GTA oil cooler

Hey guys,

My oil cooler has a slow leak (very slow) from the pipes at the bottom of the cooler and I'm thinking about swapping the cooler and pipe assembly when I do the next oil change.

I have found this thread:
https://www.alfaowner.com/Forum/alfa-...a-gt-jtdm.html

The guy on ebay is selling a 99 pound oil cooler and pipes. I notice operation alfa comments it will fit the GTA - will it do so without any modification to the rack that holds it?

I was looking at a mocul one but this is some 160 pounds cheaper and may require less modification - i think?!

Current Alfa: 2003 156 2.5 V6 SW
Previous Alfas: SudSprint 1.7, 156 2.0ts , GT 1.9 JTD, 156 GTA, 156 2.0JTS Sele

couple of issues..

that one is out of stock on ebay

mounting shouldn,t be much of an issue i,ve just bought a 19 row to go on but havent fitted yet but they mount of rubber bobbins and cant see there but much of an issue.
pipes might be a bot different but pirtex can make pipes up easily if you have the old ones off

The stock isn't a massive issue as i'm not due an oil change for a while. I've got time to play with.

Where did you get your kit from?

Alternatively...

If your going to do it yourself have a look at Demon Tweeks they stock a heck of a lot of products, and really helpful if you actually go in.

And don't think that you have to go for Mocal, plenty of other companies out there that can supply a suitable rad, its a none moving part at the end of the day, as long as its made from a good grade of aluminium it will be fine

When it comes to the hoses either use the old pipes or get the correct lengths (use any kind of cheap hose as a mock up) first then go to the likes of pirtek, or google a hydraulics company. 9/10 you will have one locally but you may have to search a while.

Then take the rad and the original hoses to them and tell them what you want, easy as that.

thanks Sam, have you done your cooler?

I've been looking around and although the mocal one looks like the business I was hoping the product in the OP would be suitable at less than half the price.

Not on a GTA pal, from past experience on 4x4's. Used to use a custom company, but i cant remember the name now, ally...soemthing.

Think it depends on if its your daily driver, and if you can have it off the road. Just checked the price of the aeroquip fittings and its probably cheaper to use hydraulics specialist or try old school fittings and a jubilee clip, nothing wrong with them, again just use good quality clips. Find out how many rows and the width of the std cooler then just match it.

Check this out for the cooler, experiment with the different makes, but they are all good quality.

Oil Coolers & Accessories | Oil System | Motorsport | Home | Demon Tweeks

And here for the hoses:

Oil Hose & Fittings | Oil System | Motorsport | Home | Demon Tweeks

Upto you how much you spend on fittings, but dont go overboard, its not on show...

Just checked out the fittings on the oil pump side and it will be more complicated as it requries a fixing plate to clamp the pipes in place.

If it was me I would replace the cooler and cut the pipes to the cooler, you'll save cash and if the connections to the oil pump arent leaking them leave them alone, if its not broken dont fix it. Or fork out another 100 quid to fix something that isnt broken...

Sam.

another vote for autolussos kit. Was very easy to install and at a fair price consider the OEM prices.

Quick review on the AL Mocal Kit.

Its a bit big, but will fit snugly.

Oil Temps still goes up to 3 bars on daily driving, and spirited runs.

At the track, it goes up to 4 bars and stays there for the duration of the track day.

Am using 10W60 oil as a reference point.

Really? I use Valvoline 10w60 (thanks for the advice guys) also and i normally sit at 2 bars on the motorway at 70 and 3 bars on a normal drive, never seen 4 bars.

I was only going to replace the rad as the pipes need changing and it would seem a false economy just doing the pipes for the sake of a few extra quid. Also I'm trying to upgrade parts that are worn or break with better if the cost is negligible...

Maybe not worth changing the cooler then... possibly just do the pipes...

Just to be clear, I live in the tropics. Average temp here is about 26C on a cool rainy day to about 36 on a hot dry summer's day.

Track days are about 40C-45C or maybe more in the summer here.... which is just about all the time.

So just a ball park figure....

Sorry - yes i've just noticed your location!

Well I live in the north of England where it is freezing, snowy and grey. I guess if i just use the car in winter I could just by-pass the cooler altogether!

Hi there, consider checking that the actual connections (to the cooler and to the engine) are still in fact tight and may just need to be tightened up again properly. I know that oil pipes generally tend to "sweat" at the connections etc, hence the possible replacement of the old seals with copper/aluminum one's for example may also be a consideration on your part. Unless of course you have damaged the cooler/pipes in any way.

Hi - thanks for the advice. I havent yet touched the pipes. The bumper came off recently to allow for the respray and whilst i was off it allowed me to inspect the pipes. They are leaking at the cooler end, but are also pretty rusty...

I think its a replace job and i'll do the rad and possible the rad bracket as well....

here is a snap...

you think it looks bad??

Bad would be ****ing oil all over the garage.

Nah - this is a 'fix when i can be bothered' job.

Its a slow leak so unlikely to just 'let go' - or could it?

Yes it can let go, I can recall at least a few GTAs & plenty of GTV V6s coming in on the back of recovery trucks with burst oil cooler pipes. It doesn't always end well either. I would change them as soon as you can.

i had mine looking in that crusty condition and then at somepoint the oil cooler connections let go and sprayed oil all under the car and over alot of the area around that side. Lucky there was no fire but it made a mess.
I reckon it was the italian way to say i might be getting rusty and need some rustproofing lol
