How do I reset the timing?

First pull the timing belt tensioner then slip the belt off the cam gears. You then need to find TDC (Top dead center). 3 ways to find TDC 1) There are marks on the crank pulley align them for TDC. 2) Remove timing cover and use crank gear mark seen in link below 3) Put the dip stick in cylinder 1 and turn engine until dip stick stops going up. After finding TDC align cam gear marks seen in link below. Now make sure both cam and crank stay in position and slip timing belt back on (you can move the cam gear to get the belt on but make sure the marks are aligned after the belt is on). Last tighten the belt tensioner, I usually use my finger or an extension to get some more tension on the belt. You might have to remove engine mount bracket makes life much easier as the front cover section is TIGHT !!!. Turn engine a few times to make sure you have compression and engine turns without getting stuck. See link below good luck.

Timing belt replacement Zetec engine with VCT. Part 1

IMPORTANT The ZX2 Zetec is a non-interference engine. This means the valves are not capable of touching the pistons at any time. If your belt breaks, there will not be any valve damage. There are reliefs cut into the top of the pistons that allow clearance for the valves if the belt breaks. Most engines are interference and will cause several hundred or even thousands of dollars of damage when a timing belt breaks. Most shop manuals list the ZX2 as interference but it is not. Many people seek out this how-to because a mechanic has informed them that they have valve damage and quoted a repair price over $1000.
This can be done by people that can change their own oil. But, if you have any doubts about yourself then it would help to have someone more experienced then you to help. The average you can save doing this yourself, $250-350.

A. Cam lock tool. Can be made from flat-bar stock (9" long, 3/4" wide, and 3/16" thick) or bought at some part stores.

B. Metric socket set and box end wrench set. You will only need the 8 mm, 10mm, and whatever size the crank pulley bolt is, I think that is 19 mm.
C. Jack and jack stand of course.
D. Lug nut wrench or equivalent socket to remove the wheel.
E. Large adjustable wrench.
F. Set of allen wrenches.
G. Haynes or similar manual for torque values.

Getting started:
1. Put the passenger side of the car on a jack stand and remove that wheel. Remove the plastic splash guard that covers the bottom of the car and the passenger side. These are 10 mm bolts.
2. Remove the serpentine belt then remove the crank pulley. This can be done without an impact gun. Use an impact gun if you have one, but if you don't, then follow this procedure. Use the correct socket for the crank bolt (I think it is 18 mm) with an extension and breaker bar. Put the breaker bar and socket on the bolt and brace the breaker bar against the lower control arm. I used another jack stand and a few small boxes. The idea is to have the bar snugly pressed against the control arm and propped up from underneath so it sits square with the crank bolt. Now, dis-connect the 3-wire connector at the ignition coil so the car won't actually start. Make sure the car is not in gear and no one is standing near the breaker bar. Bump the key about a second in the start position. This should break the bolt loose and now you can go remove it. You can view a video of how to do this here.

3. With the crank pulley off you can now see the timing belt gear. Remove the splash shied cover that is behind the crank pulley. It is held by two 8 mm bolts I believe. Also remove the upper timing belt dust cover. These are 8 mm as well.

4. Remove the valve cover. Start by dis-connecting the VCT connector on top and remove the spark plug galley cover if you have one. These are 8 mm bolts. The valve cover is held on by 8 mm bolts as well. The one on the passenger-firewall side has a stud on it and will require the use of an 8 mm wrench or deep well socket. Do not let the gasket touch the ground. Soak the gasket in WD-40 so it will swell back to original shape and you can reuse it.

5. Now we set the cams at TDC. TDC is Top-Dead-Center. It is the higest point in the cylinder that the #1 piston reaches on the compression stroke. If you have the cam locking tool, it will only slide into the back of the cams (driver side) when they are set at TDC. You may have to rotate the exhaust cam several degrees to get the cam locking tool to slide into the exhaust cam. This is normal because of the nature of the VCT. If you need to rotate the cams to get the locking tool in, then put the crank bolt back in the hole and turn the entire crank with that bolt. After the locking tool is able to fit into the intake cam (firewall side) then use a large adjustable wrench (or 15/16" open-end) on the exhaust cam (there are flat spots near the belt for the wrench to fit onto) to rotate the exhaust cam.


