Testing Renix Coolant Pressure Bottle, Adapter?

[knever3]

I have a Stant pressure tester, but don't have the required adapter to go to the traditional radiator cap.  I have seen one FZ25 cap adapter, but at $41 I could almost buy an entire 25 piece kit with a pump.  I am sure to use it on more vehicles in the future, but don't really NEED it at this time.  I would like to pressure my system up to see if I have any leaks since I smell coolant.

 

Please post links.

I know this isnt what you asked for but I was curious if your '87 loses coolant?  I bought my '87 new.  It used coolant every since I bought it.  I took it in several times but finally I gave up and top it off every so often.

I've tested my RENIX stock coolant system recently. I went down to the local auto parts store to rent the complete tool for nothing. 

 

Why don't you do the same?

I spent several years adding coolant to my truck, not knowing where it was going. No signs anywhere of a leak. Finally purchased myself a coolant system pressure tester.  Found out the upper clamp on the lower hose would weep coolant ever so slightly, but only 6-8psi or greater system  pressure. . New clamp and steady coolant levels now.
