Timing belt replacement list?

hands-on · Post by **hands-on** » Sat Jan 07, 2006 11:57 pm

now I got the pulley and covers off but there is just no way to get the power steering pump off enough to get the belt out.
do I need to lossen the engine mounts and if so do I need to loosen them all and if ths is the case shouldnt I just pull the engine for the valves and all the other stuff that is probably toast?

if it the power steering pump on the 1.6 then you have to remove the bolts on the pulley then remove the 2 bolts behind it and slide it forward as far as you can and carefully slip the belt behind it

its a pain in the ass but it will get the job done

did your belt break? is that why you think you have bent valves?

The belt was not completely broken but it had lost at least 10 teeth and the crank was turning without the cams.
but they all turn quite smoothly when turned by hand.
my plan was to put a new belt in and then check the compression to see if it is ok.
thanks for your repply

Hands-on....... I noticed your from Argentina... so I thought I'd ask which engine you have and which car is it installed in?

Some of the Daewoo engines are non-interfering..... so you can blow the timing belt and nothing will happen.

I'm from Argentina but I live in Lexington Kentucky.
the car I'm working on is a 2000 lanos with a 1.6 l engine and an automatic transmision. It also has power steering and AC, both a pain to work arround.
From what I have heard it has an inerference engine

Oh.... OK.... your posting from the USA.... I made the assumption based upon your flag...........the 1.6L DOHC is definitly an interference engine.... the 1.6L SOHC is not..... you can snap a belt and nothing happens.... you can have the car back up and running inside of a few hours.

The 1.6L SOHC is commonly used in slightly older vehicles.

most probably you bent your valves... losing 10 teeth is too much and since you can freely rotate the crank shaft then the valves are already bent so that the pistons now got clerance to move freely... or at least that is what i think.

indeed you have to remove the PWS bolts amd move it a bit to the front and slip the belt from behind it.

Just had my timing belt replaced. The items I got are the timing belt itself, idler pulley and tensioner but I did forget one item. The auxillaries belt which powers the A/C and all that. I got the water pump as extra measure and the mechanic replaced it because the old one isn't spinning as well.

What is not needed are the oils seals. He returned these to me. He is under the impression that oil seals are pretty OK items. Sometimes installing new ones might induce a leak.

Gasket golden rule: don't fix them unless they are broken.

Timing belt mechanism golden rule: fix them before they break.

It's one heck of a tight squeeze behind the power steering pump.
by the way I dont see any bolts on the belt tensioner that sits on the water pump, does it just pop out? are there any tricks to remove it?

i didn't really get what you are aming for so i will explain the two possible cenarios that can be best matched to your question:

1- you want to remove the gear on the water pump:

that gear is not removable, you got to remove the whole pump off the block.

to do that you got to remove the three little bolts on the block as illustraterd... ok their are 2 arrows only but the third bolt is not apparent in this pic because of the angle of the shot.

2- you want to tension/detension the timing belt:

you have to use the bolt shaped section of the pump to rotate the while pump assembly to tension/detension the belt, their is a special too to do that but a wrench of the correct size can do the job.

i had only 6 missing teath on the lanos im working on right now and it bent the 8 exhaust valves and maybe 4 intake valves .. although not sure about the intake valves yet..

chances are you bent some valves..

what i want to remove is the belt tensioner on the left, its not connected to the waterpump at all, my bad

DomWoo · Post by **DomWoo** » Sun Jan 08, 2006 11:32 pm

there is 2 bolts right next to the tensioner that hold it in. if you remove those it comes right off

the tensioner is now off but who was the sick engineer that put 3 allen bolts to secure the waterpump in a place where standard allen wrenches do not reach
