JonL Posted May 24, 2013 Share Posted May 24, 2013 I am new to this 7 lark, as I only recently purchased by first Caterham 3 weeks ago (1.6 Kseries Roadsport) having wanted one since I was about 16 (almost 20yrs ago), so go easy on me. Anyway I am very happy with my purchase and have a stupid grin whenever I go out for a 'blat'. The only slight fly in the ointment is that I am leaking coolant ever so slightly from the hose connection of the 'submarine'. So far over the 3 weeks the level has only dropped from the max to the min level on the expansion tank. I have given the hose clip a tighten which should stop the drip, but I want to top up the coolant. I was going to go pick up a small bottle from Halfords, but wondered if there was a problem with potentially mixing different coolant types. Apreciate that this a realy novice question - I promise I am a very practical chap, but cars have alrways been a closed book to me. I think this is my oppotunity to learn.

charlie_pank Posted May 24, 2013 Share Posted May 24, 2013 You probably shouldn't mix different types of unknown coolant. How about just topping up with (soft, or pre-boiled) water? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted May 24, 2013 Member Share Posted May 24, 2013 You'll be fine. There's a lot of discussion about different coolant types but most of it can be safely ignored for your (and my) purposes for K series engines in ordinary use. If you post a link to what you're proposing to use (and if possible what's already in) we can confirm that it's OK. Jonathan Link to comment Share on other sites More sharing options...
JonL Posted May 24, 2013 Author Share Posted May 24, 2013 Not sure what is in there already. I bought the car from Caterham South so I assume it is there approved Comma coolant. I was going to top up with halfords own brand as they have a shop on the way home from the station, and it is also pink! (I assume that colour matching works with all types of car mechanics!)

Member Jonathan Kay Posted May 24, 2013 Member Share Posted May 24, 2013 I find the labelling on coolant very confusing. Caterham have Comma XStream XSM5L for £17.10 + p&p Amazon have XSM5L for £16.98 inc p&p Halfords have Comma XStream G30 (which is probably XSM5L) for £24.99 ... all 5L premixed. I'd get a big bottle from either Caterham or Amazon. Usual safety warning: this stuff is very poisonous. Keep it away from children.

JonL Posted May 24, 2013 Author Share Posted May 24, 2013 I have just found a Comma supplier where I live (Bennetts) so I will pick some up this afternoon. It is marginally more expensive than Amazon, but I can feel at ease this weekend knowing that I am driving around with enough coolant. Thanks for the info from you all, and the warm welcome.

Martin7H Posted May 24, 2013 Share Posted May 24, 2013 I looked at Allparts and Europarts for anti freeze. Both specified Comma G48 (green) for the VX C20XE engine. Martin Link to comment Share on other sites More sharing options...
