There are two main factors at the basis of this. The radiator type and capacity is important, however the main culprit is the lack of oil volume with the engine running at higher than design revs.

Use of electric fans is assisting the radiator problem, however once the oil gets hot it takes a lot of cooling to bring the temp back down.

I advise all Holden powered Landy owners, that a good addition to the engine is an engine oil cooler, these are available from Repco and fit behind the standard spin-on filter fittings. You can use a regular transmission cooler element or a dedicated oil cooler type. Once fitted, not only does it cool the oil it adds additional oil volume which is a double benefit.

If you do a lot of off-highway work, particularly steep climbs and descents, you may want to consider exchanging the sump for one off an HT model. Most other model sumps have the bulge at one end and get oil starvation when traversing a hill where the bulge is up-hill. The HT sump is unique in that the bulge is in the centre and this allows constant oil flow irrespective of steep climbing or descending.

Does the oil pick-up need to be changed too?

yeah you would have to change the pickup aswell

Hi Banjo
I would spend the money on 1 good water temp gauge ie a VDO or similar.
