Does anybody knows were the oil cooler tubes are fitted on the engine ? I've got an oil radiator from a Delta HF, and I was wondering if it's easy to transormed as an oil cooler for my Fulvia 13 II s.
Any photo available I'll be welcome.
Thanks

The hosed are fitted to the oilfilterhousing. This is of a different design for oilcoolerfitted Fulvias. Housings are fitted to S1 cars with the S in the type name like coupe 1.3S, Sport 1.3S and HF1.3 and 1.6 First series only. There is discussion on the need for an oilcooler on a Fulvia but I think it is a good investment. The oil in my mildly tuned1200HF reaches over 120deg C during track use so I would fit an oilcooler if this would not sacrifice the orginality of my HF. Modern oils have no problems with 120 deg C anyway.

Yes, the oil coller take-off was quite a nice design and incorporated a thermostat set at rather a low temperature for the oils of today. It is marked 818342 showing that it was originally developed for the 1.3HF.

Of course for your car you can buy a sandwich plate - e.g. Mocal supplied by Think Automotive. AT the smae time you might consider ditching the bulky and heavy Fulvia oil filter. Just cut off the tube making sure there are no metal filings anywhere, and use a filter with a one way valve. I use Integrale/Evo or Thema turbo ones. I took the view that what is good enough for a 200+ HP turbo-charged 2-litre was good enough for my Fulvia!

The Lancia Delta oil cooler has quite the same size with the original 1,3 HF cooler. Its aluminium ofcourse.
Here in Greece during the summer the outside temp reaches thn 40* very often so, even with the modern oils (I'm using 10-40 ESSO semi synthetic) for sure the cooler its a good investment. Consider what happens during track races.

Woudln't an oil cooler make the engine take very long to heat up to working temps? Or doesn't the oil have that big an effect on engine temps?

My car allready takes too long to heat up to working heat (might be the thermostat)

Here in South africa it easily gets to 40C in my hometown 46C to 50C is normal for summer.
Even in winter i rarely drive in temps below 20 to 25C.

Will the oil cooler help that much for engine temp?

My car only comes close to the 200mark in BAD stop go traffic. And then the electrical fan really does a GREAT job. Although i had a radiator leak and when i took it in they changed my fan swith for a low temperature one which now comes on too soon and makes my car a bit noisy with the fan running too much.

The fan switch should operate at 90-95 C and off again at 85-89 C.

Could the oil be much warmer that water temps?

If you install an oil cooler, you should also install an oil thermostat. If so, it should not inlfuence the time to heat up.

No, there is alays a thermostat in the oil circuit.

Cold oil is very bad for engines!

i'd rather keep my s3 lancia without the oil cooler then, i hardly rev it high for prolong periods.

If i drive on the open road at higher rpms the wind blowing underneath over the sump must be enough to cool the oil down. This will propably not be the case for rally used cars.
