v8bobber Posted February 6, 2009 Share Posted February 6, 2009 All, I have finally sorted out the cooling system and i'm waiting for a fuel tank to be made i'm going to try and put the ancillaries back on. Steering box, piping and reservoir are all on/in and I may well make some mountings for the radiator this afternoon. Whilst searching through the pile of bits that came off the donor disco I saw the auto-box oil cooler that I had been trying to forget about. No doubt that I can get the cooler itself to fit somewhere, the piping is going to be a problem I think as firstly the pipes are formed and will not fit in this application. Also, it seems that the orignal pipework went via the radiator aswell as to the "bog brush" cooler". Does this mean then that the cooler on it's own will not be sufficient to cool the box? The engine is a standard 3.9 and the box is HP22 auto from a disco. It will be used for trialling and will obviously only really run for short periods. I also have the problem of sorting the pipework out - like i said, the radiator is now a non standard one and I have two loose ends! Also the formed pipes will not fit. So, any ideas? I did think about taking the lot down to the local hydraulic specialist and asking him to make some pipes up for me - would that work? Hope someone can help - get yr thinking caps on CHeers, Dave Quote Link to comment Share on other sites More sharing options...
Orange Posted February 6, 2009 Share Posted February 6, 2009 I moved the standard bog brush cooler on a 3.9 and just popped into the local hydraulic place and got them to make up some hoses to suit... There is a thread in the tech archive about it so you can see what went on. My move was only from the bottom of the rad to the top in order to get a winch on, but it's the same principal. Mount the cooler, then measure the pipe runs and get them made to suit. Can't help on the rad/cooler interface issue as I retained all standard parts...

Nice one, I had u a think about this one whilst I was out and about looking for some box section (you wouldn't believe how hard it is to get some on a Friday afternoon!), and was wondering what pressure the fluid is in the cooler. Is it the same as in the box or is it at a lower pressure? Can you remember how much the hose was? If its going to be a case of moving it completely I might even move it into the back out of the way Ta, Dave Quote Link to comment Share on other sites More sharing options...
Orange Posted February 6, 2009 Share Posted February 6, 2009 The original thread I did is HERE IIRC, the pipes cost quite a bit, but the place I used like the folding stuff. Still expensive, but a whole lot easier than sodding about trying to make stuff up out of odds and ends. The pressure you are dealing with is quite low, but it will still squirt oil 10/12 yards if you forget that the cooler is disconnected and try to start the car!! Depending on what other mods you are planning to do to your motor, it may be better to lose the cooler in the back and get the pipes made up just once. Otherwise, you'll end up changing it in a couple of months and have to do it all again!! Quote Link to comment Share on other sites More sharing options...
bishbosh Posted February 6, 2009 Share Posted February 6, 2009 Auto box pipes only need to carry about 1 bar IIRC. Anyhow, I made my own hoses (second time round ) using barbed fittings and hose clips. The hose needs to be ATF compatible though as some rubbers will degrade and block your autobox valves. Makes life really easy as you can route the hose wherever you like, cut to length and bung on the end fittings. Quote Link to comment Share on other sites More sharing options...
v8bobber Posted February 9, 2009 Author Share Posted February 9, 2009 Guys, Finally found a solution. The oil cooler could only go in one place because of the location of the steering box, steering resevoir, pipework, radiator etc etc so made some brackets up and mounted the cooler halfway between the bottom pulley and the water pump. The original passenger side pipe luckily fitted straight up and all that's left tomorrow now is to get a 4ft hose made up and away to go. If I ever get round to reading the thread about posting pictures i'll put a couple on. Regards, Dave Quote Link to comment Share on other sites More sharing options...
