Title: Timing Belt  Change
Post by: Agent Orange on October 28, 2003, 08:29:05 AM
I've got a 16v motor with about 110,000km. It's time to get the timing belt changed, and valves adjusted. I called a local Suzuki dealer, and they wanted $600cdn to do both. Then I called a Chevy dealer, and they wanted $500 it seems that most of the cost is in labor.

So how tough is it to do yourself ? Are there other parts I need besides the new timing belt ? Also are there any special tools needed ? I'm mechanically capable to perform the job myself, but I've never done one before.

Thanks

I dunno about the 16V, but the 8V is easy.
I don't think you are going to need more
than a belt and a Service Manual.
The 16V is a single cam Engine, should be
similar to the 8V engine.

when i got mine(8V) it had a blown head gasket so i thought it would be a good idea to change the belt too.    If i was just doing the belt it would of been easy.  the trubble was getting the head off.  but the t-belt sould be nothing.  lata stu

The 8 Valve and 16 Valve SOHC motors are basically identical except for the valve train.  Changing the belt is relatively easy if you have a set of sockets and some patience.  Here's the basic procedure.  This is not by any means exact, but it will give you an idea.

1.  Disconnect battery
2. Set motor at TDC
3. Remove water pump belt and p/s belt (if applicable)
4. Remove fan, water pump pulley and fan shroud.  Usually easiest to pull shroud out at the same time as the fan.
5.  Remove the four outer crankshaft pulley bolts, and remove the crankshaft pulley.  You do not need to remove the center bolt in the crankshaft.
6.  Remove timing belt cover
7.  Loosen tensioner and remove old belt.

To install the belt, you do basically the reverse, but you need to remember to keep the crankshaft and camshaft properly oriented to each other(there are alignment marks).  Get yourself a Haynes manual ($20CDN or so) or something similar with the exact procedures.

It's relatively easy to do and can be done in a couple hours if you're mechanically inclined.

OK thanks,

Sounds pretty easy, I'll do it myself. I've read somewhere that it's a good idea to replace the tensioner is this true ?

Hey there, I got my timing belt replace at 172,000 kms, believe it or not...and my trust worthy mechanic said that it could have gone another 30,000 clicks...

My engine is the '91 8v.  I was not going to do it myself because I don't have the right tools or know how.  I bought a new timing belt and fan belt and had my mechanic install them.  He totally removed the radiator and fan to have more space to work with.  I only paid $190 CDN for the job, which is pretty good because Canadian Tire said it could cost as much as $450 CDN.  Nuts to that!

BTW: I am aware NOW that timing belts are not to be taken lightly and should be replaced at least every 100,000 kms.

According to the FSM you need to slacken off all the valve lash adjusters (?US terminology) when you replace the belt to ensure that the tensioner adjusts properly.

2. Set motor at TDC




This is TDC on the compression stroke right??

yes tdc on no#4 not no#1 but no#4 got it 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4 4
ok i think i have properly ilisrated  the fact that cam timeing is done on cyl no#4 at tdc...........

if you try to time it on no#1 the disty will be 180% off and you will be scrathing your now hairless head trying too figure out what went wrong........... :o

I usualy put on a new water pump while I'm in there since you got to move the belt to change the pump anyway. In the FSM it says that you should loosen the valve adjusters for proper tension. But I have never doon that in the years I've been changing timing belts and I've never had a problem.
