Hi guys
its one of these: [img:600:425]

I broke the bottom part of it (just underneath the knurled screw thingy which the small rubber hose attaches to.

I think I will seal the bleed valve by tapping a screw into the remnant of the plastic takeoff. And then fit the un-mashed up end of the rubber hose back onto the steel pipe, and seal that with a bolt in a similar fashion...
Until if/when I get a replacement... I guess a hose of suitable diameter won't be too hard to find... Not so sure about the valve tho

I suppose I could hunt around for a piece of suitably sized metal pipe and jam it into the hole and just let the friction keep it there.
I wonder if the valve is bust anyway, I can't shut it off... discovered that when flushing water down the rad send hose, some of it returned via the engine thru the valve, instead going via the rad... turning the screw didn't stop it.
Unless of course that part of the valve is always meant to be open and its the connection between the main rad send/return hoses which it controls...?

Either way I don't think this alone could be causing the overheating...
That is if it is actually overheating

I am in denial now

but seriously is there a better way to test the temperature sender unit apart from dunking it into water of known temperature whilst it is still attached to the gauge? This is about the only thing I haven't done yet!!!
And just how hard is it to find a bloody thermometer that goes up to 100 deg C???
Oven thermometer not sensitive enough and can't be immersed in liquid
Body thermometer don't go high enough (not allowed to use mercury anymore it would seem!)
Room thermometer could but don't go high enough cos rooms never that hot
All the meat thermometers I found still don't quite go high enough.
Apparently I need a jam thermometer... where can you find one? Did some serious foot mileage round town looking for that... Eventually asked a local bakery who told me where they got theirs... But it was the weekend and they were closed! I'll get one on friday
