Words, no pictures.......

Guys

I can describe what Mal is talking about. When I did the oil change on my wife's SVX I noticed the sandwich plate Mal is refering to, and I've seen them on other European cars. Think of a small heat exhanger fitted between the oil filter housing on the engine and the oil filter itself, normally it fits on the thread the oil filter would normally "spin" onto, and have a mounting thread for the oil filter to fit onto it rather than the engine, if that makes sense.

This device also has two coolant pipes and is spliced into the water coolant circuit. When the engine is cold, the oil will heat up faster than the water, so heat will transfer from the oil to the water to improve engine warm-up. When the engine is hot the water will still be cooler than the oil, so the water will help keep the oil temp consistant.

Make any sense to everyone ??

Significant Technical Input
Such adaptors normally have a bi-metal spring inside that blocks water flow when cold to allow the oil to heat up properly.

Some automatic transmission Forester and Legacy models with the EJ25# have the same type of heat exchanger between the block and the oil filter. All of the parts are readily available from Subaru.

We know one hose from the oil cooler goes to the "Extra European Nipple" on the water pump, where does the other one go?? hmmmm... this may be a good mod for the racecar??

I meant why is there no device like this on the SVX

Maybe due to the possibility of extended higher-speed touring in Europe than the states? Or maybe.... do European versions have a trailer hitch option available?

Probably figured there was more sustained high-speed traveling in Europe then in North America. Or congestion. Or maybe Europeans demand oil coolers in premium cars.

The system is very simple though, and you could order all of the parts quite easily (not too expensive either) to retrofit it to your SVX if anyone feels the need.

My guess is expense.

In the US, the SVX back in '92 was a "volume" model. To you guys it probably sold in relatively small numbers. However the sales were significant to Fuji, and were many multiples of UK and European sales.

In the UK models, the car was priced at around £40,000, similar to a Porsche 911. So they could afford to add in technical extravagances. At today's rates this would be a purchase price of about $72,000.

I'm willing to bet that you guys could buy the car for probably half the above amount.

THAT is why there are a number of features the SVX did not get in the US, such as heated seats and motorised closing mirrors. Why would they put on all this stuff as standard, and then sell the car in the US for buttons?

The car was specced down to reflect the market price it would make in the US.

That's why, is my guess.

Joe

There's a nice picture of the oil cooler in Mal's other thread. I don't remember seeing anything like that when changing the oil on our JDM SVXes. Must be a Europe only thing.

Is there any difference in Subaru's recommendation for what oil to use and how often to change it between UK and US models?

Going WAY BACK for this one. No one ever answered Dave and I would like to know as well.

But it may be a waste of time as I can't find a supplier for the European version of the water pump anywhere. Still, it seems like it would be a nice "mod" for US spec cars. Faster warm up means better gas mileage and cooler oil at operating conditions means longer oil life and better high RPM lubrication.

My local Subaru quoted me a price for the pump, at least. Which of course tempts me to go the same route as Mal.
