View 4 RepliesI have a 99 f150 XL 4.6, 5 speed. I spent some time tracing the leads around the ignition system to find the EDIS module. The purpose of this is to install a aftermarket tach coming off the EDIS. This seems to be a simple approach and I have a pin diagram handy for it. I am initially shying away from tapping into the EEC. Maybe better yet, what wire color to splice behind the gauge cluster that would be useful too.

View 1 RepliesOk I have a 97 f150 4.6L. My radiator has been bad for a while. With brown rust color. I replaced my radiator, thermostat, new upper and lower hoses. Everything runs great but I have no heat. I flushed everything including the heater core. Core is not leaking into cab, and both heater hoses are cold. What should I do next FYI heat worked great until 5 days ago.
View 14 RepliesI'm trying to figure where the coolant leak is. Appears to originate on the driver's side front, right near the thermostat housing. Since the engine tilts back the entire drivers side is wet. The thermostat gasket appears to be OK, but it does have a lot of miles on it.
If it's not the thermostat then can coolant leak from the cross over tube. And is the cross over removable without taking off the intake. There appears to be a bolt coming up from underneath on the passenger side.
Also, does coolant flow through this plastic intake. If it does, then the leak could be some where else, if not, then it's probably the thermostat.
Tried to flush it and got as far as draining everything. I can't hook up my T and begin the flushing process because I can't remove the thermostat. I have a buddy who can get the bolt out but I'd have to be able to drive the truck to him. I've tried just about everything to remove it. I did manage to find some replacements for when I do get the last one out though .Is there a way to still flush this thing like maybe just hook up the hose to the t and run the engine with the heat on to open the thermostat?

View 1 RepliesThe truck has been a dream for several months and I had a coolant leak at the thermostat outlet. Changed the fitting and thermostat and sealed with lots of blue monkey snot. It's been perfect for a couple months but a week ago it started leaking again. Exactly the same as last time. I cleaned the mating surface of the water pump with a plastic scraper to remove the old sealer and then finished it with fine scotch brite. I looked at several parts breakdowns and none of them showed a gasket.......

View 1 RepliesI have a 97 F-150 that the A/C went from blowing cold to hot instantly. I have done the following;
1. Checked fuse. Was good.
2. Checked Low Pressure connection.
On this, I jumpered the connector and could not get the clutch to engage. I also checked to make sure I had 12v from that point, which I did.
3. Checked the power to the clutch assembly. Got nothing. I also put 12v directly to the clutch and it poped in just fine.
Based on all of this I think I have a bad relay between the low pressure sensor and the clutch assembly. The only problem is I cant find it. Where this relay is located
2001 5.4l Windsor... I have been reading up on some post, and I'm wondering where the EGR VALVE is located on these motors?
View 5 RepliesI'm looking for information and possible photo location for the blower motor resistor. My truck has climate control. I've looked under the dash on the passenger side and behind the glove box door and I've been unable to spot the location. Do I have to remove the plastic panel behind the glove box?

View 2 RepliesSo I tried to replace my thermostat and housing and the housing bolt snapped off. Ok so I tried to extract that bolt off and the extractor bolt snapped off inside. I am guessing it might just be easiest to replace the water pump now? I am pretty much at the end of my mechanical rope which is short anyhow.
View 6 RepliesHad a question about where the battery fuse is located and it's number. I just put a brand new alternator on.my truck. Turns out I might not have needed one, switched the battery with the new alternator on and the truck still went dead after it ran for about 10-12 seconds. So some told me it may be the battery fuse but I don't know which fuse it could be.

I'm trying to locate the sensor for the Automatic Head Lights.
I had a small "spill" on the dash at night and immediately the lights started to blink and click. It fixed itself but sometimes it will do a weird little "click, click noise" change thing. I would like to clean the sensor or ensure it's not partially blocked.
Locating subject relay on my F-150 XLT Extended Cab, 4.6Ltruck. All my research thus far indicates it is somewhere on the truck. An electrical diagram I've come up with shows it in the "Blower/Flasher Relay Block". So my question is exactly where is the Blower/Flasher Relay Block?
View 4 RepliesF250 LD 99. Battery light flashing from time to time. When it happen voltage gauge in dash go up (but not in red zone so far). All other light are blinking too but not on and of like battery warning light then like stronger - weaker. So far at Internet is said should be ground. I saw one ground at firewall close to negative post of battery but where is other ground? Can it be voltage regulator (alternator)? Did clean battery posts, didn’t work. 4,6 engine. Voltage at battery posts with engine on is 14,7 - 15,1 V. With engine off 12,3 V.
Didn't managed to check voltage when is battery light flashing as it only happen when I drive not at idle.
I am in the process of re-assembling a 97 F-150 that was disassembled by someone else. Looking for photos or reference as to where the bracket for the parking brake should be located and how? It looks as if the bracket connects to the front leaf spring hanger, but I'd like to see a photo of it in position as well as routing of the cable around the spring and axle. I'm concerned with re-installing it and having it in a position where it will bind or get pinched.
