I got the car back and had a chance today to try and localise the coolant leak. In the snow. Feels like -6!
I started out by making sure everything was dry (by letting the coolant level go low). Then went about sticking tissue paper all around the area of the coolant flange, above and below.
When you took the housing off - did you get a chance to look at the seat where the o-ring goes? If there is any wear, or damage, or muck, that could maybe lead to the seal not being properly formed when the sensor is clicked home with the clip?
Has it had a new flange housing on it?Mine warms up fine. The thermostat replacement pain was a couple of years ago now. The G263 sensor remains the most physically painful work I’ve done on the car.
Removing this flange was just an access horror and cramped hands and back and turning bolts with a spanner by 1/16 of a turn per action then turning the spanner over for the next 1/16th. That was the worst!
When I had the flange off I cleaned it and scrubbed it and checked it all over. Kitchen sink and fairy liquid. The gasket seat section looked good. Really good for such an old part.
It’s weird. I’m going to try one more sensor and o ring replacement with a tiny amount of silicone rubber grease to lube it on placement. If that fails the car is going back to the garage (or maybe the junk yard... ).

no... I only realised that would be a good idea to replace it AFTER I had put it all back together!
For less than £10 I would definitely replace that if I was dismantling this bit of the engine again.
But I’m not going to. Ever again. Nope!

I’m sure in summer it’d be a nicer proposition.
My fingers kept sticking to the metal bits whenever I took the gloves off to get into the fiddlier bits.
You are just lucky I didn’t appear at your door...

Which make thermostat and sensor have you fitted, out of interest? In case I’m ever foolhardy enough to give it another shot and finally sort out my slow warm up....
Sorry i fail to see any reason as to why you are an "Idiot"?I’m an idiot. New coolant flange and coolant sensor and seals ordered...
Why am I doing this to myself?

LOL that cracked me upI hate to admit this, but I was almost holding my breath towards the end of this thread waiting for the 'DONE IT' comment....its like a mechanics version of Eastenders....will it, won't it, who did it......
I have my fingers crossed that you finally sort it, I will watch with baited breath for the next round of 'dripgate'.
