cols110 Posted January 7, 2007 Share Posted January 7, 2007 G`day all, anyone fitted an oil cooler in their power steering return line. I`ve had a few ocassions where my oil has been very airated, I don`t think it has actually boiled as the fluid seems OK, I am thinking of fitting a small cooler in front of the radiator to see if it helps at all, I think the problem is more related to high RPM than actual heat, as my TD5 spends a bit of time on the limiter, sometimes it actually overflows and blows a bit of fluid out of the reservior, as well as a squeeling sound from the steering box. I am hoping with fitting a cooler the extra oil capacity may also help a bit. Anyone done anything similar and can shed some light on if it made any difference or not. Thanks Quote Link to comment Share on other sites More sharing options...
mwncidur Posted January 7, 2007 Share Posted January 7, 2007 I ran one on my old racer, lock to lock and flat out used to make it puke its guts everywhere. Once the 13 row cooler was fitted I never had a problem again. Quote Link to comment Share on other sites More sharing options...
honitonhobbit Posted January 7, 2007 Share Posted January 7, 2007 I fitted one on my old hybrid, cos I had an early MM I used the oil cooler out of a vauxhaull Astra 1.7TD Quote Link to comment Share on other sites More sharing options...
David_LLAMA4x4 Posted January 7, 2007 Share Posted January 7, 2007 Just stick a 13 row cooler in the return from box to res. hose... and while you are on put a remote oil filter head inline as well and the components will all last longer!" Any hydraulic system that has to earn a living has a filter in the system so why not give this benefit to your steering? It is amazing how red the fluid stays without developing that ';metallic; sheen to it when a filter is used to catch all the little bits of metal in the sytem...

Turbocharger Posted January 7, 2007 Share Posted January 7, 2007 To look at it another way, why not alter your gearing to bring the Td5 revs down? A Disco transfer box is cheap enough and you could see other benefits in fuel consumption too. I'm thinking that you're solving a symptom, not the cause.

Mark90 Posted January 7, 2007 Share Posted January 7, 2007 If he's driving a TD5 in the sand he'll have to use all the revs he's got. Quote Link to comment Share on other sites More sharing options...

David There is a membrane filter type thing in the bottom of the round ZF reservoirs. I read (on here i think) it's a service item so replaced mine a few months ago. (I broke the old one up to have a look inside and it was fairly choked with goo). Not sure if the aftermarket aluminium reservoirs have internal filters, if not an external one would be essential Quote Link to comment Share on other sites More sharing options...
jules Posted January 8, 2007 Share Posted January 8, 2007 Both the race Freelander have modified factory coolers due to it over heating the ATF. The 90 used to suffer on events with the fluid boiling up all the time with the big tyres and my driving style. Its the work the pump and box are doing not the engine...

cols110 Posted January 8, 2007 Author Share Posted January 8, 2007 Thanks all, it makes for some interesting reading, I think a big cooler is the go then, and I like the idea of the filter, will look into the a bit more, as it certainly can`t hurt to throw one in at the same time, and it will also increase the capacity a bit more. As Mark90 mentioned, gearing is`nt the problem, I need to keep the TD5 reving pretty hard in the sand, it sucks all the power you have and more on a decent climb in soft sand.
