My PAS lines have sprung a leak, thankfully only the return line, but the supply line doesnt look far behind, its extremely rusty. I've ordered a good used set off ebay as it appears getting new ones is near impossible now (especially for the supply line).
Is there any useful tips or tricks for fitting these? Am i going to have to pull out the fan and rad shroud? Or is it possible to get them out without?
V8 I take it? i've done the supply line in the past, I removed the shroud and fan... Make life easy for yourself :)
Tackled this on sunday.
I couldnt get the fan off (hate those damn things, i wish they would provide a decent locking mechanism!) which no doubt made it harder, but the main issue was actually the engine oil cooler hard line. The pipe couldnt move over to clear the box due to that line, and it couldnt move forwards due to the gearbox oil cooler line. I couldnt undo the gearbox cooler line as the whole rad frame was just moving around, it seems to be rubber mounted, and the thread in the gearbox cooler was proper stuck.
Once the engine oil cooler line was out the way, i managed to wiggle the pipes thru the tiny gap. Annoyingly i spent half an hour carefully painting up the new pipes to hopefully help them last a bit longer, and scraped them all up shoving them back thru the tiny gap.
Not a pleasant job, mainly because of oil pouring everywhere, and the whole underside of the car being covered in oil too. I think the gearbox oil cooler is also leaking, and no doubt the engine is too. Everything between the radiator and gearbox is just absolutely covered in oil.
To get the fan off, I use a real (IIRC 36mm) wrench and tap (hit) it with a hammer. The thin walled wrenches they sell as fan wrenches are too flimsy to break the fan attach nut free. Once it’s broken free the fan wrench works great.
I use one of the thin spanners but have a lump of 1" steel bar with a hole drilled in the end. Put that over one of the pulley bolt heads and belt the spanner with a hammer. It comes undone 9 times out of 10 (for the 10th leave it in place and struggle as you did).
yeah last few times i've used my big shifter spanner and just whacked it with a hammer.
This time i was probably not helped by the belt being covered in PAS fluid so it was probably slipping more than usual... I also couldnt remember what way i'm supposed to hit the thing, tried both ways. And with nothing to counterhold it was just not budging.
I once had new PAS lines for a Merc ML made up by Pirtek, it cost much less than buying new lines from Ebay or a Merc dealer and I had them make the lines a couple of inches longer than the broken originals to make routing and re-connecting a bit easier.

To undo is anti clockwise on the petrol, clockwise on the diesel.
