Timing belt change

[Chihua33]

I know there are a bunch of threads about this, but my question is.

I found someone to change a gasket thats leaking and he said that he would have to take the timing belt off so I should get a new one for when he replaces it. Now he said that I should get the belt and tensioner and idler pulley?

I see on autoricambi they have a kit with the belt pulley and water pump....is this the kit that I should get?

The guy I talked to said they usually come in a kit and this is all I can find?

Thanks for any help ahead of time! Can't wait to get her all fixed up!

no reason to replace the water pump unless it's leaking. You may/may not need the tensioner bearing, but it's best to replace it if it has any noise. Is your mechanic going to check the head for flatness before he replaces the gasket?

[Chihua33]

He said it looks to be leaking from the cam housing. Would he need to check that for flatness? How do they get unflat? Also I wired my fan to a switch and it works but it seems like it isn't cooling it down? Could I have the wires switched and the fan is spinning the wrong way? That may be a stupid question but I really don't knOw

The black wire to the fan is ground, the green one is power. But reversing them won't make the fan run backwards, it would probably fry the motor.
With all due respect to you Mark, when I took my training course from Ace in timing belt replacement we spun the tensioner bearing and it was smooth and free, but when we were moving it around during the belt install it fell apart. So I'm of the school that believes if you don't know when it was changed, change it now.
As far as the water pump goes, if there's no slop in the shaft and it spins smoothly without any gritty sounds, it's probably OK.
For the newer members of the forum, my training course on timing belt changing. (Ace is at the car)

Well then my fan is running right but doesn't seem to cool very well? Maybe I didn't leave it long enough.
As for the belt then would I be better off buying that kit for 80 bucks or whatever it is? That has everything I need plus the water pump just in case?

He didn't provide you with proper refreshments during the class?!?!
Heathen!
And no fender cover?? Ummmmmmm, I'm telliiinnnnnnn.

Funny you should say that Roy. Here's the same picture after Fiats2000 (Eladio) photoshopped it;

PS When the photo-op ended and the work started we did use Ace's "FIAT" fender cover!

The radiator may be partially plugged, or the thermostat may not be opening all the way.
It just needs to be diagnosed.

If you are paying someone else to do the work it may be better to change it now, as it is very little extra labor to change it, and if it goes out in 1-2 years you will have to pay someone to undo the cooling system again.

If you want to do it as cheaply as possible then leave the water pump alone (as long as it turns smoothly with no play) and get just the timing belt and tensioner.

with all due respect Ron, if your bearing was so bad that it would just fall apart then it needed replacing. If a bearing could just fall apart without having already failed, what would prevent a new bearing from "just falling apart"?
Cooling fans can run backwards if wired backwards. If your fan is drawing air through the radiator, but the temp doesn't drop you probably have a plugged radiator. Test each cooling tube with an infrared thermometer to find the restricted ones

Mark,

Say you're looking at the fan from the drivers seat, which way should the blades be turning?

[RoyBatty]

Easy way to tell.
With the fan running. CAREFULLY lower your hand between the fan and the engine. CAREFULLY.
Now then. was the fan pulling air towards the engine? If so, it's going the right way.

[rlux4]

Oops, you're right Mark. I guess I forgot that the motor is DC.
