Oil cooler

Hi guys and girls just a quick one. I fitted a updated modal oil cooler to my 1.8t mk1 a while ago and recently noticed people remove the standard water cooled oil cooler and just use the new one.

Is this reliable and safe to do. Is it just a matter of moving it and fitting the new sandwich plate for the new cooler. Hope this makes sense.

Cheers in advance and regards.

If you are talking about removing the Water Jacket cooler with the "spensive"  "T" hose and taking that straight to the Hard Line.  Then removing the Down hose and Plugging that.  Are you talking about adding an external air cooled oil cooler?

Or Replacing one style of water jacket cooler for another?

On my 90's Cabbies, VW over here at least did away with the water jacket oil coolers, The Jetta's, Passat's, Golfs still had them but not the Cabby's I am still talking digi controlled.  Why not the Cabby?

Since I noticed that my oil would get HOT (automatic) as compared to my Manual tranny in my 92, and 93 I chose to add an external air cooled oil cooler.

Being the Cheap Bastich that I are I opted to Scavage the yards for parts, and ended up with a Whalbro off a Volvo 240t intercooler.  It was a direct fit and required a
little modification on the interconnect pipe from my oil filter flange through the sandwich plate to the filter Original was too long and had to be shortened about an inch.  

I ran this to a Transmission (lower profile) exchanger in front of my a/c condenser.  

I have seen the water jacket one's leak oil into the a/f, and over pressurize the cooling system.  

I prefer to have oil leak to the floor, rather than the possibility of cross contamination.

In the archive section I have a how do I do that.

I don't think that swapping from one water jacketed one to another would be a problem save for the hoses.

On 90's that don't have it, I wouldn't add a water jacket one, I would go external air cooled.

The reason I went for the Volvo is that it was Thermostatically controlled to open full at 95C similar to a t-stat.

I went from about 145C oil on highway cruises with a/c to about 110-115.

my 2 pence.

Yes that's it and great reply. Yes I'm currently running a air cooled mocal oil cooler but also the original water cool one. With the information you've just given me I'm going to get rid off it and try just me air cooled mocal one.

How did you shorten the main pipe the one which the oil filter screws on?
Did you MOD it or is there models which use one.
Massive thanks for your reply 😁😁😁😁😁

I did it the old fashioned way.  Placed the cooler in place, and tightened the Volvo pipe in to my flange.
Ran a nut up to lock it in place Marked the Pipe with Paint.  Ran the nut off, took the old shorter one that was original and ran a lock nut up to the mark, rane another up to the guestimation, and lock nutted it,  I used a Sawzall to cut below the nuts… Using the nuts as a thread chaser I removed them to the cut area a tad low, locked them together and filed the edges, spun them off and wally it fit.

Trying not to sound to silly but exactly what parts would I need please.
And I really appreciate your help 👍.

It's all in the link I showed above.
But remember I live across the pond so it is all "American" and not metric parts.

the water cooler unit has 2 jobs, it helps cool the oil and also helps the engine warm up a little quicker so bear that in mind. also ideally you want a thermostat in your air cooler system, otherwise your oil will be too cold most of the time in the UK climate. a low-tech way around it is card in front of the oil cooler rad when you're not using it

That was the Standard how to keep warm in Illinois in the winter in my Bug-Eye, and MG Midget, I would also take the Fan off if it was to be in the teens for over a week or so.  

Some useful information there. That why I like to ask about certain thing because asking other people they sometimes know or see stuff I have missed. I'll see how it goes with removing it and keep a close eye on thing. And if need be ill evolve from there.
Thanks again 😁👍.

to be fair I bypassed mine when it popped for a fair while as i was planning on a 2.0 swap later on down the line, I didnt really notice any difference in temps. but then I dont track it or anything just a daily fast road car
