I think I got a 30 psi water pressure gauge at Home Depot. Check it out. Should be a lot cheaper for a temporary solution.

This cooling system discussion has got me thinking about adding a temporary (before engine monitor) coolant pressure gauge. What would be the best way to install one of these. I think I have a couple of 1/8 NPT holes in the coolant system currently stopped up by unused stock sensors. What would be a suitable (cheap) gauge? Coolant pressure gauges dont seem to be very common in autos. Would an oil pressure gauge do the job OK.

Any thoughts?
