I had a bearing go out on an M30 WP. I watched the pump wobble around until it locked itself solid. Pretty cool to see it happen (true story).

Then I got in the car and drove home.

They all have that. It's a weep hole for when the seal/bearing fails. That's how you know your WP is bad.

Water Pump weeping

Post by gidgaf »

Umm, no,
This is in the flange- the part that bolts to the engine.
I'll find it, and post a picture.

Waay back in my olde Chebby days, if'n we found a leaky weep hole we'd sometimes stick a zerk fitting in there. Pumped full of grease, that pump would last at least a week or so. At least until you got to a weekend that didn't end in "rent".

I couldn't tell exactly which oil light the OP was speaking of......... could it have been the oil level warning?

Yes the oil level warning. Up by the rear view.
Got the WP out. It was crap. Althought the damn fan was locked up on it. Left it at the shop soaking the threads. Hopefully more luck getting it off tomorrow.
All of the belts look fine but I will be replacing them, except the timing.
Oh. The tensioner spring,I believe I know which way it goes but am not sure. Could someone post a picture?

You are aware that the fan is left hand thread. Just making sure.

Cool. They can definitely be frozen on the pump pretty good, but it sure makes it hard to remove if you are tightening it. Shocking the wrench with a hammer helps break it loose.

Probably worth it just to get a new clutch for your new WP at that point. Never tighten the fan with a wrench. I just spin it on until it stops. Also, use anti-seize.

Ahh your back. Funny or odd that light also came on during all of the rest of this adventure. I hope it is just the water pump that has gone bad and the additional driving didn't overheat anything. So maybe if the pump locked up the smoke was from belts not turning. If your oil looks good then maybe just a new pump and you'll be back on the road.

Have you removed the alternator/WP belt then started the motor briefly to see that the big crank hub/pulley is turning and turning the PS or AC. I really can't imagine any scenario where a key breaks and that thing comes loose.

I can say--the hammer trick works... I think I tensioned the belt a little tighter and that helped too....Probably took 15 swings of the hammer or so, then it just went.

When installed with my method listed above, I've never had to use more force than a bump with my hand to get the fan off.

Pretty sure you get the spring on before the belt goes on. Put the spring on, then the tensioner. Push on the tensioner with a screwdriver to compress the spring and then tighten the tensioner top bolt. That will hold everything in place so you can put the belt on. Then loosen the tensioner top bolt and the belt will be properly tensioned. Yes?

I'm not replacing the timing belt
I have a new one but the old one is still in good condition and I don't wanna fuck my timing up

$.02 - Don't be a bonehead. do the belt while u r in there. $25-30 dollars of insurance is cheap insurance.
You won't f-up the timing any more than you'll f-up the tensioning assembly. I have seen decent write-ups here or maybe at Rod Paine's site. You don't even need to buy a Bentley manual.

You can change the WP without messing with the timing whatsoever. But the spring falls out then you just put it back into the recess on the WP and align it with the tensioner as you place the WP. It's a bit more trouble fighting the spring but not so bad, I've done it before and would if the WP failed but I knew the t-belt was no where near due to be replaced.

Even more fail than before. Not changing the belt now is a great idea.

two bolts hold the tensioner in IIRC...and only one of those bolts deal with the adjustment--I think it's the outermost bolt?

Everything under the timing covers should be fairly clean and I'm confused as to why you're having such a hard time with it.

If you weren't planning to replace the timing belt you should not have messed with the tensioner at all.

The spring is only there for the initial tensioning of the belt during installation. After you get the belt on, turn the engine over twice and verify timing marks, the bolts for the tensioner pulley get tightened down and it doesn't move again.

My worked blocked the whole first page. Guess I miss out on the fun.

This thread is full of fail. Full of freakin' fail.

MrHill... put the tools down, walk away from the car slowly, and call a local mechanic.

You should really consider the timing belt to timing chain upgrade.
