Timing belt change on 16v corrado 1990??

[sheppeydave 0]

Is it a straightforward job on a corrado to change the timing belt and tensioners can I buy a locking tool for the timing??if not what do I do???

[steveo29 0]

dont need a locking tool

 

yes straightforward enough with basic tool ..not a bad job at all

[sheppeydave 0]

So how do you lock the timing?

You don't, there's a timing mark on the cam pulley and an arrow on the cam cover, the crank pulley has a mark and the lower belt cover an arrow, intermediate pulley just does the oil pump so no need to time it unlike an 8v

Memory failing a wee bit her but basically. Remove timing belt covers. You will have to take off the ancillary belts and possibly one of the pulleys. water pump I think. Line up the spotty dots on the pulleys. Slacken off the tensioner. Remove timing belt. Replace timing belt and re-tension so that you can just twist it about 90 degrees. Check timing marks are still aligned. Rotate engine by hand a couple of times and recheck timing marks. Shove back all the other stuff and covers. Job done. Just a thought as I type this, the water pump pulley is retained by four allan bolts, undo these through he wheel arch before you do anything else. they are wee buggers to get off and the tension from the drive belt will keep the pulley from turning.

Had a further thought on this since I posted, I think the external drive pulleys all need to come off. Again these are Allan bolts and are best freed while the belts ae in place and tensioned. All should be obvious when you stick your head in there.

the lower pulleys are the biggest pain ...the allen head bolts are keen to round off given half the chance , so hammer the socket in with a sharp tap to make sure its seated

 

the crank pulley is just the 4 allen heads..not the 19mm in the center

Yeah, that catches people out, the water pump/alternator v belt drive pulley seizes to the crank timing belt pulley and makes it seem like you need to take the main crank pulley off, you don't :)

Hello do I just need to take the outer crank pulley off as I'm going to replace the drive belts as well was just going to slacken the alternator off then power steering pump and get them out of the way then can I get to the lower half of the plastic timing cover?

[steveo29 0]

take the big pulley off that looks like this

 

 

will leave it looking like this

 

[sheppeydave 0]

Yep done that but forgot to take the water pump pulley of now dohhhhhhhhhhhhhh:-(

Hello all stripped down now just going to take the belt off still have no idea where the timing marks are on the crank and camshaft there are white dots but how do you line them up and where do you line them up or is it just a case of undoing the tensioner and putting a new belt on hoping none of the pulleys move????please help?

[diarmaid16 1]

Do you have a new timing belt? The box should show how to line up the timing before removal.

[sheppeydave 0]

Nope doesn't say on the box it's a dayco kit???

[diarmaid16 1]

Here's a pic of the cam on mine. The tippex is just highlighting the groove on the cam pulley and it's lined up with an arrow directly behind it. Mines a 2 litre but yours is probably the same.

I've just manually turned the timing before removal and there is a white dot on the crank pulley and one on the cam pulley the cam pulley is lined up to the arrow on the cam cover and the crank is pointing down central do I not worry about the pulley in the middle?

[sheppeydave 0]

So now I have lined them up is it ok to losen the tensioner off and fit the new without the pulleys moving??

[diarmaid16 1]

Middle pulley is for oil pump so that doesnt matter. Should be ok now.

Yep, you might find the cams move a little under pressure from the valve springs when you slacken the tensioner, just make sure you turn it over a few times by hand to make sure it all lines up when the new belt and tensioner is on

[sheppeydave 0]

How do you get it tensioned up tight??

[sheppeydave 0]

Nope no idea now put belt on tensioned it up then went really tight:-( took the belt off turned the cam pulley with a socket and it went tight:-(

[sheppeydave 0]

Now it's ok but how do I re laugh the pulleys now especially the crank pulley???

[sheppeydave 0]

How do you tension the belt and how will I get it aligned up again now???

[sheppeydave 0]

The cam shaft also feels tight to turn over I'm sure I haven't done any damage by just turning it by hand but I think they were tight before ??

The belt is tensioned by rotating the tensioner in a clockwise direction. There are two holes in the face of the tensioner which are used to rotate it using a peg spanner. Some alternative suggestions here :- http://the-corrado.net/showthread.php?t=5169
