December 1, 2005I've got a low-temp T-stat in the truck, could this be the problem? In the day time, the heater is semi warm but at night when the temp is 30 degrees or so, you may as well forget about any heat at all, should i change the T stat, or is there something else i should look into?
December 1, 2005YOU SHOULD LOOK INTO SEE IF THE HEATER CORE IS BAD OR NOT. I HAD ABOUT THE SAME PROBLEM WITH MINE.
December 1, 2005you can try flushing out the heater core, in some cases it will restore the heat
December 2, 2005i was thinking the heater core may be clogged, how do i go about flushing it out?
December 2, 2005Here I found this on another site, it's worth a shot!!!
Well, I just had the Evap Core replaced yesterday, and maybe the heater core, but the radiator shop said that the heater core still looked really good. Anyways, I haven't gotten to use the heater until this morning due to it's just now cold enough, and it wouldn't get warm hardly at all. It would get like barely luke warm . My truck is getting about 180 degrees, but no warm air really at all. I let it warm up for about 10 min., then drove to my parents house this morning, left there and drove to work, and still nothing.
Any suggestions on what to do? Radiator guy said that maybe there's an air lock, but if that was the case, wouldn't my temp guage get too hot, or not hot enought too? Anyways, any ideas would be greatly appreciated.
**Fixed** Well, last night I took the female adapter off my washing machine and hooked it to the end of my garden hose. I then unhooked the heater hose outlet (driver side) from the water pump, and also unhooked the inlet side (passenger side) where it splices about half way down the hose from the firewall. Next, turned the hose on, and held it up against the outlet hose and blasted all the gunk out of my heater core. Let it run thru for a few minutes until there was only clear water. Then hooked it all back up, all of this maybe took 15 minutes. This morning, started the truck, 5 min. later, HOT air!!!!!! This kicks ***, haha. The little things in life I guess...
December 2, 2005that sounds like it may work, just wish the description of how and what he did was a little better..
December 5, 2005you might make sure that there is anti-freeze in the engine. I had the same problem with an old car I had. If there isn't heat from the heaters, I found out you should check the anti-freeze first. you might be able to save a lot of money if that is your problem.
January 22, 2006When I had my heater core flushed. my mechanic said that most of the daks he's worked on have the same problem. But try flushing the system out & keep coolant full & see if it helps.
January 22, 2006My truck gets to be like an oven after a while, but i'm thinking of getting a 180 thermostat myself.
January 22, 2006I just went and flushed my radiator the way listed above and I can't even begin to describe the difference..... I went from not being able to defrost my windows, to now having the windows rolled down and still feeling the heat coming from the heater. I took it to the local car wash to do it since i didn't have access to an unfrozen hose. It took all of 10 minutes and $2.50 for the self-serve bay I used. Best repair I have done yet. Only wish the body work I need on my Dak was gonna be that cheap for me, lol. Blu98Dakota..... if you need pics let me know, I will take some and email you the way to do it if you haven't done it already. It is really simple as can be.
January 24, 2006Please post the pics and describe a bit better. I NEED to do this soon.
