2004 Ford Explorer

Shakes the whole vehicle violently

2004 explorer 4×4, new brakes and rotors all the way around. After a short time (after replacement) when brake pedal is slightly applied, a noise comes from the rear, and literally shakes the whole vehicle violently. The noise sounds like it’s coming from RR. I took the tire off, and found a broken stabilizer link and thought maybe that was the problem. Repaired that, but it’s still doing it. Any ideas?

Sounds like a caliper is hanging up or sticking. But Since you just had new rotors put on one other thought comes to mind. If the rotors were not carefully cleaned before installation it might be the cause.

Clean brake rotor

As shown in Step 11 in our step by step brake pad installation guide, the rotors need to be cleaned before installation. There is a coating placed on the outside of the rotors to prevent rust while setting around on the shelf. If this coating is not removed it tends to gum up the brake pads and will create havoc. Noise and pulsation being the number one cause of not getting the rotors properly cleaned.

Ford Escape

Blows hot air then back to cold

Turn on air conditioning blows hard cold air and after a few minutes blows hot air then back to cold after awhile.

This may be from the air conditioning system being low on Freon. You can listen for the compressor to cycle on and off. When the Freon gets lower than normal the compressor tends to cycle on and off more frequent. If this is the case, a top off may be in order.

2006 Ford Taurus

Sputtering down the highway

I just bought a 2006 ford Taurus from my daughter and she said that it had been sitting for awhile. It had an 1/8th of a tank of fuel in it. I put fuel injector cleaner in it and filled it up. The car drove fine for a couple of days and now it’s sputtering down the highway?

Since the car has been sitting for a while the fuel that was left in the tank may be weak. Adding a half of tank of high octane to what is already there will help bring the octane level up. If the fuel is what is causing the sputtering then this should help. Besides, you have to put gas in it anyway so it is an inexpensive test.

The sputtering may also be caused by failing ignition components. If the check engine light is on, have the codes extracted and post them below for more details. A basic tune up may be all that is needed but make sure there are no codes first.

2002 Ford Explorer

Doesn’t blow cold air

The air conditioner when you turn it on blows air it just doesn’t blow cold air like it is supposed to. My question is in this case would this most likely mean it just needs to be recharged?

In most cases yes. But the question would be why does it need recharged. There is a leak present in order for the Freon to leak out. So some shops may recommend charging the system. Then you can drive it around and see if it lasts for the entire summer or the afternoon.

I have found in most cases that replacing air conditioning compressor and all that is required with doing so takes care of 99% of all the leak issues. When the air conditioning compressor is replaced the system has to be flushed and all o-rings replaced. It is also required to replace the accumulator and orifice tube for the warranty to cover the compressor. Once all of that is done and recharged, you should be good to go.

The refrigerant system incorporates an A/C compressor controlled by an A/C cycling switch.

The A/C cycling switch senses evaporator core pressure to control A/C compressor operation.

An A/C compressor pressure relief valve is installed in the compressor manifold and tube assembly to protect the refrigerant system against excessively high refrigerant pressures.

An evaporator core orifice tube is installed in the condenser to evaporator line to meter the liquid refrigerant into the evaporator core.

2003 Ford Focus

What type of shop would be best to get the cylinder head replaced?

I just had check engine light repair. I was told EGR valve is clogged, this is the 3rd EGR problem with this Focus, two previous valves were replaced. What can be done to minimize this reoccurring problem. I see repeated problems Ford SPI engine dropped valve seat-problems, can you please tell me how what type of specialty shop is best to diagnose this problem?

If it is the dropped valve-seat problem and the top end the valve seats come loose from the cylinder head and drop into the cylinder and if it’s in little chunks then they sometimes they can blow out your exhaust pipe and be okay and you just kind of it smokes and you have the cylinder head replaced. What type of shop would be best to get the cylinder head replaced since I think that is what I need. What type of machine shop would service machine shop cylinder head valve job? Since Is it better to get another engine that to have the cylinder had valve job done?

You can do it yourself if you have the tools and knowledge of taking off the head. However I do recommend sending out the head to a machine shop. Just about any local auto parts store will generally have an in house shop they use. So just get a hold of them and they can get you a price and turn around time. Depending on mileage would determine if I would replace the entire engine or not. Therefore I might even just replace the entire car.

Ford F100

Slowly heats up

I have an older pickup, it will maintain a good temp just driving through town, but if I let it sit at idol, or drive it on the highway it slowly heats up to overheating, I have changed the water pump and that seemed to slow the process but it still does it, it also has a new thermostat. No leaks that I can see, any ideas what my problem could be ?

Your Fan is no longer doing its job or the fan shroud is missing. Your vehicle may have had an aftermarket flex fan installed in place of the factory clutch fan. This situation may also occur if the thermostat is removed or stuck open.

Flex Fan

Another helpful accessory for vehicles using a belt-driven radiator fan is a flex fan. These fans are large diameter units designed to provide more airflow at low speeds, by using fan blades that have deeply cupped surfaces. The blades then flex, or flatten out, at high speed, when less cooling air is needed. These fans are far lighter in weight than stock fans, requiring less horsepower to drive them. Also, they are far quieter than stock fans. If you do decide to replace your stock fan with a flex fan, note that if your vehicle has a fan clutch, a spacer will be needed between the flex fan and water pump hub.

2001 Ford EscapeMy dashboard has this foggy/moisture look going on. I believe it is on the inside as a wipe of a finger does nothing. How can I clean/fix this? Or is this something with my defroster seeping in? FYI, car is still under warranty if it is some kind of leak. Thanks in advance!

If the car is under warranty you may be best served by contacting them and letting them know of the situation. They should let you know if this is something that is going to be covered under warranty. I would not touch it until you contact them.  If they decide not to cover it then you will need to dig into it deeper. Moisture on the inside is not very common. Disassembly may be required.

Foggy look

Generally the only thing that will create a foggy look is an evaporator core leaking. And this will create a foggy look on the inside of the windshield.

1976 Ford F150I have no spark, already changed ignition coil, ignition module, pick up coil, spark plugs,wires, and distributor cap. I have 12 volts at the coil but when i put a good spark tester on i get no spark. I’m at my witts end please help

The next step would be to check the wiring harness. Being as old as it is the wiring may have become damaged. Also check and clean any ground connections. Use the wiring diagram to help trace and check the wiring on your vehicle.

 Ford EscortCan I put a 1.9 4 cyl with transmission from a 1993 ford escort Lx into a 1998 ford escort se..? If i can…will i have to change or modify anything ?

Simple answer. No

Long answer. Anything is possible. You would have to change the computer system and wiring and mounts and exhaust and sub-frame and, and more work than it is worth in my opinion. Then you would be looking at being held to a different standard when it came to any emissions checks.

Here are the wiring diagrams for the transmissions for both vehicles for a quick visual comparison.
