    Proper coolant 7.3 IDI

    Searching keywords like "coolant" and "fleet" or "charge" seemed to turn up page after page of irrelevant threads. The information may be here, but it is buried among other topics. i suppose I will keep digging.

    Proper coolant 7.3 IDI

    I replaced the thermostat and radiator on my recently acquired '91 7.3 Turbo. I have flushed with distilled water several times and need to fill it back up with the proper coolant. The previous owner gave me a half empty bottle of Peak "fleet charge" that is pre-charged with SCA from when he...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I'm quite certain it has never locked up. I know what it should sound like when locked and I've Definately never heard it. While the fan work g properly will probably keep me under 250*, I'm still a little apprehensive that it will keep me as cool as others are claiming to be. If the fan really...

    Pre-turbo. It's in the pipe that bolts to the drivers side manifold.

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    In my truck between the o-r in normal is about 210*. Perfectly safe I didn't realize the fan clutch would partially engage, I guess I was thinking it was all or nothing. I've read that some of the aftermarket clutches can be bad out of the box. A motorcraft yb467 should be pretty reliable...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I found a motor craft fan clutch for $90 so I am about to order one. I just can't see how a fan clutch would help keep me as cool as some guys are saying. I can hit 220 unloaded if I maintain speed up a hill. I can't drive easy enough to keep it under 205* around town. If the fan clutch will...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    Good point. What I drained out was precharged with SCA, but I wanted to switch to gold ELC. I figured I would need to completely flush the old stuff out because the ELC is not compatible with traditional stuff. I thought it would be a good idea to run water for a couple days, but didn't even...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    Since its going to be close quarters, I may just pull the radiator anyway. I only filled it back up with distilled water for now, so I wont be losing any good coolant. And its fairly easy. With my luck I'd poke a hole through the middle of it wrestling with the fan.

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I have no idea about the timing. However, doesn't that cause exhaust temp to run too hot before anything else? I've never seen EGT over 1000 on this truck, and very rarely over 850. From my Powerstroke background where anything under 1350* was safe, this truck runs very, very cool on the EGT...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    Just got back home. Took a different route home from the park to avoid the interstate, but that wasn't a very good idea. Immediatey after leaving the park, there was abot a 4 mile stretch of road that really had the truck working hard. I was going slow (30-35mph) to try and keep temps under...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    It doesn't have much of a fan shroud but it looks OEM. This does remind me,though, that the fan shroud doesn't sit quite right on the champion rad. I could seal up the gap with some foam tape or something but I doubt that would keep me 20* cooler. Side not.... EGT stayed around 700-800 most...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    Unfortunately, the truck ran quite warm today. It's a shame, I can tell there is more power to be had but I had to stay out of the throttle to keep water temp down. Made most of the trip around 55-60mph with water temp between 220-230. If I tried to maintain 65 even on relatively flat terrain, I...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I'm not worried at 210*. What worries me is that if it runs 210* empty, it will run too hot when I'm working it. I'll find out in a few hours...

    Manual High Idle/Advance

    In case anyone searches this in the future Ill add an update: My factory harness had been cut at the junction where the high idle solenoid wires into the factory harness. I didn't realize this until I cut into the loom to reveal what was underneath. The two wires appearing to go to the high...

    Cold Timing Advance not working

    Guess I should update this in case anyone comes across this thread while searching in the future. I found out what was going on. I had to dig into the factory loom a little bit but not too far into it. The previous owner had rigged up a manual high idle switch, and completely cut both wires...

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    Headed to the lake for the weekend tomorrow. Will be the first real time I have it hooked to a load for more than a few miles. Staying local-ish....will report back with how it goes!

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I've never seen exhaust temp over about 850 and the pancake down pipe has been replaced with what looks to be the biggest you could possible squeeze in there....I'm guessing 3". I have no idea where the timing is at.

    Running Warm Under Load; Using OEM gauge location vs Overtemp sender for gauge?

    I bought a 91 7.3 with a "factory" ATS turbo a few weeks ago. I bought it to pull our 9k pound travel trailer (near the truck's comfort level, I know) and haven't really had a chance to put it to work much yet. I bought the truck thinking it was a complete, mechanically sound project but soon...

    Cold Timing Advance not working

    I've been in here a few weeks and have already learned more than I really ever intended...I didn't even know there was a timing advance either. It was only once I started poking around with a test light that I learned there is supposed to be one, but mine wasn't working. I'm still surprised...

    Cold Timing Advance not working

    I temporarily repurposed a switch I have in the cab to run the timing advance. It sounds slightly different when it advances so I guess it works. I expected a more dramatic change in sound based on what I've read. But it does something....guess I need to cut open that factory harness and find...

    Cold Timing Advance not working

    Right. Truck sat overnight and engine is cold. With the ignition on, both terminals at the switch should be hot (which they are) and the connector at the advance on the IP should also be hot (but its not). I think we're saying the same thing, or do I have it backwards? Also, when you say...

    Cold Timing Advance not working

    I haven't noticed any adverse symptoms from this, but I've determined my IP timing advance is not working. I didn't even know the truck was supposed to have an advance until I started digging around these forums....dangerous place!!! I replaced the thermostat in the truck yesterday and...

    Manual High Idle/Advance

    awesome, thanks. One last question.Ive read through the attached article a dozen times and it still isn't cear to me....The OEM setup has two wires coming from the temp sender harness going to the high idle solenoid. Why is there two wires? Are they both hot? Assuming I was starting out with...

    Manual High Idle/Advance

    So the article above with diagram will accomplish what I want it sounds like. What purpose does s relay serve? Not sure why some other threads I read were so insistent on a relay? I'm trying to find a radio shack locally and that's proving to be difficult since it's not 1997 anymore....if I...

    Manual High Idle/Advance

    I've done some more searching have read about hookimg up the high idle using a diode and a relay. I'm not sure what the relay would do....maybe I'm Misunderstanding what can be done. Is there a way to allow the cold advance and high idle to work automatically as intended *and* have the high idle...
