Anyone using a coolant pressure tester? I bought the craftsman and it was a POS, the bladder popped up under test pressure, jeez. I heard that Stant is good but they don't have an adapter for LR as far as I know.

Anyone using the Stant tester or another tester and like it? Just returned the Craftsman tester, it was a POS.
Thanks for tips!

I made me own: all you need is a pipe from a defunct footpump with the valve connector, a T piece of suitable dimensions to fit one of the small coolant pipes and a spare wheel with tyre.
inflate the spare wheel to about 20 psi, connect the T piece with a bit of spare pipe into one of the small coolant pipes (modern ones have littel 1/4" size pipes going to the expansion tank - on a series, you'd probably need an unequal T and put it in the heater pipe.
connect connector to the spare tyre, till the pressure cap blows off on the rad or coolant tank.
If you want to be really cunning, you can blow the tyre to the pressure the cap is meant to blow off at, and that lets you test the cap spring as well.
Sounds ingenious, but why do you need to link it to a tire? Does it leak or something?

you use the tyre to supply pressure. I guess you could use a pump. Pressure loss is generally the problem, though, if you've got to the point of looking for leaks with a pressure tester.
oh, and if anyone's tempted to play... do it with the engine cold.
traced a leak on the TDi which was otherwise invisible by this method.
Oh, ok. I had assumed that there was some volume in the reservoir and hoses that could be used to hold some pressure. After all, if its a huge leak, it would be obvious where its coming from!
Thanks,

well, yeah. But if you want to maintain a pressure of (say) 12 psi in a system that's leaking, you're going to have to keep pumping, whereas connecting it to a spare tyre blown up to 12 psi means that you have a fiar reserve of pressure while you wander around peering at the bits that a re leaking.
Or just pop it into a Serck depot if there is one near you - they pressure test FOC (and found the leaking water pump I had today)...
