Just for info, I have listed it on PistonHeads anyone is interested or might know of someone looking for a 620 https://www.pistonheads.com/buy/listing/13425350

Check out the wanted ads, there is someone looking for a sub-£20k Caterham that posted recently.

Found it! Yes, there is a grommet right at the end of the passenger footwell leading to the filler plug. Thank you!

I think this is the bolt (circled red) but not sure, it's a 620s. The photo was taken from inside the engine bay, looking to the back of the car. (It's side on this time but thr image above is the right way)

Yes, I will definitely try and source GL4, thanks. Anyone confirm if this is the bolt I use to fill it back up? (Presumably with a long and thin hose). Also, my manual suggests the gearbox has a 1.9l capactiy. Does this sound correct? (I don't want to over/underfill)

Hi, I assume it is the standard 'Caterham Seven Owner's Handbook', it came with the car (which was manufactured in 2015). Page 24 reads: Gearbox oil: Sigma/ Duratec 5 & 6 SPEED EP75w90 grade / GP5 I was going to buy some at Halfords tomorrow but they only seem to have the above in GP5 so I will have a look somewhere else (I'm based on the SE corner of the M25 in Kent).

Also, my manual says gearbox oil ep75w90 GL5 but the little plate on the car says GL4. No idea what the difference is but should I trust the manual or the little plate?

...and how on earth do I get to it? (For reference, I am giving it a bit of a service and wanted to check the gearbox oil and replace it if necessary)

i am selling a 620s SV. It's a wonderful car! Link to my for sale post…

Sadly I think I am going to sell my Caterham 620s SV (nothing to do with the car but a change in circumstances). It is an incredible little car and wonderful fun on track as well as on the road. I am thinking of a price in the region of £49k (looking at others online) but very open to discussion about this. Only about 35 620s SV's have ever been made so these are somewhat rare to come up. I am going to list it here and see if there might be any interest from members or if you might know anyone. However, alternatively, can anyone recommend the best platform to sell the car (autotrader or similar)?

Anyone have a link to the 620 owners group on Facebook? I didn't know about it.

I'm not sure this is an issue as the fan kicks in at just under 100c and it seems to drop nicely as cool air can still flow in. However, I would remove it entirely in very warm weather.

I had previously tried to 'warm' my engine a bit using broad masking tape over the top section of the main radiator on my 620s but this had absolutely no impact. However, today I tried the suggestion from another forum thread of covering the rear of the radiator grill in the nose cone and this has had a huge impact on reducing cooling. The engine is now running fairly consistently between 80 and 90c whereas before it was literally between about 50c and 80c unless standing still. I bought a large piece of 'foam board' from hobbycraft and cut it down to about 153cm x 110cm and used small cable ties to hold it in position. If I use this longer term I might try and get some easy to remove fixings so that I can remove it in hot weather. Hopefully you can see it in the photo below, there is a horizontal line just above half way up the grill where the foam board stops. I will give this a better try on the motorway to the Caterham Cars open day on Saturday and report back.

Out of interest, did you buy the official Ford part or a different one, if different, which?
