BT-500 Head Gasket Combustion Leak Test Kit - Made in USA

Block tester is Straight to the point, works great. Save me money time and guess work. My coolant kept rising during the test, so I let the steam in and fluid turned green. Suggest it’s a smaller gasket leak. So I’m removing the blocks to have them checked and resurfaced, and install a new gasket kit.

Worked as it should. Made me sad and everything. It confirm the problem I didn’t want to believe I had. Great tool

2002 Dodge Dakota. Worked quick. 💯 recommend. Simple easy to do.

Simple product to use. Fill the line with the provided solution and put into the radiator cap. If it stays blue, you're good to go! Otherwise kiss your headgasket goodbye and prep for a long road ahead. Provided accurate results for my Toyota Celica. It costs a little more than other kits but I can rest assured and confident with the results.

Used this test kit to see if I had engine gases in my coolant which would indicate a possible cracked block or blown head gasket. The test did not reveal any mix, which was good. I still have plenty of the liquid left and you can buy just the replacement liquid at the autoparts store. I'm sure I will be using this kit on other vehicles in the future. Just to make sure the test kit was working properly, I put the tester near my exhaust pipe and it did turn yellow like it was supposed to.

Good news it works. Bad news I need a head gasket.

I suspected that I had a head gasket leak on my 2004.5 LLY Duramax but I needed to be sure, so I bought this BT-500 Head Gasket Combustion Leak Test Kit. It was very easy to use; on a COLD engine, just put the tester on the overflow/coolant fill reservoir snuggly where the reservoir cap goes, add the testing fluid, start the engine and see what the results are. I saw the testing fluid soon start to bubble. Well, that meant that I had air coming in to my coolant, and since it was running, it had to be exhaust air. After running the engine to normal operating temperature, give the suction bulb some squeezes. The blue test fluid turned to a yellowish color, thus indicating that I have a blown head gasket, and/or a cracked head, and/or pulled block bolts or studs, and/or warped sealing surfaces. With any of these potential problems, I'm looking at thousands of dollars in parts and labor. A head gasket job alone is going to cost me $4,500 to $6,000. This tester helped me to easily narrow down what was going on with my engine, and was worth the price because of that.

High quality construction. Arrived quickly on Prime. BACKGROUND I used it to confirm (?) the Honda dealer's diagnosis of "coolant was two quarts low -- seeing bubbles in the radiator -- don't drive it -- must diagnose further." After they saw bubbles, they said the opened up the engine and gave it a leakdown test. All cylinders less than 3%. Then they said they needed to do a "five-gas" test, but didn't have time that evening. They wanted to keep it overnight and do more work on it, but that didn't work for our schedule. I kind of wondered why they didn't do that ten minute long "five-gas" test first before spending an hour tearing into the engine. And I wondered why they didn't just spend the five minutes it takes to use one of these testers. The story was a little fishy, or maybe they were just clumsy and less than highly skilled. Anyway, I didn't trust them 100% at that point, so I needed a second opinion. ENTER THE BLOCK TESTER TOOL Used my tester. Lots of YouTube videos available if you're not familiar. They basically follow the proper directions on the card. Lower the radiator level by 2-3 inches with a turkey baster. Fill the tester. Place tester tightly over the radiator opening and start working the bulb to draw the gases through it for ONE MINUTE. 1) I ran the engine warm. Didn't see bubbles. 2) I took it on the interstate for a while. Didn't see any bubbles. 3) I tried it from dead-cold overnight. Still didn't see any of the bubbles mentioned by the dealer. After each visual test I ran the Block Tester with fresh fluid. Pretty much the fluid stayed imperial royal blue. Fresh fluid for each test. After one of the tests just for fun, I waved it in the exhaust tailpipe plume -- instant translucent hot chrome yellow. So the fluid works, but it just didn't find any combustion gases in the radiator. Also, after one of the tests I kept vigorously pumping for at least another five minutes and it went slightly off of the deep imperial royal blue (almost faintly indigo) toward being still strongly blue but having the slightest hint of aqua. I had some concern. But then I also tested with fresh fluid out in the clean air, and it took again about five minutes of vigorous (spastic?) pumping go get that slightest hint of aqua. Conclusion here, again, is there there were no combustion gases present in the coolant system. I wonder what the Honda mechanic saw? CONCLUSION This tester is awesome. Super easy to use. I would recommend it to friend.

Worked exactly as expected. well worth the money. Diagnosed head gasket failure. 100% would recommend over cheaper alternatives

Fyllde sin funktion, helt ok.

You definitely need to reduce the coolant in your radiator or tank as it will suck up fluid once the car is started and the cooling system starts to flow if it is at normal to high levels. Test is very simple to run and gives very quick results.
