Finally got around to fitting the auto box oil cooler conversion to my J spec, but also removed the pan from the box and replaced the filter. Also decided to do a engine oil and filter change, so all in all I got rather greasy today, but it was good fun :D

 

The cooler wasn't to difficult in the end, thank goodness I'd built some wooden ramps though otherwise I'd have no hope getting under the car.

 

Auto box was nice and clean as was the filter, but I changed the filter anyway whilst it was all apart.

 

Only did a short run to check things out but did notice the 'new' auto box rad got quite warm but the brand new engine oil coller was still cold. ill need to check this after a longer run, perhaps tomorrow.

 

Just got the rear diff to do another day.

Hi i am doing my oil cooler at weekend can you tell me how to fit as it came with no instructions its a mocal one mark

Bits in my kit:

 

New rad (replaces existing engine oil cooler)

2 x 90 degree connectors for the new rad

Adaptor plate

2 reducers

2 lengths of rubber pipe (for the auto box cooler)

8 jubilee clips

 

Firstly I had to remove the splash guards under the car which was fairly easy as I had done this a few weeks ago, but the first time I removed it, several of the bols sheered, so watch out for that.

 

I also have no grill on mine so have good access from the front, so undoing the existing small engine oil cooler is just a matter of undoing 3 bolts. I fitted the new cooler to the adapter plate that came with it (4 small bolts), attached the 90 degree connectors to the top (facing the drivers side) and then removed the pipes from the existing cooler and attached them to the new one (just loosely to start with). Once I was happy that it would fit in place I tightened the pipework. It's a bit tight in there but the old cooler bracket did bend fairly easily to squeeze in the new cooler.

 

OK so that's the new oil cooler now cooling the engine oil (not bolted in yet). One mod I also had to do was that my adaptor plate was flat and the old cooler and it's bracket was not, so I had to straighten the bracket (just used pliers) and the plate on the old oil cooler (used a mallet). This meant that the existing bracket, the new adaptor plate and the existing oil cooler plate all mated together in a nice sandwich ready to bolt together.

 

The pipe work for the auto box runs under the car and and attaches to the rad on the right hand side (facing the car). Trace the pipes until you're happy as I cut into mine at teh front of the car as it run under the main water rad as it was nice and easy to get to. Used the reducers in the kit to connect the new pipework from the kit to the existing pipes and then ran it to the old cooler and cut them to size. I flushed out the old cooler with some auto box oil just to ensure there was a good flow through. The old cooler now sits back to front with the 90 degree connector facing the passenger side and is bolted via the centre bolt through the adaptor plate (this is now between the two rads so is a bit fiddly to get to). I managed to get a second bolt in so it's nice and tight on mine.

 

I managed to remove one of the old auto box pipes, the other one I cut as close to the rad as I could.

 

Oh and be ready for a bit of oil when you remove the pipes and cut the auto pipes.

 

One other thing, when trying to find a route for the new auto box pipework I had to break a small platic plate in order to make a hole large enough for the pipe to go through where other pipework is, don't worry, I'm sure you'll spot it.

 

Hope it all goes as easy for you as it was for me.

Hi thats a big help gaz will let you know how i get on

The autobox rad does get very hot

which after feeling it i think nissan need a kick in the nuts for not fitting a good one as standard.

thought the auto cooler was conbined in the rad :confused:

if you have seen it you would realise that it was a pathetic attempt at humour from the japs

Definitely agree with that, I was very suprised how much hotter it gets than the engine cooler. Also the old auto box cooler sits down one side of the main rad so I can imagine it has trouble doing anything useful to cool the oil.

Thanks for the feedback znut. I've had a lot of good advice from everyone on the forum, the best £20 I've spent on the car, so just glad I can start to give something back.

Finally got round to a bit of spring lovin on the Zed today as well. Changed the oil, washed and vacuumed her. She's looking much happier now!
