Pressure Relief Thermostat (PRT) - How to Replace

It’s not necessarily the stuff that can be temperamental, it’s invariably the hands of the applier that won’t do as instructed. They are too large, in the wrong position & will not work when in the right, you are underneath with water dripping in your eyes, which are already half closed & the screwdriver is an inch out of reach & can only be retrieved by wriggling out & starting again. I have a pit in my garage but insufficient spring left in my legs to get out once in, however the above still apply to me although I can sit on a small stool & that means craning my neck (not good) whilst the jackers up can lay on their backs.
If you start off MG ownership hale & hearty with a determination to look after it yourself, you will soon accrue some small disability, in addition to cuts, abrasions, burns & bruises.

Sorry Matt just a day late. If you have a rag top roadster & the sun is shining you take full advantage of both. Right the PRT picture I promised.

Is there a specific VIN or date, when the PRT was taken into use as standard?

There's no point in discussing ''standard'' with me, standard things inspire me to change them & lean on route.
