A couple aftermarket oil coolers.

The Coolex one has been available on eBay for years and I certainly would not term the company as cool experts by any means - sorry Andre

However - in my opinion - it is not suitable for the 14. I did purchase one for my 14 but sent it back immediately as the flange going across the top, whilst stronger, also stops any sort of air flow getting to the fan, should it operate - and whilst there are those who claim their's never comes on, mine did a few times on very hot days when standing still in heavy traffic. Had it had the coolex oil cooler on, then it would not have been able to operate and cool the oil.

So for me - if I still had my 14 - I would not bother with the Coolex rad (and this was discussed with them a few times on the old org, as a previous orgster used to work there).

A far better option - if you want the standard oil cooler - is the replacement option from Aaron Radiators (they don't sell on eBay) who completely rebuild the standard oil cooler removing the known weak spots (i.e. the hose spigots) by welding those on properly whilst maintaining the standard flange across the top with appropriate space for the fan - should it need to operate.

From my experience, those who have used Aaron, have in general found it to be a quality product.

No need to be sorry Dave. Just like to have options if the need/want arises. Thanks for sharing your view and the info about the previous orgster who worked there. Would be interesting to know their rationale, if there even is one, for not changing the flange. Seems to me that it would be easy to modify.

I did notice the flange. And I noticed a similar flange on other coolers as well. The hel cooler pops up first in my mind. Wouldn't it have the same issue? Haven't heard it being a problem, which doesn't mean there is none.

I am aware of the Aaron. Looks good and is to be had for a decent price and they offer to get you something more efficient if desired.

With the second cooler (race) from Coolex you could ditch the fan altogether if it is as efficient as advertised. Same goes for a more efficient Aaron.

However, for street use in Europe the original and the Aaron (if as efficient as the original) are plenty efficient. For much of the year even too efficient imo! Which can be helped with a thermostat.

Never had trouble with cooler so know nothing. If the weak spots have been noted, would it be a good idea, preventative maintenance, to get mine out and strip n rebuild? What exactly is the problem that happens?

[gsxbarmy]

In short Grog - no - as standard ones can't easily be fixed.

The issue is the joint around the spigot that each of the two oil pipes fit onto. Essentially it's a weak joint and is often where leaks come from. So I understand, if the joint goes causing a leak then it can't be fixed by braising, welding etc - why I don't know but essentially if it happens it's a case of replacing the cooler. I suspect it can't be fixed as there is insufficient metal around it to enable same.

The aftermarket Coolex and Aaron's have the joint around the spigot beefed up in construction such that it isn't an issue.

First a clarification (or correction). When Dave and I mentioned the flanges we both (I for sure) meant the mounting bracket. Was a little late when we wrote these posts.

Never had trouble with cooler so know nothing. If the weak spots have been noted, would it be a good idea, preventative maintenance, to get mine out and strip n rebuild? What exactly is the problem that happens?

Never had the problem either. But others have had it (sometimes twice), regardless of miles.

Apparently the location (EDIT: most often affected) is the lower left flange area of the cooler that gives.

The flanges on the original are vacuum brazed. Besides other advantages, main advantage is no need for secondary finishing (money in the bank for the manufacturer), it has as main disadvantage a lack of joint strength.

It's not a given that the flange will leak but the risk is there and it is not negligible given the number of instances I heard of. You got the money and don't want to have a slippery experience? Upgrade to something more robust (welded) imo.
