Heres a hardline setup I made for a 912E... The customer wanted the stock front mount 911 oil cooler setup. Used a Mocal sandwich thermostat.

It's spam. Just to get the link in the sig indexed.

Hopefully the post and the spammer will both be gone soon.

Do any of these systems incorporate in- line check valves in the lines to or from the cooler ?
I just bought 76 that is fitted with ex cooler and has check valve in line, not sure why needed (or if needed).
Comments ?

I would guess that the installer wanted to keep the oil in the external cooler and piping from draining back into the crankcase, resulting in a high oil level in the engine.

I have wondered about that occurring if the cooler is higher than the normal crankcase oil level. Is that an issue or problem? (IMG:style_emoticons/default/idea.gif)

Instead of the sandwich adapters I have seen an adapter that replaces the OE oil cooler. I don't remember where I saw it though. Basically it was a plate that had AN fitting that bolted replacing the cooler

The cooler is presently mounted vertically to the underside of the rear trunk, so at about same level as sump. I just got car and it isn't running, but I'd like to reposition the cooler in the right rear fender well as I have air scoops into that area and it's then further from exhaust piping.

I'm glad for this thread. I want to install a second oil cooler on my LE, but because it's an LE, I don't want to chop it up. Any add-ons I do I am trying to do without performing surgery to its originality. So basically looking to just bolt on.

My other 914 has a second large oil cooler that is simply bolted to the floor pan underneath the car right before the engine bay opening. Being underneath the car it gets constant surrounding air, so there's no fan. This simple setup has worked fine for this car but I am not sure what the best placement would be for optimal functionality and protection.

Also, I'm not really sure what the best oil cooler to get would be. being in Florida I have very hot temperatures and drive my car year round. So I would like a larger cooler with optimal performance to help protect the duration of my engine and give me better performance. Also, if I need a fan a/o thermostat. I suppose living in Florida it's best to have the cooler operating whenever the car is on instead of just when it hits a certain temperature. Also I'm not familiar with this sandwich method that doesn't seem to be very popular.

From your expert opinions, what kind of oil cooler would you suggest I get? Where would you suggest I place it and how given my limitations of not chopping up my car? I did like the idea of it being turned at an angle underneath the trunk. Will this actually make it cooler by catching more air and having more oil in the cooler? And would it get enough air underneath the trunk? Also do I need a fan and thermostat? Any better suggestions than what I already have on my other 914 which is basically just a large cooler bolted underneath the floor pan forward from the rear wheels? Suggestions are much appreciated. Thanks!

I had one under the trunk floor in my 2.0 with carbs. Worked like a champ, but mine had a manual one/off switch for the fan. A cleaner install would be to use a thermostatic switch to have the fan come on automatically when the temp get to the set point. I just used a sandwich plate at the oil filter to run to/from the cooler. Bolted to the trunk floor with rubber spacers to get the spacing and isolate from vibration.
But, you could always make a bracket to bolt to the transmission mount to eliminate a couple of holes in the trunk.

I still have the cooler/fan/lines in my parts bin.

I'm doing something similar but with larger cooling capacity in my /6 conversion.

Re post #87: Nice installation, but be careful with that cloth braided line. Anywhere it rubs it will fray and then fail, especially if there is any pressure in the lines.

I have one I might be willing to part with almost identical to the pic with thermostat switch.
It would be minus the sandwich adapter plate as I am going to use that.

Is this the setup you are thinking of?

I have a batch of adapter plates for the cooler location sitting in a box here.
I also have some inline thermostats, and some block-off-plates for the tin.

I've been trying to find time to complete a kit which includes premade hoses between the adapter and the thermostat, with options for either a front or a rear mounted cooler.

That is a good idea ........ is tapping the oil cooler location better for the oil pressure, than the oil filter sandwich? Or is there no difference? ... (IMG:style_emoticons/default/popcorn[1].gif)

It eliminates the stock cooler.
The air normally supplied to the cooler becomes available for improved cooling of cyls 3 & 4.

I think its much better - for several reasons including improved oil pressure.
1) Added load on the filter circuit increases the likelihood that oil will bypass the filter unless the bypass valve is blocked.
2) A sandwich plate adds complexity (& drag) to the oil circuit - lowering the available pressure to the bearings.
3) The oil cooler inlet and outlet are already there on the block.
4) The stock filter mounted on a sandwich plate hangs down to where its hard to get past the engine crossbar.
5) More cooling air available for cyls 3&4
6) The stock cooler is inefficient in the stock location. Its adequate for stock engines but not so much for higher power rebuilds.
7) etc.
