How To Vacuum Fill A Coolant System

[@AtoZApplianceRepair]

This is the level of instruction, detail, and skill that makes great content. Thank you!

[@Rythecarguy]

You're very welcome!

[@ahmadghosheh3104]

I have similar kit, more fittings for different cars, I never used the vacuum part, it seemed kinda complicated but it doesn't look like it. Thanks Ry, will give it a try.

[@Rythecarguy]

My pleasure! If you didn't use the vacuum part what did you use it for?

[@ahmadghosheh3104]

@@Rythecarguy My kit has all the adapters for different radiators and a hand pump to put pressure in the system and find leaks. It also has the vacuum part with hoses.I used it to test coolant systems. Bought it couple of years ago when I got a 2003 Camry from the auction with coolant issues, head gasket, and bunch of other problems. It was a project car. Since then I used it when diagnosing coolant leaks. Works pretty good. I have a small hotdog type compressor so I don't get much air flow needed to vacuum the system.

[@Rythecarguy]

@@ahmadghosheh3104 Great point, I used it to test mine not too long ago on the silver Xterra. Unfortunately, thats how I found out that the heater core was bad.

[@Twigz11]

Great timing, I had ordered some coolant and an aluminum heater hose inlet a few days ago with intentions to do this. Just grabbed one of the kits, seems the way to go.

[@Rythecarguy]

Heck yea. Hope it helps.

[@boatsail1]

thanks

[@LittleBJT]

Great explanation and video! Short, and to the point

[@Rythecarguy]

Thanks!

[@domagojgotic4421]

Really cool video and the method is awesome. That would really come in handy for cars whose expansion tank isn't the highest point in the system

[@AdamDitheridge]

Purge the coolant re-fill tube with coolant before opening the valve, for obvious reasons :)

[@rogerdinarte6863]

Well explain video, ive had this tool for years and now i know how to use it because of your video. Thank you, im going to use it haha.

[@JordanPetersonTech]

Awesome video bro. Easy to follow.

[@Rythecarguy]

Thanks man! I appreciate it.

[@Voidhawk001]

Great vid, How much psi do we need on the air compressor for creating a vaccum?

[@michaelg6890]

Super useful video, thank you

[@Rythecarguy]

Glad to help!

[@crvdudecrossoverr6367]

love it! directly to the point and covered the small details to make sure its done correctly. he isnt just a cutie, he also knows his stuff. 🤭

That’s cool👍I just drained my radiator on my Acura ILX, and the spill proof funnel isn’t getting all the air out. I have heat on HI setting, but if I go to 86,85,84, ect… it gets cool, like room temperature? The temp gauge stays normal, the fans come on, but I can’t seem to get the air out completely? One question? Your system must be empty, before you put a vacuum on it, and can you go through the radiator cap, instead of the overflow tank? Thanks

[@robertotr]

What's the air plug gauge? I believe I need to buy an adapter to my compressor, but I don't know the gauge. Could you please tell me? Thanks.

[@XtremeBUZZ]

Keep up the great content Ry!

[@Rythecarguy]

Thanks man!! 💪🏻💪🏻

[@Brian_L_5168]

Great explanation & presentation..! As of today, your M31 coolant refill set is still working fine? I am thinking about buying so trying to know its reliability. Many thanks !

[@EDUCARPUEBLA]

Do you drain old antifreeze in the traditional way?

[@Rythecarguy]

Naw, there was still some in the block. Just the rad and expansion tank

[@smokey2much420]

What size air compressor are you using? Does it matter or would the size just determine how fast the vacuum is created?

[@fowvee]

My service manuals states to use an air source capable of a constant 80 - 120 PSI.

[@Mark-um3hm]

Hey Ry, quick question? I’m going to do this through the radiator cap, and I have a hose, on the neck just below the cap. Do I need to pinch the hose, leading to the overflow tank, to create a good vacuum? Then just fill it manually when I’m done? Thanks

[@hugba]

Hey doggy. Great vid. Will this tool work if the coolant system is like 95% full? Or does it have to be empty?

[@Rythecarguy]

Not to fill but probably just fine to burp/bleed it

[@joshuawalters7377]

If i just drain the radiator or if I drain the radiator and engine block…is the vacuum fill the same?

[@anoldfriend3901]

How do we do this on an 2007 Titan if we didn’t drain the whole system? Also I noticed in the service manual it says to do it from the radiator and place an non venting cap on the reservoir. Can we still use this vacuum tool if we didn’t completely drain all the coolant? Meaning we only drain from the radiator.

[@SaycoPworrell]

You gotta have a vacuum in the coolant system. So when you start pulling vacuum, that remainder amount will be sucked out.

