Good quality
Arthur –
Great item from AST, same quality but better price then name brand tool truck items.
Jose –
A little more than I wanted to spend but Matco does not provide warranty on their adapters past one year (no moving parts you would think it should be lifetime)this was less than replacing it through the tool truck. Let’s see how long it lasts

The O-ring fell out in a reservoir one day while testing. I didn’t notice this on the pressure tester cap till I tried t pressurize another vehicle and found the o- ring missing. The original car returned with an overheating problem and we found this stuck in the water pump. I wish i returned it within 30 days. This could have been a one off as I have 3 more for (Mercedes, BMW and Honda from AST), but I got written up for this at work and was not happy about it.

Works good on GM vehicles except 2006-2012ish impalas with the 3.9 and 3.5 engines.
Jeff Cholewinski –
Very nice piece from AST. Can verify fits F150 and Super Duty. A few dollars more than truck prices, but all metal. I’m a sucker for all metal
Josh Pierce –
Top notch coolant adapter for pressure testing and filling. Seals everytime no issues.
