TIMING BELT QUESTIONS ON THE 2.0 SOHC

1999 Ford Escort

Engine Mechanical problem
1999 Ford Escort 4 cyl Front Wheel Drive Automatic 122700 miles

I'm planning on replacing the timing belt myself when the weather breaks. My question is when installing the new belt how do I put it on without moving the camshaft? I did read that its supposed to installed at the crank 1st and the other pulleys. That's my biggest fear since I don't want to throw it out of time. If I do mistakenly move it does it matter which way I turn the cam to reline it?

Another question is the tensioner is spring loaded like the drive belt tensioner? I read up that you can move it with a allen wrench without loosening the bolt and put the drill bit in to keep it in place.

Last question is when I take off the crankshaft pulley, will the engine turn to the left a little? I keep hearing that if you turn it that way, it can cause damage. When I do get the pulley off, can I put the bolt back in to line up the marks?

This is my 1st time ever doing a timing belt since i'm mechanically inclined on most other general repairs so that's why i'm asking all of these questions. Thanks in advance.

Hi, this is simple . First line the marks up mark them with white paint or yellow. Next remove the accessory belts a/c p/s alt. Remove the crank pulley put the bolt back in the crank. Line the marks back up. Release the tensioner. Remove the timeing belt. Install new one crank first put the slack in the belt on the tensioner side release the tensioner. Turn eng over BY HAND 2 OR THREE REVOLUTIONS. TIGHTEN THE TENSIONER. Put bottom cover on and crank pulley check marks one more time. Start eng if runs normal. Install the rest of the parts. Good luck billymac

Damn that was a fast repsonse. Thanks again for it. So I won't damage the engine by turning it clockwise while removing the crankshaft bolt huh? If that's the case thats a good thing.

On the tensioner, I thought it is an auto tensioner like the drive belt one. I found out that you can just use the allen wrench to turn it without loosening the bolt and put the bit in to lock it. I also saw in haynes that the spark plugs have to be taken out. From what I see, people skip that step.

Oh yea two more question, when I replace the water pump, is it easier to remove the tensioner? And is the camshaft easy to move(like spinning freely like a wheel)? Like I said I don't want to throw the cam out of time. Thanks again.

Yes you will not hurt the eng by looseing the bolt however you will have to hold the eng to loosen that bolt anyway an impact works great for that. Yes I take the tensioner off to replace the pump. No the cam does not spin freely valves open and close it will not spin by itself and if you mark it from the beginning you never have to worry. Although eng damage is not likely with this eng and all overhead cam engs. You must use caution. The spark plugs. Yes the proper way is to remove the spark plugs. And no I don, t if any at all just the number one. So I can make sure it is on compression stroke. Hope this helps billymac

Billymac. Thanks for answering all of my questions. I really do appreciate it. I think I feel more confident doing the job.

So the cam takes almost as much resistance to turn as the crankshaft right? You told me they are turned by the valves.

You didn't answer the question on the tensioner lol. Is it automatic(springs back and forth like th drivebelt one)? Like I said I keep reading that it is and you told me that I have to loosen the bolt to move it so i'm confused. Thanks again. I hope i'm not driving you crazy with this lol.

Hi irfman2000,

billymac gave you great info and good advise.

Just thought I'd through in some Removal and Install instructions along with a couple pic's to help out.

Hey obxautomedic thanks for the reply but i've already read and studied the book but all I needed to know is that when I take off the belt if I can just turn the tensioner pulley with the allen wrench without loosening the bolt? That's what I keep reading up on. It never said to loosen the bolt according to the haynes manual. So I guess its not an automatic tensioner huh?

No, you will have to loosen the tensioners.

Take a look at my post above at the remove pic.

Yea I understood the print you sent me but I keep reading that it is spring loaded. In that case why does it say to stick a drill bit or something thin to hold it back? Shouldn't stay back by itself since you gotta loosen the bolt anyway? It if doesn't stay back by itself should I mark where it was originally at then remove it? Sorry i'm just trying to get this straight here since the timing belt thing is new to me.

Oh yea on the camshaft, it does take a lot to move right? I just dont want to throw that part out of time when I slip the new belt on. Thanks again.

Yes, it is spring loaded, No the tension when you loosen the bolt the tension goes in the direction of the belt making it tighter.

No, you don't want to mark it. With the new belt it may make it to tight or to loose. Not all belts are exactly the same size and that it why a tensioner was put there.

As far as the Cam movement, it doesn't take as much to turn it as is does for the Crank. You can move it with your hands, It gets hard once it opens a Valve. If you move it around a little (Clock Wise or Counter Clockwise) it will not hurt anything.

Also, since you will be there already are you planning on replacing the Water Pump.

Here is one thing you can do.

Before putting it all back together. You can start the vehicle just Don't Run it more than 5 -10 seconds. Do make sure your radiator hoses are connected. And have someone start it for you while you watch the timing belt because it does have a tendency to walk off since the cover is not there to keep it in place.

And to be honest they can be a pain getting back on you will just have to work it.
