1976 Ford F250Do you have a parts diagram and instruction manual for replacing my rear brake drum, or wheel bearings?


RESPONSE

Rear Brake Drum Inspection

Check that there are no cracks or chips in the braking surface. Excessive bluing indicates overheating and a replacement drum is needed. The drum can be machined to remove minor damage and to establish a rounded braking surface on a warped drum. Never exceed the maximum oversize of the drum when machining the braking surface. The maximum inside diameter is stamped on the rim of the drum.

1.Raise the vehicle so that the wheel to be worked on is clear of the floor and install jackstands under the vehicle.
2.Remove the wheel. Remove the three retaining nuts and remove the brake drum. It may be necessary to back off the brake shoe adjustment in order to remove the brake drum. This is because the drum might be grooved or worn from being in service for an extended period of time.
3.Before installing a new brake drum, be sure to remove any protective coating with carburetor degreaser.
4.Install the brake drum in the reverse order of removal and adjust the brakes.

1997 Ford ContourMy Sisters car is a  1997 Ford Contour 2.0L. It stopped blowing hot air and then a couple days later her temp gauge is not going up, the car overheats then shuts off. I changed the thermostat and coolant temperature sensor and it is doing the same thing. Now I find out there is a temperature SENDING unit. If this is bad I understand this could cause the gauge not to work but can it cause the car to overheat?


RESPONSE

The most common cause for your situation would be a leak in the cooling system. The coolant level drops and causes the car temperature gauge to read hot. And when this occurs there is no longer enough coolant to produce heat therefore no more blowing hot air. Until the leak is repaired the cooling system will not work properly as it needs to be able to build pressure.

Temperature Sending Unit

Some engines have a temperature sending unit that is used just for the gauge on the dash. The engine will have a separate sensor for the engines computer. They are both referred to as an ECT – Engine Coolant Temperature sensor. On your engine there appears to be two ECT Sensors according to the wiring diagrams. The one with WHT/GRN and Brn/GRN wires is used for the engine controls. The other with WHT/RED and BLK/BLU wires is for the gauge on the dash.

Looking at the repair manual information it is sort of vague. There is an ECT sensor shown in the Thermostat housing and stated there may be another mounted in the engine block or engine head assembly.

temperature sensor

I have found that sometimes it is beneficial to use a hand held infra-red temperature gauge to assist in these situations. This is better than relying on a gauge that may not be reading correctly.

2013 Ford TaurusCannot find the washer fuse for the Windshield Washer, none found in auto owner’s manual. Washers don’t work, even though wipers do. No motor noise and fluid is full. Where is the fuse? what number is it?


RESPONSE

There is not a separate washer fuse. The washer receives its power from the windshield wiper motor. So if the wipers work, the problem is not fuse related. Either the washer pump motor has failed, the connections or wiring are faulty or the internal relay in the wiper motor has failed.

Mist Wipe/Windshield Washer Operation

When the washer switch (on the end of the stalk) is momentarily pressed and released, a single wipe of the windshield wipers occurs. When pressed and held in, the windshield wiper motor activates the wipers and the wash relay (internal to the windshield wiper motor), providing voltage to the washer pump and directing washer fluid to the windshield. After the switch is released, the windshield wiper motor continues to activate the windshield wipers for 3 additional wipes and then turns the windshield wipers off.

2004 Ford F250I HAVE DONE AN OIL CHANGE ON MY TRUCK AND BOUGHT MOTORCRAFT FILTER FL820S. But when I screw the filter on, it does not fit tightly against the filter adapter. There is a gap and is now leaking. It is not cross threaded and the new gasket is intact.  The old gasket is not still left on. What have I done wrong?


RESPONSE

Oil Filter

Try putting the old filter back on and if it works fine then the problem is with the replacement filter. The Motorcraft oil filter part number is correct. There may just be an imperfection with the filter. It happens sometimes, but not too often with filters. There might just be a slight burr on the threads or something. If you find the old filter does the same thing as the NEW filter now, you will need to look closer. Make sure the adapter threads have not come out to far and do not need to be re-seated.

1999 Ford ExpeditionFirst of all about a week ago my truck was hit from the rear while parked. Consequently It was hit hard enough to push the hitch to one side a bit. Since then, the gas gauge is not registering right and the car cuts out a lot. Hence, Could this be related?


RESPONSE

Absolutely. A hit hard enough to tweak a trailer hitch can cause quite a bit of damage to anything attached. The gas tank is secured tot he frame of the vehicle. So it absolutely has been shaken hard enough to cause the gas gauge sending unit to move. Also, this could have caused damage to the sending unit arm and the fuel pump module that it is connected to. However a more likely reason would be that the impact jarred some internal rust loose. The rust would not have come loose otherwise. Furthermore rust would clog the fuel filter at times and interfere with the fuel sending unit readings. In Conclusion the fuel gauge worked and truck ran fine before it was hit and now it doesn’t. Pretty safe to say it was related since the impact was hard enough to tweak the trailer hitch. .

