I nearly didn't do this while replacing my radiator. My dad happened to call and ask how things were going when he asked if I burped the system. I had no idea what he was talking about and had to look it up. Thank God I did!

I was so upset I thought I blew a gasket after replacing the pump. Glad to learn all this!

Great video thanks. Love the fact that you don't have loud obnoxious music in the background. Camera work, lighting and editing is on the money !

I've watched at least 10 different coolant change or flush videos to find the common steps between each video and I learn something new from each video. The thermostats needs to be installed on with hole at the top for the air to flow through was something I wouldn't have catch. Thank you so much!!

Only video on KZread that actually shows all the different ways to do this! Thank you

1A Auto is the best! These videos are so helpful! I can't even tell you how many repairs I have done using 1A Auto videos, but I just got done changing the water pump, serpentine belt, and pulleys. Thank you!

This guy is great! Thanks for showing how to vacuum a coolant system. I haven't seen it done like that before! These videos just keep getting better! Thank you!😀👍

Lots of great tips that a DIYer would miss, this channel is golden for helping DIYers do a 100% job. Thanks 🙏 it helped me out.

Very well explained, a lot of other demonstrations miss a lot of steps that you covered

The funnel he's using cost around $30. I bought a simpler one at Walmart for $3. It's just a regular funnel but with a wider outlet. It fits snuggly into most radiators, and if it's loose you can just wrap it a little with duct tape. Works real well for this job.

Years ago, my buddy put a new radiator in his 2000 Dodge Ram. An air pocket cost him a $4500 engine. That catastrophe made me gun-shy. This video makes me confident. Thank you.

I was just working on the system. The fluid in the overflow still boils after a water pump and thermostat replacement. Love this channel!!!!

Thanks for showing how to use the vacuum tool. I bought one for my vw 2.5 jetta since my setup just has the reservoir tank.

that was a very well rounded treatment of the subject, covered all the possible situations and solutions, thank you! Some vehicles have the heater core at the highest point in the system and those can prove a little stubborn in ridding air lock. However that is usually achieved with repeated heat up and cool down with circulating coolant. Just be sure to have plenty of reservoir coolant available in the expansion bottle so that as the air is purged there is enough coolant to fill the void.

Thanks for this video..changed out my radiator first and it still was overheating after I filled it up .so I thought well must be the water pump and got another thermostat as well. Changed that and still was overheating..well guess what....I didn't let the air out. Great info and helped a lot..your guys video help me save around 2000 in labor btw..dodge ram 1500 2011..god bless you guys

I really liked this explanation of bleeding the coolant system, especially the part of placing the little hole in the thermostat at the top which promotes air escaping. You guys cover all the issues. I will be watching many more of your videos. Thanks.

those intros are well thought out... i appreciate the effort!! great content

Loved your video. Spoke very clearly, very precise and descriptive. Anyone will be able to follow along.

Wow. Far more information than I expected in this video. All of it valuable. Thank you!

My 97 Accord EX started to overheat when I was waiting to make a Left turn to go inside the mall parking lot, I saw smoke coming out of my hood I looked at the temperature gauge and it was maxed out all the way to the top Red line Hot. I quickly pulled over, parked my car shut the engine off looked underneath my car there was radiator fluid leaking out like a water tap. I had to call my buddy to bring me some radiator fluid and water. It turned out to be a slow leak, I still managed to drive it back home and to work the next day while monitoring the temperature gauge. As I'm halfway through my work shift fluid starts leaking out, I had a bottle of radiator fluid in my car to top up after work I got down to figuring out where the leak was coming from sure enough it was the heater core hose a tight spot to reach. There was a small pin hole inside the hose causing the fluid to leak out, after replacing the hose and topping up on radiator fluid and water it stopped leaking and the temperature gauge is where it should be at Normal.
