Martin7H Posted March 17, 2013 Share Posted March 17, 2013 Hi What is the correct antifreeze for a VX C20XE HPC. I am also going to replace the hoses for silicone ones. Thanks Martin Link to comment Share on other sites More sharing options...
combine Posted March 17, 2013 Share Posted March 17, 2013 I put normal car anti freeze in , seems to work fine as long as the water/anti frreze mix is strong enough . Link to comment Share on other sites More sharing options...
Martin7H Posted March 17, 2013 Author Share Posted March 17, 2013 What do you mean by normal antifreeze, as there are quite a few variants. What brand do you use? Link to comment Share on other sites More sharing options...
keybaud Posted March 17, 2013 Share Posted March 17, 2013 I spent ages trying to work out which one and eventually I chose the Halfords own brand red stuff for my Vx, as it's suitable for alloy heads, etc. Edited by - keybaud on 17 Mar 2013 20:35:03 Link to comment Share on other sites More sharing options...
Rob Walker Posted March 18, 2013 Share Posted March 18, 2013 following problems with my ali rad I was advised by Radtec not to use the latest longlife anifreeze the stuff with OAT in ( organic acid technolgy) They claim it corrodes the ali. The engine block and rad were black inside after using this stuff and where some coolant had leaked out it has corroded the ali body side skin on my car.

combine Posted March 18, 2013 Share Posted March 18, 2013 How many anti freeze variants are there ? Bought a 20L can from my local garage , think its Morris anti freeze , thought the ingredients were the same as other makes ? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 18, 2013 Member Share Posted March 18, 2013 Ethylene glycol Propylene glycol A large number of additives for a large number of purposes: corrosion inhibition, increased wetting, colour, taste... Jonathan Link to comment Share on other sites More sharing options...
combine Posted March 19, 2013 Share Posted March 19, 2013 So are some not suited to car engines or do they all do the same thing ? Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted March 20, 2013 Member Share Posted March 20, 2013 Wikipedia article on antifreeze I'm aware of two current questions for 7s: 1 The best coolant for K series engines. This is mostly about preventing corrosion to the aluminium. (I follow the factory instructions.) 2 Whether wetting agents improve cooling. (I follow the factory instructions.)

MereCat Posted April 19, 2014 Share Posted April 19, 2014 Hi Jonathan Just picking up on your response. What are the instructions / guidelines for a K series? Thanks Paul Link to comment Share on other sites More sharing options...
Member Jonathan Kay Posted April 19, 2014 Member Share Posted April 19, 2014 Here's what I'd put in a K series:Quoting Jonathan Kay: 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.Discussed here and here. My own answer to the questions I posed are "Factory instructions" and "Possibly, but not needed in addition to what's in the recommended commercial products".

andy couchman Posted April 19, 2014 Share Posted April 19, 2014 ...or switch to Evans and cut out the water bit. Andy Link to comment Share on other sites More sharing options...
Baz Hemsley Posted April 19, 2014 Share Posted April 19, 2014 I find blue is a much nicer colour. Link to comment Share on other sites More sharing options...
MereCat Posted April 20, 2014 Share Posted April 20, 2014 Thanks Jonathan Baz gone with the red for now. Cheers Link to comment Share on other sites More sharing options...
LesG Posted April 21, 2014 Share Posted April 21, 2014 I use the red stuff with no water in it, matches my car's colour scheme! 😬 Link to comment Share on other sites More sharing options...
