In this video I show you how to vacuum fill your cooling system to eliminate air pockets in the cooling system that can cause overheating problems. To do this I will be using Astro Pneumatic part number 78585. All of these vacuum filling units all work the same way. The tool draws a vacuum on the cooling system removing all air from the cooling system. Next you attach a suction line to draw the antifreeze or coolant into the cooling system when the valve is opened. This procedure will eliminate the need to burp the air from your cooling system. This Astro Pneumatic Master Cooling System Service Kit also has the ability to pressure test your cooling system and some radiator caps.

@not_me_not_you_not730 3 года назад

Depending on the cooling system, and repair made, even though during filling the needle drops to 0 with no more coolant being sucked in, I have found the majority of the time, it is needed to close the fill valve, and open the vacuum valve to further vacuum the system. When you do that, you can hear a difference in airflow (small air pockets being filled with coolant while air is sucked out). You can also feel the air pockets coming through if you put your hand where the tool is hooked to the system. Bottom line, is pulling a vacuum once doesn't cut it on major repairs where lots of coolant is lost, and pockets form in the engine. The venturi effect can only pull so much vacuum on the non collapsible parts of the system, and the most obvious source of vacuum is the flat hoses opening back up. Dont just go one and done. Reapply vacuum for a bit, and fill again. Source: I've done this professionally for many years with several designs of the same type of tool. They all have the same result, and need to be vacuumed down for a second time to be thoroughly filled. It's not the tool. Its the cooling system and repair made to it.

@scottweiss6750 3 года назад

So you're saying that before you introduce any coolant back to the system you pull vacuum, let it sit, then pull vacuum again? Then you introduce the coolant and fill to the vacuum is replaced with fluid and the gauge shows 0?

@not_me_not_you_not730 3 года назад

@@scottweiss6750 pull a second vacuum to get any extra air pockets out that may not have been sucked out on the first go. On the second vacuum, its personal preference to let it sit to verify a sealed system (needle not dropping)

@StilettoSniper 3 года назад

Excellent advice, this is exactly what Uview recommends in their user manual for the AirLift 550000. I have a question for you, since you have run into this firsthand: After the first evacuation and refill, the vehicle cooling system now contains a large amount of coolant. When you attempt to evacuate for a second time to remove any lingering air pockets, how long are you applying the compressed air? Are you still attempting to reach 24 - 26 inHg on the gauge? Since the system is not empty as it was during the first evacuation, I'm concerned about how much coolant would be expelled from the tool during the second evacuation (appreciate if you could share what your experience has been in this area). Thanks in advance for taking the time to respond back.

@not_me_not_you_not730 3 года назад

@@StilettoSniper @StilettoSniper not much coolant is lost during the second vacuum. But it needs to be done to remove any sneaky air pockets. I can't give an accurate range of how much vacuum will be achieved on round 2 because results very greatly between cooling system sizes, repair made, and which systems have a tendency to trap more or less air. Personally I mostly play it by ear and timing. You can hear the change in airflow as an air pocket is expelled through the tool. As more air is displaced by coolant, and there becomes less to vacuum, the airflow changes will become less frequent until they stop completely. At which point, only coolant will be slowly sucked out. Flip the valves, and fill the system the rest of the way. And done. (By the way, there's no reason to worry about coolant being sucked out and lost. Just put the exhaust hose from the tool into an empty coolant jug. It will catch expelled coolant, which can simply be poured into the jug the fill hose is in) EDIT.. I forgot to clarify a little bit as to an example of two different cooling systems, that would most likely have a very different vacuum achieved on round 2, or even round 3 (if need be). Let's say a simple nissan maxima with a v6 vs a nissan armada with rear heat. The maxima by round 2 will most likely hit 15-20 inHg and be good to go at the end of round 2. Whereas the nissan armada, since the rear heater core is elevated higher than the radiator, let's assume that the rear heater core and lines drained out during engine repair. Now there is much more air that needs to be displaced, and replaced by coolant. As well as the fact that in that instance, you also have to battle gravity a little. Roumd 2 in that case will most likely be about 25 inHg. And may take a 3rd or 4th round depending on circumstances. I know it seems excessive, but I have found myself doing 3 and maybe 4 rounds in some cases just for good measure, but that depends on how the previous vacuum process sounded, and frequency of needle drops. (Oil filled guage for much more stable readings while pulling vacuum)

4:05-5:03 WELL SAID . Thorough explanation and presentation of potential issues. 7:50 the extra thorough work to pressure test, even though no leaks were made known while held under vacuum. And the AWESOME (and very plausible) theory 🤓 on why there could potentially be a false sense of a “sealed” “leak-free” system. Could leak later down the road and leave a customer unhappy (stranded if they overheat or even won’t drive with a leak. which we should never fault them for early repairs, or preventative maintenance) and leave a mechanic embarrassed; also maybe scratching our head. *subscribed, and all notifications turned on!

The majority of cooling systems no longer have radiator caps. This tool is essential to modern auto repair and maintenance!! I have one of the top units made by master cool, that I got off the Cornwell truck. I actually they were on back order and I got one used for my birthday! I’m unsure about the cheaper sets, especially where valve components are plastic, but Astro pneumatic is a pretty well-established brand. And all the components are the same selection for the most part. (of unknown varied quality.) For multiple reasons above: Glad you did this review!!

@regkarn1 Месяц назад

You're spot on about the Fit. The heater core is higher than the radiator cap. I don't have a vacuum filler so I had to lift the front end of my kid's car to get most of the air out of the system. I ran the car on ramp stands for about 15 minutes and air bubbles were still coming out. The next time I change the coolant I'm buying a tool like this. Thanks for the video.

@howardshurst1302 2 года назад

Thanks for the video . Having the cooling system empty and being able to perform a vacuum test is great . Before reassembly it is good idea to test for leaks to make sure you have no leaks and you save coolant which is not cheap anymore.

Fill the hose with coolant prior to filling . Otherwise it will suck small amount of air within the hose

@ACitizenOfOurWorld Год назад

Yes, in fact my instruction manual states this:”The Refill Hose must be purged. Slowly open the Coolant Refill Valve so thatthe coolant fills the Refill Hose. Close the Coolant Refill Valve. This process willcause a drop in vacuum.Open Air Inlet valve to re-establish the maximum vacuum level in the Coolingsystem. Close the Air Inlet Valve.Open Coolant Refill Valve slowly. The vehicle coolant system is full when thevacuum gauge reads zero.”

The high brand ones with the same amount and type of components (quality varies) are up to $400. the valves that they come with are the most crucial. If cheap plastic components are being used with hot coolant then for sure they will break down. Especially if you live in a really cold climate. Plastic pieces that get really hot get SO brittle here up the north.

@JrSpitty 2 года назад

Air can get trapped in high spots, not get stuck at the highest spot. Naturally the highest spot is the best because fluid pressure increases the higher up you are, which makes it harder for air pockets to get stuck as fluid try's to force its way into those cavities. There are some vehicles that this is the ONLY method because that difference. There are simply too many high spots in the system for air to get trapped in, and no amount of jacking or elevating the fill spot will purge them.

@bigdfig6083 2 месяца назад

Ya, a little late, but simple answer is no. The coolant, mostly water, is not compressible. Only the air (gas) is and compresses as it is pumped. If there is a leak in the system it will manifest as coolant dripping onto the ground.