If you are replacing a broken belt or a belt that has otherwise skipped time, then you will have to set the cams at TDC and the crank at TDC separately. If this is the case, then follow the instructions outlined in step 5a. If you do not have a broken belt (you are replacing a belt before it breaks or otherwise fails) then you do not have to set the crank at TDC, it will be set when you set the cams at TDC

5a. If you need to set the crank at TDC separate from the cams then you can do so with a couple of methods. You can remove the spark plug from the #1 cylinder and insert and long screwdriver into the hole. Then you rotate the crank until the screwdriver is at its' highest point. There will be a point where you can move the crank just slightly and the screwdriver will not go up or down. This is TDC for the crank. One final method that has worked for me is to just set the crank key (the small notch the crank pulley slides over) at the 12 o'clock position. Notice that the engine leans slighty forward. Set it at 12 o'clock in relation to the engines lean. It'll look like 12:10 to you. Since each tooth on the crank pulley is about 16* of timing, it would be hard to be off a tooth and not notice.

6. Now with everything set at TDC you can remove the old belt. If the belt has already removed itself (broken) then you still have to loosen the tensioner. Below the intake cam gear you will find the tensioner. It has a small notch on the front with a place to put an allen wrench and a 10 mm bolt sticking out. You have to loosen the 10 mm bolt. It is a small space and this is where a long 10 mm box-end wrench comes in handy. Loosen it about 3 turns and push that allen slot down (it rotates) and this will release tension from the belt. Slide the belt off. To make belt install even easier, loosen the bolt enough to pull the tab out of the back plate. This will give you more slack to work with.

If you have a pre-99.5 with a two piece crank gear, replace this gear with the single piece gear. Part number is at the end of this how-to.

6a. Ford put a TSB that fixed some of the issues with the new belt walking off of the cam gears. The problem is that the new belt would bunch up between the gears a bit when the springs loaded the cams and the VCT was being actuated. The fix is to set the cam gears neutral to the new belt. You'll want to remove the cam locking tool to prevent breaking the back of the cams out. Use a large wrench to hold the intake cam in place while you use a Torx bit (T55 I think) to loosen the intake cam bolt. You only need to loosen it enough so that you can move the cam gear free of the cam. Now, use the wrech and the same bit to remove the oil plug from the VCT hub. Put some rags below the hub to catch the bit of oil that will come out. Now, the exhaust bolt can be seen inside the hub. It is an 'E' (inverse torx) bit. I've always just used a 12-point 16mm socket. Loosen the exhaust cam bolt enough to move the VCT hub (exhaust cam gear) free of the cam. Put the lock tool back into the cams and continue with the next step.

How exactly should the intake cam be set and the exhaust cam be set on a ford 2.0 dohc with VCT.

There is a Camshaft Alignment Timing Tool that is made to hold the cams and another one to find TDC on the crank.

I'm trying to install a new timing belt for my 1999 ford escort zx2 with a vct motor. I aligned the camshafts, did a full rotation and they came out of alignment. How do you align the camshafts with the...

It is normal for the exhaust cam to be slightly off during a rotation because of the nature of the VCT mechanisim. It uses oil pressure to change the cam angle. Since there is no oil pressure with the engine off, it won't stop in the same place every time. Check the links below for more information:

Engine Timing Belt/Chain Illustration
Figure 1
fm1069500554000x.pngBefore installing tool. If the belt broke turn the engine so the #1 piston is half way up. This way you will not bend the valves while turning cams. If you feel that the cams are very hard to turn or stops turning then turn crank by hand to lower piston away from valve. Then turn the cams clockwise or counter clockwise slow one at a time too the proper slot position for the tool to fit. Once the cam marks are lined up bring the #1 piston to its TDC.

You must find the cam lock bar and crank lock pin to do this job properly, otherwise you can bend some valves and that becomes expensive..the front crank damper has a mark to line up with a mark on the timing cover for #1 TDC, but the cam lock bar is what aligns the cams into position. The crank lock pin is helpful but not 100% necessary...

take no 1 spark out and using a long thin screwdriver bring piston up to top then you have tdc,you will have to move cams to get it to come up but iam sure you will have the valves bent from when the belt broke ,remember to turn it over with a ratchet before you use the starter motor ,once timed up the belts hold the cams in place
