SOURCE: new heater core and thermostate /no heat

sound like you have a bubble in the system. make sure you drain all liquid out, make sure the thermostat is the proper temp rating and is not backwards. Fill the radiator up turn the car on turn the heater on full blast fill up the over flow with anti freeze. put the radiator cap on. watch the temp in the car. dont let it get all the way in the red. you should see the overflow tank start to get the anti freeze sucked out of it don't let run dry. I had this problem with my 2004 dodge ram. This is how a master mech told me to do it

SOURCE: no heat

Either your heater core is plugged or the system has an air lock. To cure an air lock loosen the rad cap, not the overflow, to the first notch and run the truck for a day or two. Check the coolant level often and keep it topped up. If this doesn't solve the problem you could try a "reverse flush" on the system to loosen up whatever is blocking the heater core, otherwise you'll have to replace the core. Hope this helps.

SOURCE: no heat. Had it in to a mechanic, replaced heat

Did he check the a/c heater housing flaps and solenoid/motor links that opens and closes these FLAPS for a/c and heater? Sometimes the solenoid activates and LiNKAGE seems stuck to open the heater FLAPS/DOOR. Bring it back to the mechanic and test those links and motors that i said! Hope that helps u out! taah!

SOURCE: 02 maxima blows no heat. Only one hose going to

If only one hose going to the core is hot, then the heater core valve is bad. It's what stops or allows hot coolant into the core. Only one hose being hot means coolant is not traveling through the heater core. Have that valve checked out.

May have a clogged heater core, feel hoses going in and out of heater if they're warm, suspect blend door actuator under the dash they like to break! Sometimes they make a faint noise when switching from hot to cold. If hoses are not hot check the hoses for a valve usually vacuum controlled. Have a helper play with the heater controls if the vacuum doesn't exist to the valve it won't open. If you have vac at hose valve is bad. Rate my answer and let me know how you make out

Dakota v6 has new heater core, thermostate, can hear blend door opening, and upper hose and both core hoses are hot but still no heat. dummy temp gauge looks like it might be reaching 160 range instead of...

160 degrees should be hot enough to get some heat.
You could check the engine temp with a scanner to confirm.
I would double check the blend doors, and the temp of the coolant in and out of the heater core. I use an inferred temp gun.

I have a 2001 s10 and no heat and I clean out the heater core and the water is not getting hot it's running bout 125 what can I do to fix it.

These s10 s have problems with the heater core plugging up, you said you cleaned the core, you used a water hose to flush the core at the core and flushed going both ways a few times, the cooling system even with a bad thermostant will put out heat it would just take a while so your saying theres no heat at all so that eliminates the thermostat, make sure the system is bleed of all air and try runniong the eng with heater hose to core removed and see if coolant flows out of the hose. this is to make sure the pipe is clear to allow coolant flow. also check and see if both hoses at core are hot, if one is hot and the other cool then the core may be plugged.if both hoses are at the same temp then you may have a blend door problem. i have seen the vacuum line that controls some of these that still use vacuum to control blend door instead of actuator have a broken vacuum hose at the engine at intake area. if the vacuum hose is off or broken then cool air is all you will get. check around the intake, theres a vacuum line that runs to the firewall on the pass/side and goes inside, make sure that line is connected and has vacuum. good day

No heat in 1995 crown victoria, thermostate has been changed. the rad was flushed, Hoses top is warm to hot, lower is warm to cold , car is not overheating

feel the hoses that go into the heater core at the firewall,if both are hot,either a door under the dash is stuck shut or you need to flush your heater core by removing both hoses and flush with water hose

Heat dont work might be bad hoses or put on wrong need diagram on how it goes 1993 Chevy K1500 getting sick of the cold

The hoses are two different sizes.One will be 3/4 and the other 5/8.No way to mix them up.May be your blend door not opening alowing air to flow across your heater core.I am not sure if there is a mixing/control valve.Feel both heater hoses as well as your top radiater hose just to make sure that the thermostate is not bad.You can look on and search "heater"to get a look at the door motor.You can remove it and open it by hand to see if you get heat.Well hope this helped.

2000 GMC Heater Problem

I had problems with a similar truck,a 1998 GMC diesel after checking to make sure the control cables were operating the blend door and blowing the mess of the heater core,I replace the thermostats.Still no heat turns out there was a small amount of debris collecting in the fitting for the inlet hose at the thermostat housing after removing it and blowing out the lines the heat was fine.