[@johnnywalker4409]

This just answered my question I have coolant still in the system wondered if it would stay

[@CJ.A-C]

ditto to man before. Just bought a new one from Vevor, which has every application going. Bought it from eBay roughly £60. Great video, very well explained.

[@CsillaM.Fisher]

Do you not need to somehow prime the fill line so as to not introduce air when start filling up?

[@squidgypants722]

I'm trying to work that one out aswell. Seems like as soon as you open the valve it introduces an air pocket. 🤔

[@MrShorty2583]

Can you use this for the radiator as well or is it just for the reservoir or does it even matter?

[@Rythecarguy]

Does not matter.

[@fredericomacabu2618]

You forgot to mention the PSI on the air compressor, how many PSI I need from the air compressor to create a vaccum , for mini-van 2013 town and country ?

[@homewrecker44]

Instead of removing the reservoir were you not able to connect directly to the Rad with a Cap Adapter? Unless this vehicle has no filler cap at the Rad and you have to use the reservoir.

[@datboi8140]

Might be dumb but doesn't the thermostat open with pressure created from the coolant heating up? So you'd have to remove the thermostat?

[@rcnewcomer7304]

Thermostat opening by temperature, not by pressure.

[@Idoall.myownstunts]

​@@rcnewcomer7304 Surely then the tool can't refill the system with the thermostat closed?

[@Emiougus]

@@Idoall.myownstuntsthermostat allows flow around the system, filling it you’re putting coolant through both ends so they meet up at both sides of the thermostat

[@Randy-e7x]

Great video! Thanks!

[@Rythecarguy]

Glad you liked it!

[@jimd3643]

Does the coolant system have to be completely empty?

[@isaachorton51]

Someone put an aftermarket reservoir on my car it wouldn’t fit so I put it on the radiator directly it works vacuums it but when I close it off it sounds like it’s gargling in my reservoir or something and the pressure is escaping do you have any recommendations?

[@Rythecarguy]

You’re pressure relief valve is probably opening. You need to block it off like i did in the video. Stick your finger over it and see if the gurgling stops.

[@vantsen-e]

can i do it when there is coolant all ready in ?

[@msburrage74]

So I have a question. I just did this same system but when I was putting the coolant back in it dropped to 0 really fast, like a few seconds and even though the coolant initially went thru the tube the level on the container I had the coolant in didn’t move. I drained the radiator also and got right at a half of a gallon out. So after I took the device off I had to pour that half gallon back into my radiator. So what did I do wrong and do I need to do it again? Seems like my wrangler is still running hot from time to time still

[@robertotr]

Probably it's a leak on the hose, maybe the connection. So when you open the valve, it sucks the coolant and some air. Put some withe tape between the connection that will solve the leaking issue.

[@Tom-q9z5s]

What about air in the heater core...how does it pull this out without the valve open?

[@Rythecarguy]

Pull what out?

[@iulianc9037]

It has only one valve. The air is extracted on the return. Some cars don't even have a valve for the heater radiator.😂

[@PNH-sf4jz]

Also remember to fully open the cabin heater switch inside the car. This will ensure that the heater core is included in the filling process.

[@intercomking4188]

Such a great video,

[@Rythecarguy]

Wow, thanks. 😊

[@johnnywalker4409]

Young Man, does the coolant system have to be empty before doing a vacuum refill? I only removed an upper hose so it may still be half full

[@Rythecarguy]

No it does not. I would still use it if I only did a partial drain

[@johnnywalker4409]

@Rythecarguy did it and worked fine, Thank You

[@BoostedMonkey4g63]

@@johnnywalker4409have you tried to empty your cooling system with this as well? To me looks like you can actually empty your cooling system completely.

[@hjfcoco]

What if the system is half filled with anti freeze, will this still work? Or the system must be empty?

[@Rythecarguy]

You l can use it with a half full system!

[@hjfcoco]

@@Rythecarguy awesome thank you!!

[@markc7889]

How did get the old coolant out?

[@Rythecarguy]

Drained it from the radiator and block. This was an engine swap.

[@gowenrv3762]

Very good.... 😀

[@Rythecarguy]

Thank you.

[@paulchristian4459]

What if you run out of vacuum before completing fill

[@Rythecarguy]

That's fine, just restart

[@davidb649]

Will portable tire compressor kit work to create enough vacuum? Or Without that T CONNECTOR is it possible to directly connect a hand vacuum pump to create vacuum?

[@Logan-dt7ck]

Can the system be empty for this ??

[@Rythecarguy]

Yes, in fact that's when it works the best

[@boatsail1]

why not use the radiator cap?

[@myemohh8753]

You can use either

[@johnsilva8216]

Does system need to be empty?

[@Rythecarguy]

Nope

[@joebovovitch7803]

Is that 55psi?

[@Rythecarguy]

No

[@Rythecarguy]

No
