Ford F-150 - 1997-2003 :: 2000 - Low Heat Output / Heater Core Clogging Up
I cant find my original post but I am reporting back on a low heat output issue. Not the climate door. It was the heater core clogging up. Instead of replacing, this is what I did. Purchased a "drill pump" and some clear hose and some CLR. Cut both the heater hoses,taking consideration of where best to install "T" connectors.
While hoses disconnected,filled heater core with CLR(as much as I could get in it). Hooked clear hose,drill pump configuration,on to the heater hoses. Ran drill pump in both directions for several minutes and stopping and letting it sit for a few minutes.
About 1 hour all together. Pieces of debris came out of the heater core and I could see it through the clear hose. Flushed the heater core out. Installed "T" connectors and it is heating very well now.
Gmc :: No Heat In Van - Blocked Heater Core?
I have a 2010 GMC 3500 Savanah van with 6.0 motor. No heat in van. Engine operating temp is normal. Heater hose into core is hot. Hose coming out is barely warm. I am of course hoping for another explanation other then blocked heater core. The truck only has 45k miles. I am ready to backflush , but wondering if there can be any other explanation. A/C works normal.
View 1 RepliesFord A/C :: Replaced Front Heater Core Now No Heat In Rear
2000 Expedition. Had ford mechanic replace front heater core due to not having heat in the front and back. wife brings it home I check all vents and notice there's good heat up front but not the back, then I switch the rear from panel to floor heat and hear a thumping sound (figure the blend door is doing it) still no heat in rear. returned to ford mechanic and they stated my blender door switch is not working properly, so they flushed out rear core and instead of fixing the blender door switch they kept it on floor position and charged me another bill. could it be possible that while replacing front core the gunk made it to the rear hoses and core, and clogged it up, and damaged the blender door switch somehow. prior to my heat issues I never had any problems with the rear blender door, just no heat due to front core needing replaced according to them "FORD".

View 2 RepliesFord - Explorer :: 2004 - No Heat / Not Getting Vacuum To Call For Coolant To Enter Heater Core
I bought a 04 explorer with a bad thermostat which led to a bad head gasket, fixed that and managed to not have to buy the special tools or time it , but now that its running I don't have any heat. I have complete service records on this vehicle and there was never a complaint of the heater not working. The a/c works and the heat will adjust the a/c temp, but no heat. In trouble shooting it I found that I am not getting vacuum to call for the coolant to enter the heater core. When I apply suction to it, it will send the coolant. Even though I wasn't getting the clicking noise, I pulled the blend door actuator and it looks surprisingly good (not looking forward to putting it back in). Where to look next?

Im wondering if the hot coolant is flowing through with out demanding it. I havent drove the truck in a while so Im questioning everything.

That is, coolant always circulate through the core, there is no "valve" that turns it on or off.
The HOT / COLD dial opens and closes a door (vacuum operated) that allow air to enter the heater core area?

Prius (2004-09) :: How To Check Heater Core Leak
I drained all the coolant from the radiator and engine. After I fill up and bleed the air from the system. I'm very sure no air inside the engine. The next day I found have air gurgling inside the heater core. Look like have a small leak but I check all the engine, host and radiator no leaks. The last think to think is heater core and heater core host. How can I check both parts? If they leak. How hard to change? Can I DIY?
