Well today the sun was shining and the air was warm ish and the ground was almost dry so I decided to crack on and get some jobs done. I'd read up on what was needed to change the aux belt tensioner and it sounded a right ****e of a job, so I'd been putting it off, but the screeching was getting quite embarrassing....
Well it's now done and the engine is lovely and quiet! The tensioner bearing was totally shagged- loads of play and dry as a nun's foo-foo. So, to get it off the undertray, side cover and belts come off, then the water pipe under the engine has to come off, the AC pump has to move, to get the AC bracket off, to get the alternator off, to get access to the 8mm locking nut on the back of the tensioner to remove the tensioner. Well, that's the theory. In practice the water pipe only has to have it's 3x8mm mounting bolts removed and it quite happily sits slightly out of the way so no need to drain the water. This is the same procedure to replace the alternator or AC pump so remember that... The pipe only has to move an inch or so to access the bolt holding the AC pump (3x10mm IIRC). The RAVE says to just swing it out the way. Which would be easy if it wasn't for the electrical wires on the opposite end of the AC pipes. I dropped it and rested it on the water pipe, the bumper lip and a bottle jack. Then the 3x10mm bolts are easy to get to to remove the AC support bracket. Once that's gone it's a 10mm bolt on the wire end of the alternator (you did disconnect the battery and remove the wires? Good..) just needs loosening, the 13mm lower bolt needs loosening, then the top 13mm bolt needs removing and the alternator swings down out of the way. Remove the bolt holding the dipstick pipe so that can move to allow better access. Believe me- you will need it..
And now for the fun part: getting the 8mm nut off the back of the tensioner pulley. I'd already removed the silver idler pulley (which I had replaced earlier as it too was shagged) which is a 5mm or so allen bolt. I used an 8mm ratchet spanner on the nut but it's quite hard to tell if it is loosening as you might get 1 click at a time on the ratchet so this takes forever and a day. I placed a magnet nearby so I wouldn't lose the nut if it fell off, which would be just my luck. I had to feed my right hand from the space behind the fans and around the dipstick to hold and move the spanner, while my left hand somehow turned and held the end of the ratchet bit on the nut. Painful to say the least, and I'm lucky I have gynaecologist's hands- long and slim. Sausage Fingers need not apply. So finally removed and then to remove the tensioner, it has to come out from the engine towards the wheel about 2cm to get it out of the tensioner slot then it can be spun 180degrees and pulled out. Except it can't as there's a chassis member right in the way. Basically, you have to lower the engine by an inch to clear it. Bugger. And it was all going so well.
By now the sun was getting low so it was time to get the lights out and hurry up! I put a jack under the sump and took the weight while removing the ait intake system to reveal the 4 14mm IIRC bolts holding the top of the engine to the engine mount on the drivers side (right). The jack was then lowered until the pulley could be removed. Hurrah! Finally out!!! Changed the seal (you'll see if you ever do it) then replaced the tensioner and jacked the engine up and refitted those engine mount bolts as quick as I could. Refitting everything was the reverse of removal as the Haynes Book of Lies likes to say, except for use of copper grease. Fired up and.......... silence!! Well, relatively speaking. SOOOOO much nicer!! :5bhurray:
As it was dark, I put things in the car and left it up on the ramps. Tomorrow I shall do it's oil change and then put the tray back on and cut the hole for the sump plug removal in the future. Can't believe I've done over 7k miles already....
Well, that's all the nasty jobs that needed doing when I bought it. Feel like celebrating now!! :lvbear-176: Think I'll go and see my great uncle and get blasted on his home made grog. We can celebrate his 87th birthday. :5bcheers2:
