BLUF- at a Insider Track of $64.99- well worth having
Looking to see if a 2012 MB S550 might have a coolant leak. Took out my never used Mityvac MV4560 and quickly discovered none of the four adapters work on this S550.
Went to Amazon, found an Astro Tools 78585 for $225, three days for delivery. Thought to try Harbor Freight. Harbor Freight has a few test kits. This Pittsburgh kit is $95 USD. Through April Insider Trac price of $65 USD. HF states this kit is comparable to the Astro Tools 78585
Came home and tried the adapters, none fit. Taking a closer look, this Pittsburgh kit has a universal adapter, and it did fit.
The Mityvac have to give a thumbs down when directly compared to the Pittsburgh.
If you have a current or future need for a Radiator Pressure Test Kit, and you are a Insider Track member, might be a good opportunity to get it.
