Yellow 7 Posted September 27, 2011 Share Posted September 27, 2011 Hi I have recently bought a 1997 Roadsport which I am thoroughly enjoying. At the weekend I took the nosecone off for the first time and noticed that the radiator is quite rusty and the coolant looks like it's seen better days. Before winter I would like to change the radiator, flush out the system and replace the coolant, and I am hoping that you can offer me some advice on how to do this and how's best to purge the system of air when refilling. The engine is a 1.6 K series supersport. Many thanks for any pointers....... Matt Link to comment Share on other sites More sharing options...
AlC Posted September 27, 2011 Share Posted September 27, 2011 I would (and did for my build) buy one of these to put in a high point of the system to help bleed once you've re-filled. I'm sure the seller is a fellow club member. Sorry, I have no experience of draining, but I'm sure others will be along shortly with some spot-on advice.

Member Jonathan Kay Posted September 27, 2011 Member Share Posted September 27, 2011 There's lots on this in the Forum, especially about removing air. I suggest you try searching, and then ask again if you need help. Good luck Jonathan Link to comment Share on other sites More sharing options...
Yellow 7 Posted September 27, 2011 Author Share Posted September 27, 2011 Thanks for the reply's - does anyone know if the radiators are Caterham specific or are they just a rover item? Thanks Matt Link to comment Share on other sites More sharing options...
makingff Posted September 27, 2011 Share Posted September 27, 2011 I did this earlier this year (K series 1.8vvc). Mine was running hot and no amount of fiddling was bringing the temps down. In the end I decided to get a new rad to see if this cured the problem. I went for a Radtec Extreme radiator (call them, they're are very, very helpful). Was going to fit this myself but chickened out and got Automotive Engineering (jj48 on here) to do it for me. Once the air was bled (read everything on here about how to do this and do fit a bleed tee if you have a heater - when people say be patient and wiggle hoses, they're not exaggerating!) everything was fine and the Radtec is excellent and keeps the car at a steady 80 on a run.
