not good
This is an impressive package but the components are made so poorly that it shouldn't be sold. No matter how you apply the test adapter to the pump and radiator, it simply doesn't hold...

Comments about Pittsburgh Automotive Radiator Pressure Tester Kit:
I used epoxy to fix all the cracks, but will still never test up to 16 or 17psi without another crack appearing.

Can't even use on a stant tester. All fittings can be used on others but they are also cheap and crack. Terrible product
BOTTOM LINE No, I would not recommend this to a friend

Comments about Pittsburgh Automotive Radiator Pressure Tester Kit:
If you buy this keep your receipt, the pump housing loves to crack and it will bleed pressure through the pump. Otherwise I love the product.

Comments about Pittsburgh Automotive Radiator Pressure Tester Kit:
So far I have found only ONE vehicle that this Radiator Pressure Testing Tool will work with. All others have no adaptor included in the kit to enable me to do a test. I am not talking about exotic cars and trucks in the least. I am talking about one of the Big Three's vehicles ( I work for a municipality) I also own one of this same manufacturers vehicles - a 2013, and it doesn't work on mine either. It was a waste of money!

Bought this to test coolant system on my 97 Corolla. The cap that is supposed to fit the car is too tight to press down. I didn't won't to force it because of risk of breaking radiator neck. Also the instructions are poorly written. Never could determine how/when to use the #14 stainless fastener which is supposed to be used for all adapters and seat accessories for toyota.

Pay more and get a professional set and avoid the headaches and frustration.