  • a 1/8 turn type fuel tank filler cap.
  • a fuel filter providing filtration to protect the fuel injectors.
  • fuel lines.
  • fuel pressure regulator.
  • a fuel pump containing:
    • the electric fuel pump which provides pressurized fuel to the engine.
    • the fuel level sensor (9275).
    • an inlet filter.
    • a check valve which maintains system pressure after the pump is shut off.
    • a pressure relief valve for overpressure protection in the event of restricted flow.

The fuel pump is controlled by the powertrain control module (PCM) (12A650) which energizes the fuel pump relay. Electrical power to the pump is provided through the inertia fuel shutoff switch

1978 Ford Pinto PonyI have a 1978 Ford Pinto Pony 4 Cylinder. I would like assistance on setting the Crankshaft and Camshaft timing gears. Since after taking the front off the Engine to replace Timing Chain, Water Pump and Idler it got turned while tightening the Pulleys, etc.


RESPONSE

Place the timing gears “dot to dot”. Align the timing marks so that they are pointing at one another. The gears will only go on one way since there is a key-way that has to be lined up. The chain doesn’t have to be in any particular place as long as the the timing gears line up on the correct marks. Once you have them aligned, rotate the engine a couple of times and make certain the marks line up again. This is a great way to double check the correct installation.

1995 Ford BroncoHow do you remove the Oil Pan on a 5.0 L, and what do I have to disconnect? Have disconnected the Engine Mounts and can not get it high enough to get the pan off. Will I have to disconnect the Transmission?


RESPONSE

You have started down the right track since the engine mounts need to be removed first. The oil pick up tube has to be removed before the oil pan can be removed. The pick up can be removed but it isn’t easy to do. A hand and a small socket or wrench will fit with some tricky hand bending. I’ll post a complete set of instructions for oil pan removal. Furthermore page down to the 5.0L engine for step by step instructions that include some illustrations.

1994 Ford F150 XLTI just replaced my neutral safety switch and starter solenoid starter switch. And when starting my truck up, I discovered that my front fuel tank pump was not working but the back tank was. After some research I decided to change my fuel tank selector switch on the dash and now none of the pumps will work. This is a dual fuel tank system. I then put the old switch back on and same thing none will work. I have checked my fuses and relay and they appear to be fine. About two years ago I had both pumps replaced and the front tank replaced due to the truck sitting for years after Hurricane Katrina. Any pointers would be great.


RESPONSE

I recommend checking the inertia switch first. Should be located under the passenger floor mat toward the top. It is easy to get to and takes only a few seconds to test and or reset. Push the button. Next I would check Fuse O(20A) and then the fuel pump relay.

Ford Focus

Power surge and rough idle.

-It has this reoccurring power surge that causes the idle to fluctuate up and down. This causes the dash to vibrate. It seems to draw power when this happens. You can see the surge or power loss when putting on the brakes. Also when turning on radio heater or a/c and power windows. Its like its starting to die but then starts charging again.

-I have issues when turning a corner and occasionally the transmission will slip or hesitate, then kick back in again and also slips when you step on it a bit to get speed.

The fluid is a clear light red and doesn’t smell burnt, and is right at the level on the stick and as well has had a recent oil change. The plugs were removed and are burning light grey no abnormalities

Tingy Noise

-At highway speeds it makes a humming noise that gets louder as you go faster, like maybe a dry bearing? I checked the coolant and its concentrate was quite high. I think someone put concentrate in without mixing it 50/50, its the ford Yellow coolant. It has a slight tingy noise coming from the top of the engine by the injectors and ignition coils on top.. I had a ODB2 hooked up and the coolant is burning At 77 degrees and as well drawing a fair bit of power through the system.


RESPONSE

Sounds like an electrical issue for sure. If the alternator is not charging correctly for any reason or the battery has an issue I could see this happening. I suspect an internal short in the battery. This would cause the alternator to function abnormally and also not provide adequate voltage to the engine’s computer. This would also explain why the transmission seems to be having issue. Since the fluid level is good and the fluid itself appears clean the issue would most commonly be electrical. I am also going to assume there were no engine trouble codes present since you did not post any and you stated you have an OBD II Scan Tool.

2005 Ford F150 King RanchI have a 2005 Ford F-150 King Ranch with 150,000 miles on it. I have changed plugs but when it is in a pull up a hill it has a miss or a jerk to it.


RESPONSE

This is common to an engine misfire. The typical cause is a failing ignition coil. Since there is more than one ignition coil it is sometimes difficult to pin point. The engines on-board computer, given enough time, will diagnose this issue for you. Once the misfire is detected enough times in a row the check engine light will illuminate. Once the light has illuminate the computer has recorded the exact location of the misfire. Since there are eight ignition coils at over a $100 each, it comes in handy to know which one to replace. No damage will be caused while driving the truck until the light comes on but it may save you some money.

Engine Misfire

When combustion in one or more cylinders does not occur or occurs at the wrong time.
