I had a progressive loss of coolant so I was getting through about a litre every month and increasing. No oil in water or water in oil but couldn't find leak. I daren't take a long run in case I boiled it dry & warped head. I was budgeting ready to replace all the hoses and coolant pipes under cabin for SS. My son used a pressure kit and took quite a long time with the engine cover off to show a small leak in a bypass hose in the space between the engine and the cabin bulkhead. He cut half an inch off one end and reconnected the hose. Problem solved & cost nothing. I haven't needed to put in any coolant for nearly a year but I still check regularly. For me this illustrates the challenge of owning a F/TF. I could have spent a packet and still missed the problem. It can be a financial black hole or the cheapest and most fun sports car easily available. The challenge of the latter is part of the fun of owning it.

I bought a pressure testing kit last year, and for the price, I think it may be one of the best specialist tools I have bought to date.
Could save you a fortune in time and money if you start losing coolant.

Nice cheap solution. Well done.

As an Official Old School Master Bodging Old Codger, I have to admit to pressure testing cooling systems for leakage for years: never bought a kit: married a Schrader valve to a rad/expansion tank cap and pumped 'er up to about 15psi max with a foot pump. (Or just over 1 bar gauge for moderns) or >2 bar Absolute for physicists..... Have to put that in or Mr Aiketgate will pull me up.

Still have a rad cap in me box of bits....remember metal rad caps? ....from the days before expansion tanks, with a brazed-in Schrader valve.... Possibly may not use it again, but, as we say, y'never know....
