Was nipping to the local motor factors about an hour ago to get some pads for my track toy. As i have a rather large dose of Cosworth paranoia

i always have my heaters on hot and number one, with the drivers vent blowing on my hand

Just approaching a bit of road i ALWAYS give her death down and the heaters suddenly start blowing cold
luckily there is a petrol station about 50 yards away, so i coasted in there, popped the bonnet and supprise supprise no water in the header tank

It took 5 pints to fill her up

Bled her through and hey presto got heaters again

Looked for leaks but could not find any
Going to have to have a good examination tomorrow, any one else suffer the strange Cosworth paranoia were the stereo is always on low so you can hear if thing falls off
