Oil Coolers - help needed :)

Chris_Rogers · Post by **Chris_Rogers** » Sun Aug 19, 2007 8:45 pm

this is for my L TT wagon :

ok I have 3 of these all taken from falcon sedans (2 of which are from taxis)
one is 6"x5" (taken from a EL falcon)
one is 6"x11" ( EL falcon taxi)
one is 8"x11" (taken from a AU taxi)

now the Legacy I used had one in the radiator for the trans and a tube one for the P steering.

what I want to know is what would be the equivalent one to use for the trans cooler (I know bigger is better but space is getting me.) and the equivalent one for the steering cooler?

placement is teh other issue. if its down the lower corner I can't see it getting a lot of air flow. top right would do nicely as it has direct airflow through the grill.

I figured it everything was cool it would last a lot longer.

thoughts..

cooler 1:

cooler 2:

cooler 3:

OE PSt cooler

the top one is where I intended to put it and that one is the intended PS cooler. one of the others will do trans OR I'll get another one of the small ones.

thoughts??

Can I ask - in what way would it make power steering cooler? What does it improve on?

unsure really . I figure it has to do with reliability. donor car had it so I was intending to put it back.

theroetically the surface area of cooling wuld increase (i no wt i mean lol probly not worded to well but)

i reckon a PS cooler in the lower corner liek the pic shuld be fine as the OE lines only go across the bottom anyway dont they

for the tranny cooler are u keeping the radiator cooler aswell? also i dont think ud need one to big for either of these applications
maybe the small one for PS and then the middle one for Tranny
wt bout puttin in a Engine oil cooler

To me - I cannot see if Power Steering would improve its cooling if it was cooled down.
I can see big difference between without & with transmission coolers (for automatics only) specially worn transmission that I had in the VN Commodore I used to have last year as I couldn't reverse while engine/transmission was hot so I added transmission cooler - problem was solved and had no problems till I sold it -> haven't heard if the new owner has problems!?

I am using solely the smaller EF falcon cooler at present without radiator to warm it up on my GLTA, might have to swap it with my mates EF former taxi if it is bigger, before he sells it. With your power steering, sometimes just a big loop in metal is used as a cooler. I think fluid quality is an issue so a filter may be worth looking at for both auto and p/s.

it was mentioned earlier about the oil cooler. going to do that. PS I intended to do anyway - was looking at sizing for it. trans cooler is a definite. learned that from my V8 days.

filter I didnt think about on those.

thanks for the tip.

i should hope his transmision will have a Filter in it all autos shuld most being inside the pan but some mitsubishis have them as an outside filter cartridge

and only some PS lines do have a filter, a kind of inline magnetic filter
they tend to leak alot over time and people dont see a need to replace them for some reason so they always become innefective (thats from what ive learnt at work)
but if u put a PS filter in it wuld help last longer (coz thats wt u want)

no the new custom alloy radiator wont have it in there. trans cooler is the only real issue. I can't put it on the left side as the A/C lines are there. top right I can do but mounting in will be a bitch.

lines originally ran up high in the grill airstream. where I have it now its obscured by the bumper - puttting it up top fixes that but its tight with both in place.

engine oil is going to be done - twice! one for each turbo. placement is going to be a pain though.

I'll pop the smaller of the two big ones in place and take a snap then work out the lines. (trans lines are right at the back so custom steel lines are needed )

thats what I thought ( last auto I had in bits was a chev 4spd.) the trans is coming out anyway so I'll get that looked at.
where do I find a PS filter though?

not sure on where to find a filter for PS ive never replaced one but id think someone like Repcos, Coventrys, Autobharn (might do we dont have em over here but) shuld have one
ermm just have to look around
my bros VN commodore has one (which leaks lol)

but dunno really never had to get one or replace one so just haev to ask around maybe someone on here nos where
