1992 Chevrolet Tahoe timing

timing on the chevy motors do not very much.
most of the older 350's timing are set about 8 deg before top dead center. some california smog certified 350 timing were set back to 0 deg or, at top dead center. check under the hood for a smog decal. it should have the timing specs, or it might say "timing not adjustable" or N/A. if it is missing the decal i would set it at 8 deg, road drive it, and listen for enging pinging on accelerating under load. if no ping i would leave it at 8 deg,if there is slight pinging i would ****** the timing in 2 deg increments until the pining stops. i would stop if i reach reach 0 deg or top dead center.

Need to know what the degree the timing should be for a4.9 Cadillac Engine ?

The 1991 Cadillac DeVille 4.9 engine incorporates a magnetic timing probe hole for use with special electronictiming equipment. Malfunction codes may be set during ignition timing adjustment procedure.Enter diagnostics and clear trouble codes if this occurs.#1 Place transmission in park .#2 With the ignition in the Off position attach a timing light to #1 spark plug cable .#3 With engine at normal operating temperature and air conditioning OFF,take off the air cleaner upper housing. The engine should be OFF at this point.#4 Jump pins A and B at the ( ALDL) connector.while not in diagnostic display.SET TIMING MODE message will apear on the climate control Driver Information center.#5 Start the engine and aim the timing light the timing mark loosen the distributor hold-down nut. While observing the timing mark, rotate distributor untill the line indicates the correct timing .This sets the base timing at 10 degrees BTDC at any speed under 800 RPM in the (PCM) The PCM controles the timing throughout the intire engine RPM range.This is the best imformation I can offer you good luck.

I have a 1991 Mistubishi Galant and it needs an alternator what information would I need to know about the motor in order to get the alternator? I don't know any of the information and hoping you could...

You will need to know the motor size or number of cylinders. I believe it only came with a 2.0 liter, but I may be mistaken. They may want to know if it is automatic or standard transmission and if it has A/C or not. They will ask what model Galant it is also, base model, GS, GSR, etc.

How to set timing on a 1987 chevy c10

The decal under the hood is the best place to look for the specific instructions, but depending on which engine you have you will need to disconnect a wire terminal, and then set the timing as usual with a timing light. The decal usually gives the connector location and wire color. If not what engine do you have?

You didn't mention which engine you have but I'm going to guess you have the 1.8L 8V, but you can refer to your "Emissions Control" label in the engine compartment for exact timing specs. You will need a timing gun to get it right on,by marking the timing mark on the fly wheel you will need a 27mm hex end tool to remove the plastic timing cap on the transmission to expose the timing mark on the flywheel (unless it is already gone like most old vdubs). There is alot of variables depending on which engine you have I recommend picking up a "Haynes" VW repair manual it has all the info for setting timing correctly. If your vdub doesn't have the Emissions Label just call up any Volkswagen dealer give them your car info and they can give you the degrees of timing. Good Luck
