| PARTS DEPARTMENT
|
|
Our Parts Department is stocked with all of the solid
name brands you have come to trust for reliability. In some instances, we have more than one quality
brand available for your repairs. We carry name brands, such as:
- AC-Delco,
- Motorcraft,
- Gates Belts and Hoses,
- Anco Wiper
Blades,
- Borg Warner,
- Pennzoil,
- Castrol,
- Mobil 1
and many, many more.
We only stock the best because
we want you to be satisfied that your repairs are reliable
and covered by factory warranties. These
companies all have OEM equivalent or better
products to fit your automobile or truck. They
fit right, the first time.

| Parts in an engine. |
This
description is for a typical engine, there are many
variations in design.
1. Head: The
passages shown carry engine coolant. (water / antifreeze
mixture). Sometimes, the gasket between the head
and the lower block of the engine will develop a
leak, and need to be replaced. You may have heard
of a "bad or blown head gasket".
2. Push rod: The top of the push
rod aligns with the rocker arm assembly, and the bottom
with the lifter (or valve lifter) When the camshaft
turns (6), it pushes on the lifter, which pushes on
the push rod, then the rocker arm, and opens the valve
(3). Push rods are not used on overhead cam engines,
where the cam is on top of the engine, and operates
the rocker arms directly.
3. Valves: The engine shown has only 2 valves per
cylinder, some engine designs have more. An intake
valve opens and allows a fuel / air mixture go be pulled
into the combustion chamber below. As the engine rotates,
it closes, the piston (4) comes up, compressing the
mixture. A spark plug (normally at position 9 ), ignites
the mixture and the burning gas / air expands and pushes
the piston down -- which turns the crankshaft (7).
After the mixture burns, the piston again goes to the
top of the cylinder, and an exhaust valve opens. Hot
exhaust gas is vented out the exhaust manifold, to
the exhaust pipe, catalytic converter, muffler, and
tail pipe. The crankshaft connects to the transmission
via the flexplate or flywheel.
4. Pistons: move
up and down in the cylinders. The first piston is shown
about at the top of the stroke. The
top position is sometimes referred to as Top Dead Center. You
may have heard of an ignition timing specification
such as 7 degrees BTDC. That refers to a crank rotation
that is 7 degrees Before Top Dead Center. The timing
specification is a number mesaured in degrees that
refers to the time the spark plug fires relative to
the top of the piston position. (In the example when
the crankshaft rotates 7 more degrees, the piston will
be at the top. ) The spark plug fires before the piston
reaches the top to allow time for the fuel / air mixture
to start burning. The circles around the tops of the
pistons are piston rings. They provide the function
of sealing the fuel and air in the area above the piston,
and keeping oil below the piston.
5. Timing chain / timing sprocket: The
timing chain runs off of the crankshaft, and is aligned
with the crankshaft to rotate the camshaft (6) to open
and close the valves at the appropriate time. Many
newer cars use a timing belt (often used on overhead
cam engines). Timing belts are normally made of a rubber
compound, and require periodic replacement.
6. The
irregular shapes on the shaft are the cam lobes.
7. The crankshaft: connects
to the pistons via the rods. A pulley is often on the
crankshaft on the front outside of the engine. Some
cars have sensors mounted by the pulley on the crankshaft
to provide a signal to the engine computer.
8. Valve springs: push the valves
closed, until a push rod or cam pushes them open.
9. Spark plugs: go here, and the
tip extends inside the engine combustion chamber. A
high voltage spark ( 30,000 volts or more ) delivered
to the spark plug by the ignition system ignites the
fuel / air mixture.
10. The push rod: shown from the
top side. On the opposite end of the rocker arm on
top of the push rod is the valve stem.
11. The oil pickup: has a screen
and is located in the bottom of the oil pan. If you
don't keep your oil changed often enough, this can
become covered with sludge formed from the oil and
contaminants ( sludged ) or restricted, and all the
other parts of the engine that require lubrication
by the oil may not receive an adequate supply of oil.

| To Calculate
Miles Per Gallon |
1. Take
current odometer reading.
2. Fill up your tank and write down how many gallons it took.
3. Drive the tank to just about empty.
4. Fill up again and write down how many gallons it took.
5. Before leaving the station note how many miles you drove
between fill-ups.
6. Divide the number of gallons used into the number of miles
driven between file-ups.
EXAMPLE: (24,785 - 24,475) = 310 miles driven on the tank
since the last fill up.
310 miles / 10.2 gallons used = 30.4 miles
/ gallon
Note this only works properly using fill up to fill
up, since putting less than a fill up would not tell how
much fuel was used to arrive at the same reference point

| JUMP-START
YOUR CAR |
| The
first thing you want to remember when jump-starting a car
is that a slight possibility of explosion does exist.
This is because hydrogen gas--which forms as a battery
discharges and loses its fluid--is flammable, and a spark
from the battery cables could, theoretically, set it off.
We emphasize slight because the gas would
have to be fairly dense around the battery for this to
happen. This is unlikely unless the battery has been sitting
for a long time and little or no air circulation has occurred
in the area, but it is possible.
Here are few simple
precautions to avoid a serious injury:
- Wear protective goggles during all phases of the procedure.
Keep a pair attached to your jumper cables.
- Put out cigarettes before opening the hood. Use a flashlight,
not a match, to look under the hood at night.
- Be certain the vehicles are not in contact with each
other.
- Do not allow the cable clamps to touch each other.
- Attach the positive (+) cable (red) to the positive terminal
of the dead battery first. Then attach the other end of
the positive cable to the good battery.
- Attach the negative (-) cable (black) to the negative
terminal of the good battery. Then attach the other end
of the negative cable to the engine block away from the
negative terminal. Do not attach a cable to the negative
terminal of the dead battery.
- Once the engine is started, carefully remove the cables
in reverse order, again not allowing the clamps to touch.
- Do not lean over the battery during the jumping process.
If an injury does occur, contact your ophthalmologist or
go to the emergency room immediately. |
