Cchase Posted August 5, 2016 Share Posted August 5, 2016 I am removing the 2.5 N/A from my Defender 110 to be refurbished (something about low oil pressure and finding shiny metal stuff in the sump...) What part of the radiator is the oil cooler? I am thinking that it is just the right side 'post' of the rad, but have not been able to find any diagrams that separate out the coolant part of the rad and the oil part. Any diagrams or insights would be appreciated. Also, the hoses to the cooler seem to be fine. What would I look for to decide to replace these or not? The truck is a 1995 ex MOD 110 with 112000km. The motor was rebuilt in 1997 with big end bearings and cam bearings replaced (+10), but no piston enlargement. (according to the tag on the fan cowl).

Kevm Posted August 5, 2016 Share Posted August 5, 2016 As far as I am aware the cooler part is just in the R/H side, good idea to give it all a good wash out if you have metal bits floating about. Check the hoses for cuts/damage to the outer rubber, if there is a straight end you should be able to have a look inside, wash them out and blow through them with compressed air, but if they look ok and not perished they will be fine. If you need new maybe a local hydraulic hose place would be cheaper just make sure they dont make smaller bore ones. Quote Link to comment Share on other sites More sharing options...
stephencdavies Posted August 5, 2016 Share Posted August 5, 2016 lay the rad down and pour some diesel in the oil cooler. leave it over night or as long as you can. this will clear it out nicely. Quote Link to comment Share on other sites More sharing options...
western Posted August 5, 2016 Share Posted August 5, 2016 oil cooler is a tube within the radiator right hand side tank, it's not a seperate or accessible part. Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted August 5, 2016 Share Posted August 5, 2016 I didn't think the NA had or needed an oil cooler. Quote Link to comment Share on other sites More sharing options...
Cchase Posted August 5, 2016 Author Share Posted August 5, 2016 Thanks for your replies and advice. Having the oil cooler as a tube running through the engine coolant is an interesting way to get the job done. Cheers, Colin Quote Link to comment Share on other sites More sharing options...
Eightpot Posted August 6, 2016 Share Posted August 6, 2016 The oil cooler on an ex mod n/a is normally a separate unit bolted in front of the radiator Quote Link to comment Share on other sites More sharing options...
