There's me thinking everything was going to be sorted ready for my MOT retest tomorrow. Got myself a new coolant temp sensor but to get the old one off i had to remove the coolant bridge.
When putting it all back on this evening i have managed to shear one of the big bolts holding the brisge in place, the hollow ones with the 4 holes along it's length, i actually thought i'd stripped the thread in the engine block at first so it was a relief to find out it had only snapped.
By the looks of it the metal around one of the four holes in the bolt must have already been cracked as it's already corroded rather than being bright metal as you'd expect from a fresh break.
What i want to know is do these bolts have a torque vaule applied to them, and if so what is it?
Hopefully i'll be able to make a new bolt at work in the morning as the scrappy where i got the sensor from is a fair distance away, depends on if i can find the correct size bolt to start with
Bit of a bummer as i'd hoped to have everything back up and running today. I do hope i can get my retest re-scheduled though, don't fancy spening another £50
