310R radiators

[Graham Hutton]

Following a previous discussion on here, I have just replaced the radiator in my 310R with a new 60mm RadTec unit. What a difference to the standard unit! After 3 lead radiators, this looks like the business and certainly feels a heck of a lot more robust. I spent a good while to ensure there s no tension in any of the mountings or hoses too and am v pleased with the result. Just a quick note for anyone doing the same, you need a new top hose ideally as the RadTec unit stands a little bit further away from the engine and my existing one was a bit marginal on length.

Anyhow, as a side effect, I now have tow genuine 310R Caterham radiators and a fan unit all packaged up in a box which I am happy to sell to anyone interested. The only problem is that they both leak!! Minor sweating on the welds on the top corner for both of them. If anybody on here is an expert in welding up aluminium radiators and wants them, let me know.

Thanks to everyone that contributed to the original discussion!

What's with the air filter on the catch tank?

[Graham Hutton]

Well spotted! The catch tank was driving me nuts because there was always a thin film of oil on that side of the engine bay and drips from the bottom of the standard vent tubing which made my car messy!!!! This little crank case breather filter has worked a treat in tidying everything up. It is really close to the top hose though, hence the rubber tape to make sure it doesn't cause abrasion. Eventually I'll fit a better catch tank but for the moment it works great.

Mine has the drilled cap to vent (although I have never had any oil residue outside the tank). I think the newer cars have a vent pipe to underneath the car instead which would avoid the possibility of an oil film.

My 2020 310R has a vented cap too and I don't get any oil in the engine bay. It doesn't have a vent pipe.

I do 3 or 4 track days a year and only have a couple of mm of oil in the tank at the end of the year.

I think mine only discharges into the the catch tank when the oil level is right at the max and on track. I don’t think it generally has much in the way of oily vapour going into the tank.
