How to SUPER FLUSH your Cars Cooling System

Learn how to flush your cooling system including the radiator, heater core, and engine block. I go though every step to SUPER FLUSH your cooling system completely. My truck's cooling system was really really bad and it needed a good flush. Now the cooling system is filled with brand new coolant and is clean!

If your system is old or dirty, that dirt could be clogging holes in hoses, seals, and gaskets so take that into consideration when you do this.

It's 3am, I have to be up in 2 hours, I don't have a vehicle, here I am.

Edit: it is November 2022 and I've been performing all my maintenance on my 2016 toyota Rav4 for 3 years now.

It's respectable that Chrisfix, a YouTuber his size, still takes time to read comments and answer questions on old videos.

Took my vw golf to jiffy lube for a “coolant flush” they did a radiator flush and added the universal coolant which mixed with my G13 euro coolant. I thought they would flush the whole system first but I guess not. Technicality eh.. Anyways, so I started doing some research and came across this video. I bought the right coolant for my car along with distilled water and a coolant cleaning conditioner. I super flushed my coolant 5 times until only clean violet/purple coolant was coming out. It takes a lot of time to do this but it’s very satisfying. This might sound cliche but If you want something done the right way you got to do it yourself. Thanks to Chris and the alike to teach us to do it ourselves.

Chris I’ve been a mechanic for 30 years. I just wanna say you do a great job explaining in your videos and you are very thorough in your work. It gives me hope that their are some good young mechanics out there. Keep them coming even though I might know how to do what your explaining I always feel your never to old to learn something.

GM was smart enough to put auto-flush on my coolant system. Every 10-20K miles on my car, a major coolant hose or connector fails draining the coolant automatically to ensure no contaminates can build up. Currently, my car is on the slow-drip flush program. It also attempted to burn the contaminated coolant as well.

Wait until you see how I keep the brake fluid so clear...

The thing I most appreciate about your videos is that you always show how to dispose of chemicals, in this case coolant, but also oils, refrigerant, etc correctly. Youtube is filled with people taking shortcuts; it's so important that we have examples of doing things the right way.

I have been working and customizing my own cars my whole life and I'm now 50 years old showing my kids how to do it. I hate paying someone to do what I can do on my own plus I enjoy it. I love Chris's videos and he is very thourgh and has actually showed me alot of pointers that I haven't ever seen or thought of. I love how much detail you go into and I'm sure it takes you alot of time to video so much detail. Keep it coming Chris Fix you rock and doing a great job. I hope you enjoy making these videos and I'm jealous!!!!

The look on my boyfriend’s face tomorrow when I tell him I’m going to change the coolant will be priceless.

Imagine buying a second hand car from this guy. Would be an absolute minter.

I saw this video when it was released five years ago. Skip to a couple days ago, the plastic quick-disconnect coming off the heater snapped in half, and all my coolant leaked out causing my car to overheat. I managed to replace the part and get everything all connected up, but totally forgot about there being two different types of coolant, and I filled the system up with green coolant instead of the DexCool I was supposed to use, and now I need to flush it. For a moment I thought I'd need to take it to a shop, but then I remembered this video, and having re-watched it, I'm confident I can do it myself. Thanks Chris! Your videos have saved me a couple times when I really needed help.

Your videos are super detailed and easy to follow. Really good job man! One thing that’s worth mentioning is that most engines will have a coolant drain plug on the engine block. This will help speed up the process by completely draining the engine of all the nasty water before beginning your clean water flush. 🙌🏻🙌🏻🙌🏻

I just wished to say how much I appreciate your videos.
When I was in my twenties, I worked on my cars all the time, repairing, maintenance, fixing up an old car etc. I was also into tinkering around the house and workshop. Then life got in the way... divorce... depression... and before you know it, did not do anything for myself. Then one day I realized how much the brain's "creative force"... tinkering, "maker" stuff, repairing, modifying, art etc... all helps to HEAL depression. Where once I was actually afraid to look under the hood in case there was ANYTHING wrong, now (almost 60) I'm determined to not just own my car but "OWN" my car... if you understand my distinction.
I find your videos, and the videos of makers and tinkerers out there, INSPIRING and helpful!
Cheers! :-)

Thank God for YouTube and for people like you who like to educate the rest of us who wanna do it ourselves and save money and make sure it's done right.

[calebdavis]

I'm about to do a complete cooling system overhaul on my 99 Durango. I'm changing out all the hoses as well as the water pump. Radiator is already new. I'm super nervous for some reason, but watching your videos before doing something always makes me feel better. Keep up the good work!

[Dayv]

Your videos have come a long way in 8 years. Definitely refined your presentation technique, and the blue gloves was a great idea to let everyone know they're watching CF and not another guy. Kudos for your success, I'm sure you've helped loads of people fix up their cars over the years.

[manmeandyou]

i don't even have a car but this is so satisfying to watch xD

[residentJokeBiden]

[zachbreece]

Chris thank you so much I blew my heater bypass line yesterday and I swapped out my hoses today and then did my first ever coolant flush. I’ve been watching your videos for years but have only started doing the stuff this year and my car is running/looking amazinf
