How do I change the Serpentine belt on a Ford Scorpio?

DRIVE BELTS

The tensioner used by Ford consists of a large clock spring wrapped around one bolt, engaging in an arm on which a pulley is mounted. Because the action of the spring is anticlockwise, when engaged the pulley pulls the drive belt at a pressure set by the spring. As the drive belt lengthens with wear, so the spring takes up the slack. Because of the constant tension drive belts last for years, but they should be checked regularly for signs of wear. The belt might become cracked across its width, normally in the grooved face, or it may become glazed or frayed in appearance.

NOTE: If the drivebelt tensioner(s) are in good order then they will swivel about the fulcrum bolt quite easily using only medium force. However, if the tensioners have corroded in place then considerable force may be required to release the tensioner - in this case additional leverage may be required and care used to avoid injury.

1997 pathfinder 3.3 v6 motor. i am getting no fire at all

QUESTION:
i have a 1997 pathfinder 3.3 v6 motor. i am getting no fire at all. i know there is a crank sensor and the dist. can anyone tell which is more likely to be the cause? i have some people tell they are bad for the dist. and then others tell the crank sensor

ANSWER:
The Cam sensor is the most common on that year Pathfinder. That is the one in the distributor. With no spark conditions, thats the first place I check! The way I check it is with a multimeter. I check voltages and grounds. If I have them, then it's normally the distributor. ( B/W wire = Battery voltage & B wire = ground.)Are you able to scan for codes? That would definitely help which it could be. I have really never seen those crank sensors fail, where I have seen distributor fail. I have also seen allot of New after market distributors not work also. Not to say that may happen to you, but please keep that in mind if you decide to go that route.

When I tried to start it both batteries were dead.

QUESTION:

I needed to move my truck to another location so I could work on the speedometer problem. When I tried to start it both batteries were dead. A battery charger was connect but with reversed polarity. Before I could stop it the charger was tuned on. I immediately turned it off and disconnected it. I've charged the batteries but now the truck won't start. I found a 10 amp fuse burnt (in a panel in the engine compartment). When I changed the fuse some light on the dash panel came on - in a dim state- and stayed on, until I removed the fuse. The truck won't start although it will turn over. The ignitor light does not come on any more. This is a 1999 E-450 cube van with a Power Stroke Diesel. Can you shed some light as to what might have happened to the electronics of the truck My biggest fear is the computer.

ANSWER:

Because you hooked your charger up backwards it likely you blew one of the fuse links at the starter solenoid on the passenger side inner fender. I'm enclosing a schematic for the fuse links. Take a 12 volt test light and move down the harness where the fuse links are located and check for 12 volts. I suspect you have blown one or more.

How to Scan for Trouble Codes (Check Engine Light)

How to Use an Engine Scanner The engine code scanner has made automotive repair easier than ever. When the check engine light comes on while driving it means there is a system that is having a problem. With the trouble code scanner you are able to retrieve the trouble code stored in the vehicles computer. Once the system has been identified replace the shorted senor or other repair and clear the codes out of the vehicle's computer. Once the codes have been cleared the computer will go into relearn procedure and run any number of system monitors to determine if the trouble has been properly repaired.

When the Check Engine Soon Light comes on , your first instinct is to pull over and check out the situation. This is not necessary. This is the vehicles way of letting you know at its earliest stage that an error has occurred. No need to panic. If you have been driving with that all annoying light on, remember this : Your gas mileage will improve if the necessary repairs are made.

My 2000 Caddy Dts is over heating. Yes it has a blown head

QUESTION:
My 2000 Caddy Dts is over heating. Yes it has a blown head gasket no doubt. However I want to solve the overheating problem that blew the gasket. The car overheats in 20 minutes. The upper radiator hose has burst twice. The water pump and thermostat are both new. I don't understand why there is enough pressure to burst the hose but not not venting from the reservoir cap at 16psi. Should the cap blow first before the hose. I feel there is a blockage some where. Can anyone help me with how the coolant flows so maybe i can find the blockage if there is one.

