    Aftermarket Coil replacement

    I have a 5.4L 2003 Expy and a 6.8L 2002 Exped that use the same coils. The only coils I have had to change was one that cracked at the base of the connector and another that had a broken tab after the spark plug blew out. The boots and springs have been problems. You can get a NAPA...

    Ignition Coil and Plg Replacement....What Brand to Get?

    It seems like a lot of people just change the COP (coil/boot/spring) to fix a misfire without really trying to determine which part of the three is bad. Our 2002 6.8L has 108k and 2003 5.4L has 154k with original coils. Except for one that broke the mounting tab when the plug blew out and...

    Ignition Coil and Plg Replacement....What Brand to Get?

    Why are you assuming the coils are bad? Get a couple of boots/springs and try those first. The NAPA 702418 boot/spring is fine. I change the boots with the plugs at 50k. If it's rainy or humid when it's misfiring look for a cracked coil housing or a water leak onto the engine. I've had...

    Cooling lines not flowing

    I'm not going to change out a perfectly good working original radiator just to replace the trans cooler in the lower tank. I've never liked the idea of having the trans cooler in a radiator tank because I know a couple of people who have had their trans ruined by a cracked radiator cooler. So...

    Cooling lines not flowing

    After many tests and gallons of fluid I think I have a handle on the problem. I don't think the hose kinking was any problem. It wasn't that way for long. I do have a flow problem. The fluid did look a bit darker than usual, not enough was coming out at first to really tell. I isolated the...

    Need Help Please Before I Lose My Mind

    Do you need to disconnect the trans cooler lines from the radiator? Can't you disconnect the tubes on the side of the trans?

    Cooling lines not flowing

    There are 2 places I can hook up a drain hose. I must have used the connection before the coolers in the past. I have new hose fittings/drain lines and for the original post I connected after the coolers. When I connect before the coolers there is normal fluid flow - a bit faster than I can...

    Cooling lines not flowing

    Just crawled under the car and I don't see anything that might be a cooler bypass. The 2 cooler tubes come out of the right side of the trans, one right above the other, and go straight up to the radiator/aux coolers (towing package). There's no cooler bypass tube or any type of bypass block...

    Cooling lines not flowing

    Oops, new to this forum, thought the info would show on my ID. I have a 2003 Expedition XLT 5.4L with the 4R70W trans.

    Cooling lines not flowing

    I was changing transmission fluid, like I have done several times before. Trans has been working fine, just time for a fluid change. I pulled a cooler hose and added a drain hose. I was pumping fluid into a container while replacing fluid via the filler tube. The hose got kinked and the...
