Disposing of antifreeze

A question for those that look after their own cars. How do you dispose of old coolant? Given that it needs changing every 2 years, you quite quickly end up with a lot of it, especially if you flush the system too and get a 2nd fill of dirty water out. The local tip take waste oil, but don’t have a ...

Re: Cooling Fan Relay location

Interesting. In the S2 originality sticky thread, it shows it facing down too, but that car doesn’t have the coil bracket as the coil is on the cylinder head. Maybe it’s wrong on the JCNA guide then, or maybe it changes when the coil moves to the front frame?

Re: Cooling Fan Relay location

The JCNA guise shows it where Ash has his, but with the bracket facing up. The bracket on mine mounted on the other side of the frame, but may well be wrong as some of the fan wiring and relay was missing when I got the car. https://www.jcna.com/sites/default/files/files/e-type2(2).pdf page 9 in the...

Mine is on the top of the picture frame, other side to the coil.

Sounds good - which rolling road did you use?
Sorry Richard, missed your reply. I used Project Heaven in Kings Cliffe.

Re: rolling road figures

My car is on Webers, so no standard intake system. The Weber intakes are similar to Number 10 in your diagram. The longer the intake runner, the better the volumetric efficiency at lower rpms. There’s a useful illustration of this for the XK engine in “The design and tuning of competition engines” b...

Re: rolling road figures

I took my car to a rolling road today, as I think I’ve got as close as I’m going to by setting things up at home. It’s a scary experience watching someone thrash the tits off your pride and joy, but fortunately it didn’t blow up in the process. The initial run generated 204.3 BHP at 4022rpm, and 371...

Re: Starter tried hard to run the car into a wall.

The 6RA relay in the charging circuit was new when I got my car, and that’s the only one that’s given problems so far. All the originals have been fine.

Re: Starter tried hard to run the car into a wall.

What was the original relay? All the Lucas 6RA relays look superficially similar from the outside, but have differing pin layouts and internal circuits depending on their intended functions.

Re: Dragging brakes.

The front pads were changed 4 years ago, the rears were new last year when I did the IRS. I forget the make of the fronts, the rears are what SNGB sell as OEM. I will clean up the front calipers and check everything is free. I don’t believe it’s mechanical binding though. Cracking off a bleed nipple...

Re: Dragging brakes.

Sorry, my typo. Meant to write the front brakes are fed from the primary circuit on the servo, the one nearest the vacuum diaphragm, i.e. the same circuit as the master cylinder.

Re: Dragging brakes.

That’s a possibility, but the servo hoses are recently replaced, and with proper vacuum hose. They’re also insulated with aluminium corrugated insulation hose.

Re: Dragging brakes.

The brake fluid is only 12 months old. All replaced when I rebuilt the IRS last year. Similarly, rear calipers were rebuilt when that job was done. The reaction valve piston was removed and cleaned a couple of years ago, but I don’t think that’s the cause as the reaction valve was seated when I took...

Dragging brakes.

Has anyone experienced sticking front calipers on the S2, particularly with high ambient temperature? I went for a drive yesterday in the 35degree heat. I wasn’t driving quickly, very slowly if anything, as I was with a group of several other classics, so not more than about 40 mph, and certainly no...

Re: 123 Tune which Coil?

Having a better look at the curve you’re loading, it has a lot more advance at idle than the original factory curve. I suspect this curve is for an engine that’s some distance from standard. Possibly one with Webers, they like a lot more advance low down. Unless your engine is substantially differen...

Re: 123 Tune which Coil?

The distributor rotates at half engine speed, so you double both RPM and advance from the workshop manual figures to get crankshaft advance. The app works on crankshaft degrees/rpm. Vacuum shouldn’t be doubled, but the advance value for if should. The figures in the workshop manual are in distributo...

Re: 123 Tune which Coil?

The 123 only measures advance beyond the point it knows. You have 2 possible approaches: 1, install it at TDC. The advance values in the graph will be the actual advance the engine has then. You’ll have to add the static advance in on the app. I.e. the first point should be 9 degrees, not 0 degrees....
