    Purge Valve - Cooling System

    Years ago I found a nifty little device to replace the pesky 1/4" NPT HEX head plug used to properly remove all air from our cooling systems during servicing:

    Cooling System Purge Valve...



    I'm curious how many folks bought one and are using it. I'd also(!) like to know who are regularly using the purge valve to safely purge air during hot laps while at operating temps - or really(!) hot.

    Me me me! Installed one of those Swagelock purge valves when the radoator was replaced and also used it for the 90k mile maintenance flush I just did. Loved not fighting with that god forsaken plug. I never burped it after any track days as I didn't feel the need to since my coolant temps were solid and stable. I'll definitely use it again when I remove the upper rad hose to install a 220A alternator and underdrive damper.

    Like some info on that thermal graph deal. How well does it work? And where can one get one if you don't mine or I can just find some.

    Those particular units are 8 level +/-1% and are from Testo. Google temperature measuring strips for other types, styles and applications.

    Are they like a one time use deal or can they cycle within reason?

    I installed one when I replaced the radiator in my magnum about nine thousand miles ago. Glad I did as it made bleeding so much easier.

    I purchased one in 2018, finally got around to putting it in last month when I replaced t-stat. Works great, a little heat around that pesky plug made removal easy.
