Diff oils / Coolant system pressure

[stephen low]

Hope some one can answer a couple of questions I have.

What capacity and oil type is recommended for the Jag LS diffs?

I have no idea what state the oil is in the diff of my s/h kit so am looking to replace it to be sure.

I presume it is simply a matter of removing the lower square bung to empty and filling via an allen key? headed plug from the top?

Any advice on this would be great.


Also am looking at what sort of heater I should put into the car. Was favouring an old round Smiths, Bosch or similar variant, but have heard that the coolant pressures of new engines, an AU in my case, may cause the core in such an old heater some grief to the point of failure.

Have I been fed a line here, or is this possible, due to increased pressures or simply the ageing core in an older style heater?

Please explain, as Ms Hanson would say.

Cheers
