Ainsley Posted May 23 Share Posted May 23 I'm picking up my 420 R on Saturday and have a couple of questions: Tyre pressures. What is the normal coolant operating temperature. What is the normal oil operating pressure. Thanks. Link to comment Share on other sites More sharing options...
SM25T Posted May 23 Share Posted May 23 Many tyres are 18psi when cold. Assume a Duratec ... Coolant temperature probably 90-95 ? Oil pressure .... Probably 4-5 bar cold or at revs. 1.5-2 bar when hot and idling Enjoy it. Careful with your right foot. Wear narrow shoes. Wear hearing protection.

Chris SSR400 Posted May 23 Share Posted May 23 My Duratec runs just over 2 bar at hot idle. Coolant temp will depend on the thermo you have fitted some run a little cooler some a little hotter so 85-95 I'd say. I hope you have the long route home planned? Weather Saturday looks to be on your side (well at least it is up here in the north) Enjoy! Link to comment Share on other sites More sharing options...

Coolant temp when driving is around 95C - fan should cut in at 100C Oil pressure is rev dependent - idle is around 2.5 bar, goes up 4 bar with higher revs. Enjoy your drive!!

Same goes for not switching on the battery master switch. 🤦♂️ Edited May 24 by Chris SSR400 Link to comment Share on other sites More sharing options...
Ainsley Posted May 24 Author Share Posted May 24 Ah, keys in the pocket 🙂 When I had a hired Caterham last year, I did manage to leave the removable steering wheel just out of reach in the middle of town, with a collection of grinning onlookers. 1 Link to comment Share on other sites More sharing options...
