The answer below refers to DOHC, the timing marks are different on SOHC. Seen from the front of the car looking backwards, the right cam (left side of car)has a notch on the cam which you position at approx "1 o'clock) lining it up with a line on an adjacent plate in that area. The left cam (right side of car) has a notch which you should similarly align with a plate at approx 2 o'clock. You do this with the crankshaft sprocket aligned with a mark on the oil pump at 3 o'clock. The timing belt goes on with the cam- and crankshafts at those positions. The belt itself goes first around the crankshaft, then the idler bearing, then the right cam, then the water pump, then the left cam, then the timing belt tensioner. Hold the belt on these pulleys with paper clips (big fat ones that hold a stack of paper). Tension the tensioner. In this process the cams may have turned a bit off their marks, so go back and do it again until they align with their marks right. Then remove the clips and turn the engine and see that all is well. Note: I assume in the above that you will have the approx alignment correct before removing the old timing belt. The tensioner has a certain clearance (approx 0.2 inches) which must be set up right. That's the clearance between the lower pushrod part and the lever arm.

1-6-5-4-3-2

the widest one on the timeing chane cover right in the middel of it

All factory available engines for 1985 Rangers have a CLOCKWISE ROTATION on the distributor

Knowing the firing order of a car's engine can help troubleshoot problems later on. The firing order for a 1993 GMC Sonoma 2.5L engine is 1-6-5-4-3-2.

1-8-4-3-6-5-7-2

1 3 4 2 i believe this is the order, if any question let me know.

1-8-4-3-6-5-7-2 going clockwise around the distributor's top

how do i set the timing on a 1998 cadillac deville 4.6

1-3-4-2 with no. 1 spark plug being on the cam-belt side of the engine and no. 4 plug by the gearbox end.

If its a 1.8, its 123456

First, do not pull the spark plug from the wire itself as you'll distroy it! do it from the boot or even better get yourself a spark plug wire puller ( yes, it exists in auto parts stores). If done with no puller, grasp the boot and twist it gently side by side until it begins to turn, next pull it gently straight away from the spark plug, this will do the trick. Next, you'll need a 5/8" socket to remove spark plugs,as well as some 3/8" extenders (flexible and straight ones).You may need to work from inside the tire well to remove the plugs on the left side.The ones on the right engine side are ok to work from the hood. As with most screws in most engines, they are removed by turning counterclockwise( believe me, this is not too much information for some who asks this question).Check/replace, gap accordingly plugs and reinstall with antisieze compound(buy it from auto store, you will need it when replacing oxygen sensor,too) so you won't damage the thread when reinstalling. Attach the wires to the proper cylinder,or even better, do one at a time to prevent wrong connections.Check for proper engine performance. Good luck!!

i`m not sure about the timing because there`s either a straight 6 or the hurricane 4 engines for that year,carburated of course. if its misfiring, it could be due to the plug wires .they might be incorectly in stalled on the distributor.it could also be dirty fuel and/or air filters. i would check the filters first(air) ,then check to see if the plug wires are in the right firing order on the cap. if your still having problems let me know, i`ll see if i can help.thanks,walt

long envolved process. buy the service book from advance or auto zone and READ and get very familar with every step involved.then you will understand why they charge $400.00 to $600.00 to do it.

Never heard of a 4.2 liter engine.

Neither. The timing should be set to factory specifications.

it should be cast somewhere on the intake.

The firing order should be 1-8-4-3-6-5-7-2.

According to a chiltons manual for a 96-00 prelude the firing order is 1-3-4-2
