater switch on the heater hose and check it for proper action first. Next have a compressed air test of the heater core to see if it is clogged. If you fix this, try to do regular maintenance on your beautiful MDX!

It sounds like you are low on R134 freon, you might have a leak or maybe it just needs a recharge.

SOURCE: Oil leaking into coolant -- not head gasket

check the transmission condenser or oil cooler built in the radiator..

It sounds like low coolant to me if it is not leaking out anywhere it is possible that you have a head gasket problem. I would suggest pressure testing the system to see if you have a leak or if it holds pressure. if you do this yourself be sure not to exceed 15 psi.

Why isnt heat working?


yes that is very possible but if your truck did not overheat before this it is doubtful. make sure you did not put the thermostat in backwards. if you flushed out the system did you force any air through it to blow out old antifreeze? if you did, this may have broke some stuff loose in your heater core and plugged it up . it could also be air locked, if the system was completely empty and you refilled it . turn your radiator cap half open (not all the way open ) so it is still locked on but not tight and run your vehicle for a while to burp the air out of the system . add antifreeze if needed after this .

Heatdoesn't work, A/C blows out warm air and defrosts blow out cold air


Right think the problem is the heater core is blocked with corrosion ,now remove the bottom hose from the rad and the heater hoses then flush every which way you can including through the heater core reversing direction then ,refit all the hoses fill with water only and see if heater works if so the remove the bottom hose again and drain ,then add a minium of 3 litres of antifreeze ,its a anti corrosion agent as well as antifreeze and without it the internal of the engine will corrode and the slurry will block the heater first then the radiator ,

Why my 1993 acura legend blow's cold air but not hot air,the AC works fine.The cooland level is good too.What can ido to fix this? too cold to drive the car like this,please help...


It sounds as though your heater core is stopped up, have someone intelligent to drain your radiator and catch the antifreeze because of animals drinking it, it will kill the animal, then flush the radiator & heater core with a flush designed to cleanse the system, follow directions from flush manufacturer, then put the correct amount of antifreeze in your radiator. Wal-Mart or any parts place will have this in different brands. This may help, it did on my 1998 mercury Mystique.i hope this helps you
P.s. Just follow directions on the flush container & this can be done by the do-it yourselfer
Make sure you allow the engine to cool before pouring the new antifreeze into the radiator, could burst your engine block.

Why would my heater blow out cool air when sitting still and then hot air when going down the road and then it's not all that hot


Try flushing or blowing high pressure air through the heater core lines. its sludge build up and need to be flushed through heater core only. check antifreeze fluid level. only put in straight antifreeze, do not mix. most people do not know what mixture should be, so be safe and add straight, it will not hurt it, i run 100% straight antifreeze and never had a problem or worry about it ever freezing and cracking my block, heads or radiator cracking.
