Coolant flush with vacuum fill tool

[wrljet]

I'd say go ahead and try it, I have seen people use the squat "pancake" style portable compressors used to run nailers and it worked, it just took a bit longer to pull full vacuum.

Not to suggest the CFM of a small pancake compressor won't run the venturi vacuum

gadget, cause I have no info on the air requirements, but...

Not really a valid comparison. Nailers and impact guns use pressure, not volume.

A tiny compressor can run a nailer or impact type device.

The car should hold 25+ inches of vacuum indefinitely if the system is sealed. We typically let cars sit under vacuum for 15 min. as a final leak test before refilling them.

I had the snap-on from earlier use on domestic cars but Uview looks like a great tool. I guess I need to check the front radiator tubes also since not sure if pulling vacuum past the thermostat. That could explain the system quickly returning to atmosphere. Adapter arrives this weekend.

Adapter did the trick. O-ring was leaking the vacuum. Sucked up the coolant out of 6 gallon water jug I got off amazon. Chilly

I have not seen a 996 thermostat yet. Does it have a bleed hole in it as many other cars do?
