Ford 7.3L Power Stroke (1999-2003) :: Replaced Injector Cups - Too Much Heat From Heater Core?
Aug 5, 2015
I just finished the replacement of my injector cups and I replaced every hose on that engine and when i replaced the heater hoses I believe I hooked them up right but just want to make sure. Is there an IN and and OUT on the heater core or does it not matter???? Im only asking simply because my legs feel like their on fire. 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.

replaced heater core because when pulling a trailer it would admit steam out the defrost vents and the smell of antifreeze, what it could be?

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".

Have the Alliant 6.0 specific bore brush kit on the way, however was curious how others use the brushes? My concern in whilst cleaning the bores, debris might somehow work it's way up into the fuel passages with the up and down action, risking said debris lodging in those tiny screens of any adjacent injectors which is the last line of defense against debris. Am I missing something? Correct me if I am wrong but with the injectors out those passages are just open to the world, correct?

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?

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?

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 dealership is having problems with heater core repair. 2002 Ford F150 Supercrew. Problem is antifreeze (or early on just smell) in the cabin. 4 heater core replacements in 2 years. A hose (?) replaced. Electrolysis kit replaced. 4th heater core replacment finished yesterday. I know that I need to let the dripped antifreeze work out of the system, but I am smelling mild antifreeze this AM. Usually gets worse over 2-3 days then I have to take it in. What might be being missed here?

I replaced the heater core in my truck. Now it will not turn over. When the key is turned on all the lights in dash come on like normal but when I turn the key to start it I get nothing.

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 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.

I was driving and my truck started have lack of power, could barely get going on hills, tons of blue smoke (smelled like diesel) real rough idle. I unplugged injectors and found #5 made no difference. I replaced it today and I can't get it to start. It'll get to 2000+ psi 48v ficm, low pressure oil registers, ficm says its in sync. It will crank and blow a lot of black like its half firing or something. It has even crank to, until it tries to fire. From what I've been reading could it be the ficm? That one circuit is fried?

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 in the process of replacing the injector cups and i knew this would happen since the whole process went way to easy up until this part. I am using Clays remover kit and it will not remove the cup. I do it according to the book and it just keeps popping out of the cup when i try to remove

Now ive got a tick tick tick tick sound from the engine. The tick increases and decreases with rpm and is present at idle. If it were a gasser i would say a lifter, honestly it kinda reminds me of a sewing machine lol.
Whatever it is as long as its not serious and my engine is solid im ok w it, I bought this truck knowing I was going to have to put work into it, I just didn't know work was going to go fall one after the other week by week from the day I got it....the previous owner must really have neglected this thing....
Hard to hear it over the sound of the engine, but its there, and is slowly getting worse

Although not certain, I *thought* I saw coolant run into the front drivers side injector hole when the injector was out and I leaned on the radiator hose. I had knowledge t pull them and changing the orings who were initially concerned then not concerned after looking closer.
Either I made a mistake in what I thought I saw on my first experience with injectors, or there really is a problem that I didn't know enough about to address at the time. So I opened this thread to get more info and stop hijacking 67speeda's thread, found here: [URL] ....
As per recommendations, I will check my coolant bottle for any fuel, oil, residue, etc. I am also going to reach out to my buddies and see if they saw a problem with coolant, too, or they realized it wasn't coolant and I didn't take note of it ...
It was a REALLY LONG day and my ability to concentrate had begun to slip quickly (health issues), so it's possible I missed something there. So IF I saw coolant going into that cylinder with the injector removed, how bad would that be? I thought it came from pretty high up and ran down where the injector sits..

So after hitting a pothole, it would seem like half the engine lost power, after some searching around, i found that i would most likely be the harness inside the valve cover that has lost connection.
Its the right side, so i would need to take of the turbo pipe, and probably something else to get to it.
Since i'm doing this job, what to check out along the way? I want my 7.3 to be as reliable as possible.
I will probably ask some questions along the way, it can be a challenge sometimes to own a car that not many mechanics are familiar with, but as i have read online, this should be a very straight forward fix.
Can the harness be upgraded so it doesn't happen again? Its an 02

Story starts when I was cruising down the freeway and the truck cut out, seemed like a CPS or Injector related issue - seemed like a whole cylinder bank cut out. Stopped truck on shoulder, she shuttered and died. Turned truck off and restarted, ran like a top for about 4 miles then did the same again. I restarted it again and drive it straight home, ran like it I usually did.
As soon as I arrived home I did a little research and learned to start with CPS. I replaced my grey CPS with a new, Ford grey CPS. Truck fired up, ran the same that it did before - not the best idle but at 302k I was content. Drove it for a few days and it did it again, hobbled the truck home, although it did do it a few times and the last time it did it was really hard to start.
I replaced the IDM through NAPA. She's a work truck so I wasn't going to splurge for a Swamp Unit, the NAPA one came with an 18-Month Warrenty. She started right up afterward, the smoothest idle I had ever felt and she ran great, except for an SES. I ran the code and it was an IDM code, ran a buzz test and it pulled injector #5 high/low error, but it buzzed (a bit quieter than the others).
Here's the weirdest part, when the motor is cold the SES is constant, but as it warms up it only shows under power and sometimes flashes off at certain RPMs (1700-1900 and 2100-2300) and turns off when engine braking (TC locked) returns at idle. NO engine lights with the old IDM. I've checked the wiring to the injector from the 42-pin to the outer connector. (.6-.7 ohms, what my meter reads without any loads) Injector (from outer connector) reads 3.2 ohms. UVCH is less then 2 months old (GP issues) injectors have less than 5k on them.
Why? New injector solenoid? Bad IDM? Is it possible my last one never fired #5 and it got stuck? Or did my old IDM fry #5? Also I'm going to keep driving it and maybe it'll clear up, there was one drive I took where it cleared up completely. I've done some extensive research on this an i'm stumped. With the new IDM the truck has run better then it ever has.
