I've got a couple of annoying leaks. 1 i've found...the 2nd I dont stand a hope in hell without it pressurised as its hidden under bits on the engine.

Any makes to stay away from? maybe DIY of doing it? or maybe someone has one happy to let me borrow for beer money

(im based in poole in case someones close)

The other way is to us UV dye UV torch. Costs about £10 off eBay.

I presume you just want to pressurise it while cold so that you can check around for leaks. A cleaned out Eezibleed would probably give you the connections and pressure that you need.

If you have, or can get hold of, an old inner tube cut the valve out with a circle of the rubber.
Cut a metal plate and drill a hole for the valve to go through. (see pic)
Clamp this on to your rad cap neck and pump up with a bicycle or foot pump. (assuming no compressor)

The one in the pic is drilled for fuel senders. You don't want 125psi in an ally fuel tank.

The easy way to McGyver one is just to simply Tee connect to a small bore hose, this how I do cooling system pressure tests on Rovers which are prone to hard to trace minor leaks.

I use my home made cylinder leak down tester to supply the pressure (I will post a picture later) but you could use a foot pump, bike pump or even a garden sprayer.

In my case the hose bore is 8mm which would be just right for a Schrader tyre valve.

A car cooling systems are designed to operate some where between 0.25 and 1.8 bar so if you use a compressor set the regulator to give just below the pressure cap operating pressure.
