How To Service the Coolant System in Your Car or Truck! How to Replace or Flush Antifreeze Yourself!

Is it time to service, replace, or flush the coolant in your car or truck? In this video, Andy shows you how to drain and refill the coolant in your car or truck, and gives you tips, and details you won't want to miss! Coolant, or antifreeze, is an important element of a healthy and efficient engine. Old coolant can get sludgy, and clog coolant passages in the engine block, heater core, thermostat and radiator. Worn or weakened antifreeze will lose low temperature protection. Protect your car or truck by replacing or flushing the coolant at the interval specified in your vehicle's manual, or when inspection shows signs of wear!

Hello sir, thank you for the video and all the information. I noticed many videos over internet talking about flushing but removing only water from the radiator... so i want to say you are the only one who explained that water remains in the bloc since the thermostat is closed (cold engine).

@5:33 I would also turn the heat on inside the car to run some of the new coolant through the heater core.

You didn't talk about burping the system. Or what to do if you trap air in the system.👌

I've used a shop vacuum to suck more coolant out of the engine block, works great, just disconnect both the upper and lower hoses to get the most out.

How do you know when the coolant is filled at the right level?

[jasonnellis]

Is it good use upgrade antifreeze and coolant additives

I have a 2019 nissan frontier truck SL 6 cylinder 4wd can I do the same way as well?

Never use the plastic tap to drain the rad if it cracks when turning then it's going to be a bad day.

What is the squealing noise after changing the antifreeze in my car

[thusarapriyaperera]

Hi! Does it a coolant system or otherwise a cooling system? Please, be kind enough to explain it to me. Thank you so much.

Link to your fluid extraction pump in description would be a bonus.
Good video 👍

Why can’t you use something like prestone all vehicle coolant? Many makers not just Prestone

[bettyblue]

My Audi used to run with red coolant but I found that there are some coolants that say are compatible with all vehicles and supposedly better- I believe it's referred to as HOAT. What's your take on that?
The coolant I used: Prestone All Vehicles - 10yr/300k mi

Should have done a more indepth video about the flushing of the system

Hi Andy,

What are the consequences of having an overfilled degas bottle?

I own a fiesta, and I mistakenly filled the degas bottle to the max line while the engine was cold.

This bottle is, obviously pressurized and the level was about a quarter of an inch above the max line at normal operating temperature.

Would this oversight cause engine damage?

It looks a bit like Laurence Fishburne's white one.

[SamLopez]

Just wanted to say for others watching who don't know, in addition to recycling centers taking the used coolant, most big box auto parts stores also take fluids like this!

My car is making a squealing noise after the antifreeze been changed

I have a 97 Chevy s10 4cyl 5 spd, and I want to put a automatic transmission in it but don’t know what one to get.
