eharding Posted July 30, 2002 Share Posted July 30, 2002 I'm trying to get some information of replacement radiators for a Caterham 7 (on behalf of my brother-in-law). The car is a 1994 Rover K-Series 1400, rebuilt on 1996 at the factory on a 96 chassis. The car is currently in Cyprus, and the radiator has just failed. I've checked the Caterham website and phoned the factory - they have a standard radiator for 184 or a race radiator for 260 both plus VAT. Does anybody have any experience on cooling ability, durability and any fitting problems of the race radiator vs the standard road item (bearing in mind it's in the high 30s Celsuis in Cyprus right now an apparently the car would rarely register less than 100 degrees C on the temp gauge, but that might also relate to the age of the old radiator). Also, the factory mentioned something called an 'Air-Oil Separator' which might help with the cooling - does anybody know how this works, and whether it would require major engine surgery to fit such a thing? regards, Ed.

scooby dooby doo Posted July 30, 2002 Share Posted July 30, 2002 the race rad will fit ok. you could get the race fan as well which fits on front of the rad and so requires a bit of modification to the nose to make it fit. You cut a bit of fibreglass away but uts all behind the grill so you can't really see it. thwe apollo air/oil separator won't really help with cooling. a separate oil cooler and oil water intercooler will though. i suspect lots of threads on this exist - look for 'laminova' in the search window.

Fred Posted July 30, 2002 Share Posted July 30, 2002 this is a alternative race radiator very good price and works well here fred Link to comment Share on other sites More sharing options...
edmandsd Posted July 30, 2002 Share Posted July 30, 2002 If you go for the race rad I'd recommend you replace the plastic bungs with something a little more durable. Link to comment Share on other sites More sharing options...
scooby dooby doo Posted July 30, 2002 Share Posted July 30, 2002 the race rad bolts directly to the chassis if you have the big fan - otherwise it wouldn't fit in the nose. the race fan is a BIG thing ❗ HOOPY Link to comment Share on other sites More sharing options...
Chelspeed Posted July 31, 2002 Share Posted July 31, 2002 Not sure about this alternative rad, who'd trust anyone who powdercoats their anti roll bar red? If you had the old copper core, brass tank (heavy!) rad and temps were OK then the small alloy road rad will be OK. If cooling was marginal before then the bigger (used to be called race) alloy rad will give you a useful extar bit of cooling. Either will fit the chassis and in the nose without modification. If you're using it on the road then the standard electric fan (sits behind the rad and sucks) will be fine. If you're racing and slipstreaming a lot then the race front mounted blowing fan will help but a lot OTT for the road. Likewise don't think the anti cavitation, apollo, air oil separator will make any difference whatsoever to temps. Link to comment Share on other sites More sharing options...
eharding Posted August 2, 2002 Author Share Posted August 2, 2002 Thanks for the replies everybody - I'm off to the factory this morning to pick up a replacement. Cheers, Ed. Link to comment Share on other sites More sharing options...
