Does anyone know what size the threads are on the fittings for the oil coolant lines (94 disco)? I would like to replace the stock with stainless braided hose. |

Fittings are of the "bumped tube" variety, so if you really have your heart set on it, you'd be better of using a tube connector hydraulic fitting and then just cutting the factory hardlines about 2" back from the nut and reusing them.
BTW - forget the s/s braided hose - that gets you nothing that 100R1AT hydraulic hose won't provide at about 1/5 the cost.
Also - you'll have to support the hose if you do away with the factory hardlines - those bungs brazed into the tanks won't appreciate a few feet of hose hanging off them - they will crack eventually.

What about replacing the bump fittings that screw into the radiator to allow use of JIC flared fittings? The fittings on the radiator appear to be NPT.
The lower •••••• line has quite a bit of weight hanging on it virtually unsupported. Seems like they didn't design much of a strain relief. Same with the oil lines as they come off the radiator and are tied together with the flex line looking as though it might even be putting additional tension on the fittings.

Converting to JIC would be cool - I was just trying to make a suggestion that would be quickest. Maybe the rad's are different by years (?) - but the thread on mine was a straight thread. I've never really looked at an earlier years rad.
Maybe it's just my own caution - but in general, unsupported hose is not a good idea - especially in something that can see a lot of jarring. Also - the hose will weigh about probably 3-4 times as much as the hardlines (approx 1/4 lb/ft). Anyhoo - I though the hardlines were pretty well supported and am just cautious about hose routing/support (comes with the territory with my vocation I guess)

I don't know what year yours is, but I have quite unfortunately gotten to know Rover radiators pretty intimately. On those I've worked on, there was no gasket beneath a boss for a straight (is british parallel pipe the correct designation?) pipe thread sealing, rather, they appeared to NPT and had pipe dope on the threads. It was my understanding that BPP threads required a flat boss above the threaded portion to provide a sealing surface for the gasket or O-ring.
Either way, I'm going JIC so I can build a manifold for pressure and temperature sensors for both •••••• and oil. Maybe add a spin-on filter for the •••••• so I can have an easily accessible filter for more frequent replacements. |

I was thinking of using the JIC flared fittings and screw them into the radiator and at the connections near the oil filter. I saw a similar kit on a RR Classic that looked real nice. The hoses required a different set up on that as there was a connection plate at the oil filter for both oil lines. This kit was supplied from a rover accessories place, but very $$$$. I found someone to build them, but just needed to know what size the thread was.
I'll keep looking and let you know. |
