Hi Thomas, I don't understand it either, but all I can say is the original plug I have removed from the crankcase to return the oil is M12 x 1.5 I have not made any changes to the size

I will give a 30% to the ''looks cool'' factor and the rest 70% to engine cooling in my case I think that in a stock engine it will be effective even if it is not located in the most sufficient place. During winter engine temp is just bellow to 80 Celsius, at summer around 100 or 110 in traffic and 115 at big hills. My goal is to keep it during summer at 90-95. If i don't manage it at first place i might use a scoop, a fan or a different location. Little car can keep you busy for a long time if you are looking for trouble.

Re: Oil cooler installation

My cooler is fitted under the car with a venturi duct to push air over the core when moving

Re: Oil cooler installation

Speaking of those oil coolers located under the car, is there any photos available to get the idea? Also can i use a transmission oil cooler? Many of the small available oil coolers that i am looking for are transmission coolers.

Re: Oil cooler installation

Tom "hobbler" gave me a link to a YouTube film showing the venturi and the cooler install.
I'm sure he can send you this info.
Transmission cooler is fine. Are you going to fit a filter or oil thermostat?

Re: Oil cooler installation

Well if Tom is reading this...
No I am not going to use a filter or thermostat. I think that fiat centrifugal filter is enough. You know those transmission coolers have smaller tubes and I am not sure if they going to limit oil circulation which in the other hand is low press in this engine. I like them because they are small in size.

Re: Oil cooler installation

Evening Tom; The u-tube series of films was entitled "Abarth 695--parts 1 to 8.
The film entitled '1.5' showed the engine build-up, and one of the later films showed the oil-cooler installation. The films, put out bu 'Dutch Abarth' sadly, seem to have disappeared. You might get something by seeing if 'Dutch Abarth' have anything on line. If I remember correctly the filter, a fairly shallow but wide filter, was fitted on the o/s of the car in the area just behind the rear bulkhead, angled a bit (top of filter further forward than the bottom of the filter) with a built-in air scoop to aim the cooling air through the filter.
With regard to fitting a gear-box cooler, being that there is no 'oil pressure' in the gearbox, I cannot see how one would get the oil to circulate through the filter.
Sorry I can't bee of more help

Tom hi and thank you, yes i have reed about those series of videos but never found them in you tube. As for the cooler I mean to connect a transmission oil cooler taken from a modern car (those are full of coolers bmw M5 has 8 of them!) and connect it to my engine as an engine oil cooler.

Re: Oil cooler installation

Thomas,
I bought an oil cooler from a 1988 GSX 750 bike. (I can take dimensions this evening.) There are a lot of bike oil coolers that are a good size, this was just a random gamble from ebay. Many bikes have non-standard pipes so check the fittings look normal.


I plan on fitting mine under the car roughly where the petrol tank sits in a 126 so it sounds like my set up will be similar to yours. I've added a photo of the modified timing chain cover. I don't think there are any modifications to the inside, but I can check against a standard one. I will also post a few photos of the CNC block that bolts on top. As I mentioned in the other post this is a loan but I intend to have the fitting braised on. O-rings are great, I prefer to avoid additional sealing points.


Michael

Re: Oil cooler installation

Michael hi, If you don't mind can you also take pictures of the inside of the pump to see the gear mod? I still don't get from where the oil passes if you block or restrict the gear hole down to 2mm I guess I will when I get mine in hand. Anyway post as much as you can if not a problem. As for the take out I am planing also to weld an output but I also might buy the adaptor. Your cooler is nice and I am looking for something similar.

Re: Oil cooler installation

I'll get another photo of new and old compared, it might make more sense. The M4 Capheads normally live on the outside to hold this adapter in place:

I just fitted them inside so I don't loose them. The oil cooler was very cheap. If you are looking for a low cost oil cooler I would suggest a motorcycle autojumble, it's a great way to hunt for a cooler by size rather than by bike.

Re: Oil cooler installation

Starting to make sence now thank you, is your pump gear also blocked? I have made a quick research and suzuki TL 1000 also suits my needs.

Re: Oil cooler installation

There was no pump with this kit which suggests it should be fitted with a standard pump.

Re: Oil cooler installation

From what I have reed so far, it is necessary to limit/block the long pump gear in order to force oil to get into the cooler.