ANSWER:
From what you have stated, the problem would be the radiator cap. The cap should open at 16 psi and since it busted a hose, it had to be over 16 psi which means the cap should have opened up to releave the pressure into the overflow tank.

Engine Cooling System

the clutch pedal stuck down to the floor.

QUESTION:
2004 Mini Cooper S, I started driving and the clutch pedal stuck down to the floor. I could not shift gears. I was able to pull the pedal up with my foot and drive the rest of the day with no problems. Today, it stuck to the floor again and I had to pull over because I could not shift gears. Once again, I could push the pedal back up with my foot and make it home. However, my husband notices something leaking when I pushed the clutch in and out.

ANSWER:
The leak you are seeing when you push the clutch is hydraulic fluid. The clutch is similar to the brake system in that they both require hydraulic pressure to be actuated. A leak such as the one you are seeing will definitely prevent you from being able to shift gears. Check the fluid level in the clutch reservoir which is under the hood close to the fire wall. If the fluid is low, you need to find out where the leak is coming from. The leak will either come from the clutch reservoir, the clutch cylinder which is attached to the pedal on the engine side of the fire wall, the slave cylinder which is in the transmission bell housing, or one of the lines that connects these components.

Low Engine Oil Light came on when I started my car this morning

QUESTION:
I have a 2000 Monte Carlo SS, 92K miles. I change the oil regularly between 3K - 4K miles. I check the oil three to four times in that interval. I have never had to add oil. I have never noticed leak spots under the car. This morning, when I started the car the Low Engine Oil Light came on. I shut it off, checked the oil and it was low. I re-started the engine and the light did not come back on. What's up with this?

ANSWER:
Either you have a new leak or the oil change place did not completely fill the oil. Sometimes the low oil light will come on when the oil is not low, this would indicate a faulty oil level sensor.

it ran hot on me last night and also made a few noises

Question:
I have a 99 cougar 6cyl and it ran hot on me last night and also made a few noises and went dead on me,i crank it back up and got it home and popped the hood there were smoke coming from the coolant jug.what could be some diagnostics for this problem?

Answer:
You need to check the coolant level once the vehicle has cooled off. Here are the main reasons a vehicle will overheat.1. Faulty thermostat - Thermostat is usually located before the radiator inside the upper radiator hose. When the temperature of the vehicle gets to "operating temperature" the thermostat will open, allowing coolant to flow through the radiator, where it's cooled.2. Faulty water pump - The water pump helps build up the pressure to make sure the coolant will is flowing. Coolant can become restricted.` 3. Restriction in Radiator will comprimise coolant flow4. radiator fans keep the radiator cool when the vehicle is not moving. If they do not activate at idle, the vehicle can overheat.

I recently replaced the alternator

Question:
I recently replaced the alternator in my 1997 GMC Sierra. However, when I initially start the truck it still cranks on the starter initially. The starter is good, so I believe there may be a problem in the fuel injection system. Until I can get that checked out though I have received two pieces of conflicting advice about how to keep from ruining the starter and I was wondering which is the better of the two. 1) use starter fluid 2) run fuel cleaner every tank of gas

Answer:
I would have a fuel pressure test done and see what you have for pressure, if the pressure is low the truck will be hard to start. You can run fuel injector cleaner about every 3000 miles i would use and injector cleaner called chevron techron. As far as I'm concerned its the best stuff for cleaning the injectors and the upper intake system, I wouldn't keep using starting it can cause damage over time.

gmc pickup speedometer shows zero

Question:
2004 gmc pickup speedometer shows zero and abs light and servivce brake lights on trani shifts goofy like truck is not getting road speed signal

Answer:
All these problems are related to not getting a signal from the vehicle speed sensor. The proper way to test this is with the use of a scan tool,checking for codes and reading the sensor outputs to the trucks computer. I will send you a picture showing the sensor location,it is #4 in the illustration, you can check to see it the wiring to it is intact. The sensor is held on by one bolt,and easy to replace. It cost approx. 25.00. But replacing it with out the testing is a gamble.
