Redbullwings Posted June 17, 2014 Share Posted June 17, 2014 Having recently taken ownership of my k series roadsport I was a bit perplexed as to why the heater had been bypassed. So clever arse me hooked it up on Sunday evening to take wifey for her first spin (parents were over on baby sitting duty) Pulled out of the garage and my wife informed me of the warm wet sensation on her feet. Not what you might be thinking..... But coolant running down the bulkhead. As it was getting late I put the coupler back in and off we went. She loved it btw I've since spent some time with the heater partially out and a bowl under it and found 3 out of the 4 hoses leaking round the heater bypass valve. They leak where they join the metal, and two of them I can see that a new hose will probably sort the issue. The third is a bit more interesting. On the bottom of the bypass valve the pipe that has the 90 degree formed bend is out of round by about 1mm. You can fee a high spot on two sides of this pipe, and I can imagine how I'm going to get this to seal. http://caterhamparts.co.uk/product.php?id_product=333 I'm not sure if I have a duff bypass vale and others are perfectly round, or they are all like that, and I'm into the realms of gluing rubber bits on? Any suggestions would be warmly welcomed. Thanks Doug Link to comment Share on other sites More sharing options...
Area Representative paul richards Posted June 17, 2014 Area Representative Share Posted June 17, 2014 1mm out of round seems very little. A little persuasion should get it right and a very tight jubilee clip. Are you sure it is not coming from the heater matrix. There are 2 O rings inside the inlet/outlet which have a habit of leaking.

Stationary M25 Traveller Posted June 17, 2014 Share Posted June 17, 2014 Mikalor clamps are much nicer tham jubilee clips. Buy cheap at AFS hose supplies in Essex. Link to comment Share on other sites More sharing options...

Redbullwings Posted June 17, 2014 Author Share Posted June 17, 2014 It's definitely not coming from the heater matrix. In terms of the amount of out of round on a small pipe it's quite a bit. Anyone who has had the misfortune of doing domestic plumbing will know what a pain in the arse getting a seal on a miss formed pipe is. I've ordered a ramair silicone hose set which should arrive in a couple of weeks with their recommended pipe clips so will see how I get on with new pipes.

Grim Reaper Posted June 18, 2014 Share Posted June 18, 2014 Does the hose set include the heater valve to heater matrix pipes?? I'd be suprised if they did. Link to comment Share on other sites More sharing options...
Redbullwings Posted June 18, 2014 Author Share Posted June 18, 2014 The kit includes the 5 principle pipes and I added the two heater pipes and will add a bleed valve that I've got coming from eBay too. Went for the matching orange pipes, and quite looking forward to adding them as a bit of bling too. Link to comment Share on other sites More sharing options...
