Hi. I'm a Very Newbie. Have never worked on a Subaru B4. This one belongs to a friend. Now I'm stuck.
We have to remove the water pump to replace it. So far Radiator is out (folded back over engine still on most of its wiring) and also the AC "radiator" still on its pipes but hanging down out the way. Only 2 water pump bolts visible, both removed, the rest concealed under the timing cover. Looks like the crankshaft pulley needs to come off to allow removal of the timing cover to allow access to the lower bolts holding the pump to the block. Do we also have to remove the AC compressor and alternater so that when all the bolts are out the water pump it can be withdrawn? Looks like there is a metal pipe from the pump to the the bottom hose. Is that part of the pump? Does anyone out there have some short cuts or tips please? eg- How does one remove the crankshaft pulley? Is it left hand or right hand thread? Will we need a puller? Did the engineers think the water pump would last for ever or did the do this for a joke on blokes in sheds?
Ho hum - it sounded like a straightforward job when I spoke to someone who had recently done it. Can only assume it was a different (and easier to work on) model......

G'day mate - yes the old L series are a bit of fun.

Basically you need to remove the AC, alternator, crank pulley, timing belt (pass side only needed to be removed). The AC and alternator can be removed as an assembly and swung over to where the battery resides. This will allow maximum access to the cam belt and water pump.

The pipe you've asked about is a heater core pipe - there's a rubber hose that connects this to the water pump - its best to replace this hose while you're at it and make sure you do up the clamps

Once you've removed all the cam gear you'll beable to access the water pump for the swap. Then its the reverse of what you did to get to the water pump. Just ask if you need instructions for the cam belt timing.

Good luck, it can be a learning curve but once you know these things they become easy (we just swapped a gearbox in an '03 corolla, that was a bit of fun).

Thanks for that Bennie. Just wot I needed.......the cam gear too! Lordy, just too much fun! There is a very good chance we'll be calling on you to talk us through a few "details". Thanks and best wishes to you.
