Jonathan, Thank you for your quick reply. I have not removed the thermostat so not sure what temperature it is, other club members have suggested I remove it and check it has been modified (by drilling a relief hole) so as to reduce the thermal shock when it initially opens. The cooling fan cuts in and out as expected and the cap was purchased from Caterham online parts store with >PA66-GF30< embossed on the underside (I'll post the photo when I work out how to do that). It would be good to think it was simply an airlock (I don't currently have a T piece bleed in the top heater hose), just cannot figure out in mind how such a pressure can be generated to deform the radiator. Best Regards, Chris

I’m looking for your collective wisdom with a coolant issue that has got me stumped, with the well earnt reputation of the Rover K series head gaskets its I guess I’m thinking that maybe the issue but before I go down that route looking that I have covered all option. Apologies in advance for the long post. Vehicle Superlight R fitted with the 1800 VHPD K Series with heater Symptoms On the road the vehicle performs well with no evidence of overheating or loss of fluids although does always appear to run hot (90°C on gauge). Each of the three trackdays I’ve done since owning the car has resulted in some coolant related issue. Trackday 1 – Car performed well all day until the final session of the day when vapour traces was evident jetting from two pin holes in the (aluminium radiator). Radiator replaced with replacement ‘red’ coolant mixed 50:50 Trackday 2 – During the day spent time bleeding through the radiator (with the front raised), after each session the coolant level had dropped although no evidence of coolant escaping from the pressure cap seen. In the middle of the afternoon the top heater hose split releasing coolant. It was also noted that the radiator had ‘bowed’ on the top and bottom rails. Hose replaced and checks detailed below performed Trackday 3 – After each session traces of coolant evident around the expansion bottle from the pressure cap lifting. In the lunch break when the vehicle had cooled able to get a further 1.1/2 litres of coolant in the radiator by filling through the vent fitting (with the vehicle raised at the front). At the end of the afternoon session the cap lifted releasing qty of coolant. Work / Checks undertaken to-date Radiator replaced Vehicle ran up to temperature with pressure gauge in place of the pressure cap – no high readings (max below 1 bar) Coolant system pressurised through the expansion bottle to 1 bar, no deterioration seen over an extended period (5 days) Expansion Bottle Cap Replaced Suggestions Welcome suggestions on next steps, it feels like the system is pressurizing when used on the track. My next steps were to replace the water pump (deteriorating and not creating the necessary flow?) and thermostat. Reluctant to replace the head gasket as it appears sound with the tests performed above although is it heard of for the stretch bolts to stretch when hot releasing tension on the gasket then re-seating when cooled down? Appreciate any guidance you may have - once again, apologies for the long post. Thanks, Chris

Mark, Still with you Mark if you want them following John's recent note - let me know. 2nd Dibbs Nigel M 3rd Golf Juliet Tango 4th Joseph

Mark, Yes it is the type that uses the same fixings as the original screen, takes 10 mins to remove the screen and fit using the same bolts. Can mail you a photo of them fitted to my car if you wish, just drop me your e-mail address. Thanks, Chris 1st Dibs - Tweeky 2nd Dibs Nigelm

Howard, Is the one you have for sale the same as that on the Road Angel website as New Angel, if so approx how old is it? I assume it can be used from it's internal battery and does not have to use the power cable? Thanks, Chris

Hi David, Could you send photo's to chrisbequia@hotmail.com and log me for first dibs. What model was the heater fitted to, interested for a K series car. Thanks, Chris

How sensible does the offer have to be?! (Really looking for a pair) Chris

Hi Nick, Thanks for the posting - where have you sent the photos, have checked my hotmail account (chrisbequia@hotmail.com) but don't appear to have received them? There could be a problem with the size of the attachment, if this is the case could let you have an alternative e-mail address. Thanks, Chris

Can you send me a photo of these two wheels to chrisbequia@hotmail.com, assuming they look ok can I have first shout on these please. Thanks, Chris

Hi - are these wheels still available, I'm at the GP over the weekend so could collect then if I've not been beaten to it. Thanks, Chris
