Bought a 2.5 SOHC to replace a 2.5 DOHC in a '99 OBW. I do not know the year, or the donor vehicle. I do know that it has 61k kms marked on it and cost me $300.

 

It has what appears to be an oil cooler between the block and the oil filter. The water goes from the port normally used for a block heater to the rump roast'y, then towards the water pump. The pump is damaged so I do not know if it returned to the thermo bonnet or to another return hose, or to the pump itself.

 

My question is; Is this factory for some other or future model? Worth keeping? and if so what should I order a water pump for? I know, more than 1 question. Anyway, thanks in advance for your thoughts.

I've seen these on Foresters. Don't know if they are really needed.

 

GREAT PRICE on the engine. Hope its a good one.

 

Doing HG's while it's out?

The water pump is damaged? On the new engine? As dave mentioned personally I would buy an entire engine gasket set from Subaru and reseal the entire engine and replace the t-belt and componants while its out of the car...

This is factory, and it isnt as much a cooler as a tempp stabalizer. It also helps the oil warm up in winter, as the water heats up faster then the oil does.

 

Damaged water pump?

The motor was from a crunch, bought off the floor. I am only using the block, putting the DOHC heads on it. I just thought that if this was a plus, I wouldn't chuck it. I already bought the new WP for a '99 OBW, but no place for the extra hose to go. Thx for the info. Jim

The water pump you got has the nozzle for the bypass return though doesn't it? I believe that's how that oil cooler plumbs in, one line goes from the heater core and throttle bypass return and the other goes to the little nozzle on the water pump, replacign that short length of hose that is normally there?

The heater hose goes in the right side looking from the front, and the hose for the cooler looks as if it should go into the left side. I would have to know the model and year of the donor vehicle to get the proper WP.

Like this one?

Precisely. Thank you. Will try to find a thermo bonnet with the hose nipple. Thx again. Jim.

Ohhhh interesting. That plumbs in completely differently from what I was thinking.
