I checked the belt for condition, damage etc once it was off. It appeared fine so popped it inside the car for safe keeping.
Belt off so I undid the three bolts on the pulley and removed the pulley wheel.
The mess from the slow leak was now evident but also easy to see were the four fixing bolts and the one holding the mounting plate at the 12o/c position.
With good access, I undid the hp pipe fitting on the right hand mid point using a spanner from above and slid the locknut and pipe back a bit.
Again, lots of room for the socket and out came the two long, lower bolts and the two upper, short bolts.
Incidentally, I'm loath to use 12 point sockets on most bolts on the Landy unless I've no choice.
A good but expensive buy ages ago was a set of hex 'impact' sockets and they've paid for themselves several times with non rounded nut/bolt heads and they take a good 'knock' from a hammer on a bar too!
The pump now slides out, with, in my case the low pressure hose attached to the lp attachment pipe on the bottom of the pump.
I gave the open front of the water pump drive a wipe over and noted the alignment of the water pump drive.
I removed the LP pipe from the old pump and put it on to the new pump and tightened the jubilee clip.
I then took the mounting plate off the old pump and bolted in on to the new one using the single, central short bolt and offered it up to the engine.
I put the four fixing bolts back in (the two long at the bottom holes and the two short ones in the top ones) and tightened them up by hand.
I'd checked the alignment of the two pumps but still kept checking the rotation as it pulled in.
The four fixing bolts and the plate bolt were now tightened up.
There are torque settings but I don't have one so it was a case of tight but not over tightened. Refer to the manual.
With the pipe securely inplace,the HP pipe lock nut was now tightened up.
Next I refitted the pulley wheel. Fiddly but once the first small bolt is in, the other two go in a piece of wee wee. Again, these were tightened up hand tight then a light spanner pressure too, holding the wheel.
Hardest job for me was putting the serpentine belt back on. In the end, I got a length of rope and tied off the extension bar as far to the left as I could get it and finally got the belt over the main pulley the fan goes on to.
Another check over the belt to make sure it was properly in the grooves and the belt tensioner was eased off.
Fitting the fan is the reverse of the above and then underneath, laying on the rubber boot liner mat in the snow, to do up the jubilee clip on the LP pipe connection.
I wiped everything in sight down, top and bottom and the reservoir too then topped it up with the saved fluid, which was clean and a bit more from the bottle.
I started the car and span the wheel from lock to lock several times.
It made a noise at first but this disappeared as the fluid fed through.
I turned her off and left her for a while, checking underneath for any signs of a leak............nothing!
I didn't bleed the system but if the noise returns, I'll try it but right now it doesn't seem to need it.
Another point, the 'frothing' I'd noticed in the past in the reservoir didn't happen again, or nowhere near as badly so it must have been taking in air too and aerating the fluid.
So, finally, done and I'm pleased. It was a lot easier than I thought and I'd recommend anyone with a bit of common dog giving it a go if needed.
Bit long winded but I hope this proves useful to other numpties like me with limited knowledge and tools but driven by various needs, i.e. financial mainly!!
Cheers
