I'll have to get something to measure the radiator pressure. I seem to recall you can get a replacement plug thing for the rad cap which can allow a standard hose fitting.
Oh the joys of crappy vehicles.

While that is good for a low cost shop use situations, the chemicals are kind of a blah to deal with. Who knows how to dispose of them or if they are carcinogens? Do the chemicals go stale over time? What happens if the fluid freezes? ect. So I looked for some electronic versions of a combustion sensor, and found a price range that's commonly between a couple hundred dollars, to thousands of dollars. Such an option would be handy for shop use, but I wonder, what happens when people use those liquid head gasket repairs, which may patch a combustion breach for a period of time. It would be handy to have something I can install in the vehicle for a prolonged period of time and sense an intermittent combustion to radiator leak.
The used vehicle I have may or may not have had some liquid head gasket repair added to the coolant. I know it has intermittent overheating issues. I think this kind of tool would allow me to isolate the problem. Does anyone have any thoughts about if such a sensor could play nice or be of any use in this kind of detection?
