Works! Such a simple concept, why aren't more people doing this?

Glad I made the purchase. Easy to use. No more running the engine til hot, waiting hours to cool down to add more coolant, repeat-repeat, until you think you *might* have all the air out. This does it in 20 minutes. The convenience I enjoyed using it only once or twice makes the expense worth it in my opinion. I am currently troubleshooting some issues under my hood, so this is getting used frequently.

The large funnel is made of thick and durable plastic, Lisle did not cheap out, and the bottom spout seats perfectly with the filler hole adapter. This model 24680 has more parts than the previous older model 24610 which sells for a lot more here on Amazon, so DUH, buy this one. Functionality should be the same, except you have more options with the additional angled knuckle joints for difficult applications. I do not have any need for the angle parts, as my radiator filler hole is at the top and level, so I cannot comment on their effectiveness or quality except I will report that they are all made thick so should be durable. I will hold on to them and the assortment of differently sized filler hole adapters, of course, for the day that they become necessary for another vehicle. Great addition to my tool collection.

I purchased this funnel to do a complete air bleed from my cooling system ('04 Pontiac Grand Prix GTP). I had a bit of an issue with the 'threaded adapter" (the black one in the product photo) - the threads didn't quite match the threads on my radiator neck, so it didn't want to thread on straight.

Fix:
Since I couldn't get it threaded enough to make contact with the top of the yellow radiator plug adapter, I had to slide on an additional rubber o-ring (from one of the other adapters) so it would sit a little higher out of the radiator neck, and allow the threaded adapter to make contact with it and keep it snug (and not leak). Other that that, this product worked great.

One word of caution - after your engine has been running for a while at operating temperature, some of the bubbles may not actually be trapped air - it's your coolant boiling a bit. I made the mistake of having a little too much fluid in my funnel when I decided to shut off my engine - because a few seconds later, the fluid started expanding and it overflowed out of the funnel, making quite a mess. Next time, I think I'll keep the engine running, plug the funnel, remove it and the adapters, then cap the radiator (using gloves of course!) - that way any expansion will redirect to the expansion tank, and not out of the top of the funnel.

My 350z has a closed coolant system not like my older GM vehicles where just leaving the radiator cap open would burp the air out
of the cooling system. My car would overheat and I didn't know why until someone told me that I needed to buy this to completely
remove the air out of the coolant system.

How to do it:
From all my reading the best way to tackle this issue is to attach the funnel to your radiator cap opening while cold and fill the funnel about 1/4 up so when system burps fluid falls into they system rather than more air. Let the car idle until normal operating temperature also have your heater set to full hot to allow the fluid in the heater core to flow through also. Mainly look at your needle on the gauge and once its about 1/4 of the way up or
if you have a gauge with numbers and it reaches 160 to 180 you should be good. At this point the vehicles thermostat will open and start
allowing the hotter coolant to start flowing into the radiator and the cooler fluid should start running into the engine block. Bubbles should start
coming out of the funnel this is the air that was trapped in the system coming out. Add coolant to the funnel to keep it at the 1/4 mark so air can't get
back into the system. Also if you have an RPM gauge you can step on the gas pedal and hold the RPM's at 3000 for 10 seconds and then release
for 10 seconds, do this 3 times. Then let the car idle until you don't see to many bubbles coming out and shut down the car. This should take no
longer than 30 minutes then shut down the car. Leave the funnel there for as the car cools they system will still draw fluid from the funnel during
cooling. Check your coolant overflow tank and fill it to the full hot line.

it is pretty handy, except that it seems like the caps are all very tight fitting, even for someone with pretty strong hands. maybe it's just me. also, i was a bit irked when it overflowed from only 1/8 filled while burping a system. i built my own overflow drain for it from a few pipe fittings in case it happens again. otherwise, i love the design concept.

This fit my '03 Wrangler TJ with no leakage and was incredibly helpful in burping the system of air (which the 4.0L engine is notoriously bad about). Plenty of videos online showed just pulling the cap and letting the coolant burp all over the engine bay, but that wastes glycol and makes a mess. With this I topped off the radiator plus about 1/3 of the funnel (see photo), fired up the jeep and let it idle with the heater on max while squeezing hoses. Once I could squeeze every hose without seeing bubbles I revved it up to ~2000 RPM in neutral, let it idle for another 20 minutes, then shut the engine off and let it cool overnight. I came back the next morning and plugged the funnel with the included t-handle "wand", then transferred the coolant left in the funnel into the overflow bottle and capped the radiator. Zero mess.

Definitely makes the job easier and cleaner, but the reason I give it 5 stars is because after using it I am sure there are zero air bubbles lingering in my cooling system.
