Write off....no way !!!

[Mazza]

Thank you @Mor61e , for the info regarding the foam liner. Now I know its sound deadening I have ordered some 15mm grey air filter foam and will make a replacement liner. ( Blue Peter Badge time !!)

Just been reading a thread from @alec.m regarding the water pump......which has had me thinking, which is always a worry !!!
I have no idea when mine was fitted, and it doesnt look that new, so, as I havent put the antifreeze back in yet just wondering whether to replace it.
Like @alec.m , not sure which make to go for, but they only seem to be about £25.00 - 30.00 for my car so I suppose its a bit of a no brainer.
One thing I did come across, from RealOem, the part number is 11510393338, and using this I found various parts on the internet, but when I used the ‘check compatability’ feature on one of the advertised units, it said ‘does not fit your car’

Any thoughts on SKF, Meyle, Vaico, Valeo ?????? Or or better make?

Changed my water pump and bits a couple of months ago and used Meyle , bought from ebay for £26 came with 2 year warranty and it had the metal impeller instead of a plastic one , only time will tell about reliability but seems a solid unit

 

[Mazza]

Thank you @Bampz , I think Meyle gets the nod. I have just seen on another thread that @mrscalex and @Mario have also both used Meyle pumps.
Just ordered one from ebay (bmwmotormec) for £24.98 with free delivery.

I’ll start tomorrow getting the old one out, so its all cleaned and ready for when the new one arrives.

If it's stuck to the block when you've removed all the bolts Malc there are 2 threaded holes into which you can screw bolts to force it off just in case you didn't know.

Is that the same for the 6 pot pal, had a game with mine and ended up using a slide hammer

I changed my water pump earlier this year and had heck of a job getting the old one off. There is a thread about it on here someplace.
Also used the Meyle pump, metal impeller, seemed OEM quality, no subsequent problems.

Yes Sean same for 6 pot , I was at the garage when they were changing mine on my 2.8 the mechanic called me over saying he was struggling to remove old pump ,told him about the two threaded holes to help remove the pump two minutes later pump off , mechanic asked why I hadn't mentioned this before as he was struggling told him he wears the overalls . Good job I know him

 

[t-tony]

I didn't know there was till the day we did @Grumps water pump etc.

Tony.

 

[Mazza]

Just looked at the Bentley manual.....and it does mention the M6 threaded holes for removal of the pump for both the 4 and 6 pot engines. ( but not the S54 engine)

The foam liner inside my air box was also disintegrating to dust, I took it all out and didn’t replace it. Hasn’t made any difference at all, and doesn’t sound any louder.

 

[mrscalex]

Don’t use any old bolts to remove the water pump. I used cheapo non-graded ones on an M44. I’d put a new pump in and then decided to break the car instead. So I tried to retrieve the pump for reuse. Bolts both sheared off presumably because the seals on the new pump were so tight being new.

 

[t-tony]

Did you grease the seal before fitting them?

Tony.

 

[mrscalex]

Did you grease the seal before fitting them?

Tony.

I think I usually smear a bit of antifreeze on the seal. It’s never a problem going in anyway.

 

[Sean d]

Tony.

I had to put a smear of oil on mine as it was bloody tight getting it in pal

Check with the supplier that the impeller is metal before you buy. A couple of years ago, when I bought my Meyle pump there was some information around that they may be changing to plastic. Not sure if they ever did change to plastic, but best to check.
Whilst you are changing the pump have you considered changing the thermostat, sepentine belts? It would be worth checking the tensioners as well.

The picture in the advert showed it to have a metal impeller......
The thermostat and belt have been changed, but although the tensioner seems ok, may be worth getting one anyway while its all accessible. Something else to sort today.

 

[mrscalex]

I had a Meyle bought in last 12 months with metal impeller.

I had an Alhambra that was overheating. It initially confused the garage as everything looked okay. Then they discovered the plastic impeller spinning on the shaft where it had come loose. But was otherwise looking like it was okay

 

[Mazza]

Ok....success and confusion in equal amounts today.....

Removed the fan, and plastic from the front of the engine. Getting really good at this now and quick !!!!
Removed the 4 screws holding the pulley, removed the fan belt and then prised off the pulley.
Removed the 4 hex drive screws (3off 5mm and 1 off 6mm ) holding the waterpump, and used ( as advised) new 6mm bolts to ease the pump out. All good and the pump came out without any problems. Except even though I put a bucket under the engine managed to dump a load of water on the floor .
Then 15mm socket to remove the tensioner. (NOTE this is also reverse threaded like the fan)
The pump was not bad in its condition but there was a bit of play in the bearing, as there was in the tensioner.
Bit of a clean up and ready for the refit.

Securing bolts removed
The 6mm threaded hole located between the 8mm fixing holes. One at the top and one at the bottom

Oops missed !!

Cleaned with a toothbrush and parrafin.

You can see the small lugs where the 6mm extraction bolts push on


All good to this point then the confusion started......
The tensioner doesnt appear to be the correct one for the bolt and lug where it locates.

The lug on the spring unit is about 12mm but the dia on the tensioner bearing is about 13mm, and the bolt is 8 mm dia. Is this meant to be like this?????

It suggests that the bearing is not the right one for the car, ( it is an INA, but cant read the number)
If anyone has fitted one on an M44 engine, can you let me know the part you used as need to get a replacement part now as no point refitting the old one.

The pulley you have is from the hydraulic tensioner. I couldn't find a replacement pulley for the spring tensioner you have so I replaced mine with the hydraulic one when I did ours a few years ago. I have seen complete spring tensioners for sale ( can't remember where at the mo)

Here's pic of 2 tensioners side by side. hydraulic on the left. It has different fixing holes but the holes are there on the block.

 

[Mazza]

@Brian4
Absolutely correct. Just been out to check and the tensioner on the car is the one on the right. But the pulley is the one on the left.

At some point during its installation someone must have said .....oh that’ll do !!!!! Grrrrrr!

I have found a Febi Bilstein one for £17.85 and after confirming that is the correct part for my car, ordered it. Should be delivered Mon/Tues.
