Engine Temp/Damage Query.

[CraigW]

Well on my way home from work my power-steering pump pulley wheel decided it didnt want to be attached to the pump anymore and it has sheared the spindle bit in the inside . Have had a dry bearing for a while so I think the bearing has siezed.

I have another pump already (thanks athers ) so that is all sorted.

The pulley came off roughly 5 miles from home, so I managed to nurse the car home. But the belt went with the wheel and well the belt drives the water pump and alternator aswell. So I had to drive 5 miles with no water pump and very heavy steering.

But in the 5 miles the temp gauge never moved from the middle, will there be any engine damage that could of occured or should everything be fine?

Erm, I thought the water pump was driven by the cam belt?

In any case, if the temperature didn't budge then your engine will be fine. you'll probably need to charge your battery though.

Hmmmm . I wonder if it is,

Im sure on the 1.4 APQ engine its driven by the auxillary belt.

 

[M1KEH]

If it is driven by the same belt, which im not sure about on the 1.4. You probably got away with it cause it is so cold outside at the moment.

must admit i thought the AEX+APQ water pump was cambelt driven

drive belt = crank / alt / tensioner / pas

Dont think so as I am sure that my cambelt is covered.

The belt ive lost goes from back to front down the bottom of the engine.

 

[Fl@pper]

you got another pump you say ?

pic ??

 

[CraigW]

How does the oil pump run on the 1.4??

Looking at vagcat it looks like the waterpump is driven by the cambelt.

Water-pump is number 11 on that diagram.

Im now wondering what the big wheel at the back on the outside of the cambelt cover will be now.

 

[Fl@pper]

crank pulley at a guess

I dont like the sound of that

 

[Fl@pper]

if it's just sheared off the pas pump and lost the belt then it's likely done nothing else apart from make ya arms sore and flatten ya battery a bit

Its sheared the power steering pump pulley wheel off and in turn has lost the belt.

When it happened the battery light came on, which i expected and that was it.

So there should be no internal damage or anything?? or starved of oil running the few miles back??

Yep it did make my arms sore aswell.

 

[M1KEH]

Nope from the diagrams on vagcat it seems the only things driven by that belt on your car are the power steering pump and the alternator so no other problems there.

 

[Fl@pper]

cambelt + water pump + oil pump all internal so shouldnt have any worries

 

[CraigW]

So the big pully at they back will just be like a guide pulley for the belt to go over and around??

And the camshaft and waterpump are driven by the cambelt?

What about the oil pump on these cars?

 

[M1KEH]

Oil pump will be driven internally by the crank somewhere. The big pulley at the back is the crank pulley which drives the alternator and power steering pump.

You should have one belt/chain that is covered, this is a toothed belt that uses the crankshaft pulley to drive the camshaft(s), water pump and oil pump. It is very important that this doesn't break, or even slip.

The one that (usually) isn't covered is a ribbed belt that powers all the extra parts of the engine that aren't 'critical'. So that's the alternator, power steering, aircon, and again they're powered from a crankshaft pulley. This can slip, break, get removed etc, and the only thing that will be a problem is the ones you had.

It's unlikely you will have damaged the crankshaft pulley, at worst the securing pin breaks and the pulley falls off but it doesn't sound like that's happened. All you've got to do is replace the pump and then put a new belt on. Check you get the right one though, depending on what you have on the car will depend on how long the belt is. It also does go round various pulleys and tensioners to get to the various parts, if that's what is confusing things?

That belt is alright, that is still in one piece. So thats alright.

Thats alright then, Im not going to have any engine issues then, which is a bonus .

I only had a quick look in the dark with a torch but I think that the pulley wheel is still there, just minus the belt.

I did notice that belt goes around a fair few pulleys and tensioners and things.

 

[CraigW]

Sorry to dig up an old thread but Im after some help.

Had a look at the car over the weekend and it is as suspected, the shaft that the pulley wheel has broken/sheered and the whole pulley is gone.

But can anyone explain how my battery and that area were covered in power-steering fluid when the pump is on the other side of the car?

 

[Fl@pper]

the underneath of the bonnet itself will give the best clue but pretty much the same way as stabbing a hole in a shaken up can of coke and firing it under there would cover it all too

either that or a sudden stop of the pump drive backing up an overflow of fluid to the pipe/reservoir which is next to the battery ?
