Radiator and oil cooler tech

Can I get rid of the oil cooler somehow like say just putting plugs in the holes where the lines mount to the engine?

Can I just weld D90 mounts on top of a Range rover classic radiator without an oil cooler and make it work?

I removed my oil cooler lines and plugged the holes when mine started to leak. I have not had any problems and it has been about 8 months. I think Rob replaced his also maybe last august.

Wait..... just to make sure you don't blow up the engine!

You can plug the holes in the radiator, but on the engine side of the oil cooler lines you need to remove the sandwich plate that bolts between the filter and the oil pump itself! Don't just take of the hoses and plug the holes, if you do that on the pump you'll get no oil into the engine at all.

In order to do that.
1. Take off the oil filter
2. Where the oil filter threaded on, you will see a big nut underneath. Remove that nut.
3. The sandwich plate will now come off, this is the piece that the oil lines attach into the oil pump. Also make sure to remove any gasket too
4. You will now see another mounting surface to attach an oil filter. Put it on there as normal.

Ok so do I need a gasket Hans? Or just pull it all off and spin the filter back on what is left?

no need for a gasket, since you will be using the one built into the oil filter. And no change in what filter to use either. Just make sure to have an oil pan handy, since you will be dumping out all the oil that is in the cooler and the cooler lines.

Unbolt adaptor thing, screw back on oil filter--done.

Got it.

Thanks.

Is the same sandwich plate used on the 300 Tdi?

As long as I'm in the middle of a radiator swap I may just as well deal with this now.

Apparently there is no sandwich plate on the Tdi - the assembly is a right angle type bolted to the block. It also has a temp control valve.

Best leave it alone and just do the hoses. If I can determine the thread type then I'll replace them all, otherwise just the rubber.

Looking at the hoses, there doesn't seem to be enough length of pipe at the adapter end to fit to the new flex line. I don't know how the shop does it but I thought they cut off the existing barb and braze on a new one.

Am I wrong?

Usually, I think that is what they do, yes. But I wonder if you might be able to carefully cut off the crimped ferrule and the hose, without damaging the original hardline piece. More work, but if you use the original barb it should do ok.
