- Check pressure gauge: (1) If the gauge pointer maintain in several minutes, the system is normal to work; (2) if the pointer drops, the system has crack due to pressure damage, you should maintain it and make sure the system can still work after the maintenance.
- After the check, release pressure from decompression valve till the gauge return to zero.

Does work for BMW E46 - hard to figure out from the various descriptions if these things fit these models, but this one does. The pressure pump is awkward, as it really could use a foot to rest it on something when pressurizing the system.

0 stars. First time use the threads on the pump broke. I was tightening it because air was leaking out and couldnt build pressure on radiator. Why would the threads be plastic????? Trash. Out of return window. Waste of money. Throwing it away. Tried using it once before and none pf the adapters fit anyways. Doesn’t function at all.

This is one of the Fastest and easiest ways to find a cooling system leak!I discovered were the leak on my car was in less than 5 minutes after opening the package and hooking up the easy-to-use tool.I've been hunting for that leak for days and carrying around, and using, so much fluid for top ups that I was avoiding driving on the Highways!I should have bought one a long time ago.

The most common American radiator cap adapter they have in the kit is the right height. But they put a metal washer in the middle that is much bigger than the neck opening on radiator. Meaning that the rubber gasket never has a chance to seal against the radiator in order to build pressure. If they cut the diameter of it in half so that it was about the size of a quarter instead of a half a dollar it would be a great kit.

I found a coolant leak on my Camry. Fairly difficult to find with just a naked eye. This product cut my time and expenses in half, at least. By the time that I figure labor costs and diagnosis fees, this little kit has already paid for itself Four times over!

If you have a leaking coolant system on the car, this kit is a must! I had been tracking a leak that was in a weird location and this kit proved that I needed a new radiator. Not just a hose. I also used it again after paying for a new radiator to ensure that nothing else was leaking.

Other than the caps being just a bit touchy this is a great buy for the money. Be carful not to have any sideways pressure against the tester caps or they will leak down and give you the impression that the system is leaking rather than the cap. Otherwise the pump and gauge works perfectly.

This is a great little set that will fit almost any coolant cap. The pump is little bit hard to compress due to the small knob but it makes finding leaks sooo easy. It saved me a lot of time and grief. Also you can’t beat the price for the service you’ll get. I found the sneaky leak in our BMW E60 in no time.

Bought this to test my for a leak in my 1988 iroc and it worked perfect. Saved me a lot of money going to a garage. Easy to use and had the adaptor I needed even though it wasn't listed.
