View 13 RepliesFord F-150 - 1997-2003 :: 1999 - Replacing The Heater Core
Friend of mine has a 99 Ford F150 with the 5.4L. He thinks the heater core has gone on it as it blows a mist through the top vents when he turns the heater on. He can also smell antifreeze. Up here in Canada, its, well quite cold, nuff said about that. He has had estimates of anywhre from $800-$1000 to change it whereas the cost of the core is below $100. Is there anywhere that he can get a diagram.... of how to change it, all he knows was that he was told to remove the entire dash to gat at it.. Is that true ?

I have 1998 F-150 and the heater core was replaced 18 months ago. All was going well until about 2 weeks ago I noticed under heavy acceleration I would smell antifreeze. The smell would clear up and would not re appear for a day or so. Finally the other day when it was 8 outside I got in the truck and got about 5 miles from the house started up a hill and it was like a fog machine was mounted behind my dash the windows fogged up almost immediately so I figured great the core went bad again. Now the temperature has warmed up the last couple of days and there is nothing no fog in the cab the heater works fine just an occasional slight smell of antifreeze. Before I go through the trouble of tearing out the dash is there anything I should check I already checked the connections on the firewall and they were fine.
View 5 RepliesFord F-150 - 1997-2003 :: Heater Core Replaced - Air In Cooling Lines
I have a '03 f 150 screw 4x4 with 5.4. I had to replace the heater core in the truck and I could hear air going through before the replacement. Now I can still hear it, have tried to burp the system a few times, even jacked up drivers side front on an incline to get reservoir higher. Ended up replacing the hose with the flow restrictor and that worked or so it seemed. The noise is back and I am lost on what to do next. I tested the head gasket and that came back negative also. What to do next or possibly what the issue is?

My heater core must have sprung a leak this week. Not that I need heat in this weather but just the smell of it while running the A/C just stinks. I know I am going to have to replace it myself but just for S&G, what would a dealer charge to replace it?

Have a '02 f150 and thinking the heater core slowly dieing. Have noticed for several weeks a nice line of water leaking onto the passenger side floor. Do you have to take off the entire dash to get to it? Will be doing replacement myself as the dealer or shop would probably kill me on labor.

New, to me, 2002 F-150 that developed heater core leak. I tore down the dash and replaced the heater core and reassembled everything.
All is good except that now the air bag light on the instrument cluster stays on continuously. There is no blinking...just a solid light that stays on.
I must have missed a connection, though I'm at a loss because I thought I got everything. Is there an obvious (though not obvious to me) connector that I should be looking for?
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.
Ford F-150 - 1997-2003 :: A/C Blowing Warm Air At 1500 - 2000 RPMs - Heater Core?
We got our first taste of fall weather in Houston this weekend, and with it I've discovered a new problem with my truck. After the engine was up to temp, I noticed that the heater would blow cold air any time I sat at idle. If you rev up the rpm's to 1500-2000, you can feel the air start to get warm again. I'm guessing this means my heater core needs to be backflushed.
