The GoWesty Cooling System Pressurization Tool offers a straightforward, effective way to remove trapped air from your cooling system—especially from the radiator.

In a Vanagon, the top of the radiator is higher than the coolant bottle in the rear (where you add coolant). When filling an empty system, whatever air is in the radiator (above the level of the top of the coolant bottle) stays in the radiator... because water doesn't flow uphill. Also, any air remaining in the system in the form of bubbles will accumulate in the radiator. Contrary to popular belief, simply lifting the front of the vehicle with a jack does not help. In fact, one could argue that it actually exacerbates the problem!

The more air in the radiator, the less effective it is at keeping your engine cool. It is like having a small radiator that looks big. Failing to get all the air out of the radiator can cause all sorts of phantom cooling system performance issues, and some that are not so phantom, like a complete melt-down of your engine.

This GoWesty tool does exactly the same thing as the OEM tool shown in the Bentley Repair Manual on page 19.17 (part number VW1274 or VAG1274B). Our tool may not be as robust, but unless you are a professional mechanic needing daily use, this one will do the trick for a lot less money!

Kit includes:
• Hand pump with built-in pressure gauge
• Rubber valve stem to adapt the Schrader-valve end of the pump hose to the nipple on the coolant bottle cap
• Detailed instructions for checking cap, testing for leaks, and thorough bleeding of the cooling system

Pro tips:
• This tool is designed primarily as a cost-effective solution for bleeding air from the cooling system
• The included gauge is for reference only and is accurate to within ±3 psi.
• Do not exceed 17 psi as indicated on the gauge.
• Not recommended for testing the pressure release threshold of coolant caps

Super easy to use and takes the guess-work out of getting even pressure on the grounds
Size: 58.3mm, Color: Black, Size: 58.3mm, Color: Black
I have been using a hand tamper for many years and have a good idea of the pressure I am applying to the grounds in the portafilter. I honestly considered spring tampers to be a bit silly. But this tamper really does take the guess-work out of pressing the coffee grounds. The shroud helps guide the press so that pressure is applied even and flat across the surface. With the manual tamper, there will be some play when pressing, or some unevenness in pressure. This is especially true when cranking out many espressos during a breakfast party with friends. Having the spring tamper makes quick work of turning out a lot of coffees with consistency. There are no instructions for taking this tamper apart to clean inside, and you may not really need to do that very often. After each use, just pull back the shroud (the black piece that moves up and down) and wipe off the tamper (the shiny steel part). This will help prevent grounds from working their way inside. If you do want to take it apart, it’s easy. Pull back the shroud and unscrew the tamper. It will come apart into three pieces. Wipe the pieces off and reassemble. Super quick and easy. This tamper is very heavy. My scale shows 656 g (about a pound and a half). It fits the portafilter exactly, with no slop. Just place on top of grounds and press!. Don’t even worry about pressure, just push down all the way. Overall I had fun using this tamper versus my manual one. And since I make myself a cappuccino very early in the morning, I don’t have to be very awake to get a good pack on the grounds and get my coffee fast!

Quality and Function
Looks like a silly little thing, I am not a coffee enthusiast. But it does exactly what it is supposed to do and with high quality. The device (a stretch to call it that) is made of sturdy materials including the needles. They give you two different thicknesses of needles, one for expressi (0.3) and one set for coffee grinds (0.4). Each comes wth some spares. The stand is well designed and keeps grinds from spreading all over. It is very elegant design. I use this with a dosing funnel on my portafilter. Not the cheapest one could buy but well worth the money.

Perfect WDT tool
Best WDT I’ve found. Love that it includes 0.3mm needles (as I’ve found that 0.4mm needles push the grounds around too much), and the stand is very clever. It knocks off the residual grounds on the needles and is easy to use. As far as WDT tools go, I can’t imagine anything better.
