Thanks so much for this video! I have a 2013 Altima. I have never performed a coolant flush and replacement before and this video gave me everything I needed. Saved me tons of money and now and have more tools for future work! I was pretty confused about the amounts of coolant concentrate and distilled water that are added to the coolant system and reservoir starting at about 9:10. I kept asking myself why the video wasn't adding fluids at the 56/44 ratio. To anybody who's there with me, it helped me a lot to slow down, and run the numbers myself before following the video (and hey, his numbers are indeed correct!). My math below for anybody who doesn't want to do it: The coolant system capacity is rated at 2 1/8 gal of fluid, including the reservoir. During the initial drain, we got about 5 qt = 1 1/4 gal of fluid, which theoretically leaves 7/8 gal of fluid stuck somewhere in the coolant system after we've tried to drain as much as possible. After we've performed several flushes with distilled water, we can assume that all of that 7/8 gal of fluid in the system is just water. Since the Prestone concentrate is 56/44, we theoretically want to wind up with with our coolant system having 1.19 gallons of coolant concentrate (just short of the 1+1/4 gallons, or 5 qts, the video says should be added) and 0.94 gallons of distilled water (just a bit more than the 7/8 = 0.875 gal that's stuck in the system after the final drain). That's why you add just a little bit of water into the coolant reservoir and then top of the rest of the system with coolant concentrate. If you added 5 qt of a 56/44 mixture to the system which already has a lot of water in it, your coolant would come out very diluted. Maybe to some people this was super obvious and didn't need to be explained, but for me it didn't stick until I sat down and wrote it out.
Great video! For anyone wanting to use the OEM fluid (which is pre-mixed 50/50 - I get it from Z1 Motorsports). You can flush your heating core (which on this vehicle is right in the middle of the firewall), by getting a simple adapter kit, hooking a garden hose to the kit and reversing the flow of the water through the core. Then use the OEM fluid, pour it into the core intake, which should then push out the water from the garden hose, allowing the perfect 50/50 mix coolant to stay in the core. Detach the adapter, reattach the hoses into the core, fill the radiator as shown in this video… voila! That very a simplistic description, but that works. Done it a few times.
Thank you. The heat was on, the temperature knob was turned all the way to heat. And this car was blowing some serious hot air when running it; had to roll the windows down.
Great video. This will save me lots of money. Question: why did you put a Concentrate in the reservoir and a Pre Diluted mix into the radiator? Also, about how many times did you have to flush the radiator with a gallon of water?
I added concentrate to the reservoir, then added water (9:19). I used the same concentrate in the radiator as well. However, there was water already in the system to dilute it to the proper mix. About 7 times.
I have a few questions. When running through the cycle, it runs through the engine and everything correct? My coolant holds 2.25 Gal so when doing a flush does that mean add 2 gallons? Last and not least, can I buy one of those radiator flusher bottles and add distilled water in the first process? Like you I'd like to do atleast 3 flushes in mine. Thank you! Very informative video! I'm always cautious in doing new things especially with my car but It was $145 for a flush. So it seems simple enough process for me.
1) Yes. With the heater on, the coolant circulates throughout the whole system. 2) No, you add approximately what is drained (~5qt at a time). Everything you perform a flush, you are diluting the coolant with distilled water. 3)Possibly. However, I recommend following the directions on the Coolant Cleaners.
A full flush would be required if the vehicle has been neglected for a substantial amount of time or the coolant is contaminated. But if the vehicle is new, a simple change should be sufficient every 60 months.
Have a 2016 Altima 2.5 cvt- Radiator fans won’t turn off- except when car is off. They come on full speed when the cars cool when it’s up to temperature all the heating air conditioning controls off it’s very strange. Maybe you’ve heard of this any thoughts?
If you're filling the system with ~5qt of 50/50 Coolant Mix, it's going to give to a ~21% coolant to water ratio. By the recommended ratio, this is too diluted and may be susceptible to freezing. However, if you're located in a very warm/hot climate (year round), then this may be acceptable.
Step 15 (9:12) we added coolant concentrate and water. And yes, the final refill in the radiator was coolant concentrate only since some of the system contains distilled water.
OK, thank you. One more question....About how many gallons of distilled water does it take to do this? And I'm assuming that when you drain it each time, not everything comes out and what water remains gives you the correct ratio. @@mcgurrentertainment
Yes, you don't want to reuse plastic radiator drain plugs (per the service manual). When I was performing the flush, the OEM plug was starting to have damaged thread; creating a bad seal. When I googled the Nissan Rogue, I found 2 sources for the drain plug (Part Number: 21440-5V000): parts.nissanrva.com/p/89543998/21440-5V000.html www.nissanpartsdeal.com/parts/nissan-cock-water-drai~21440-5v000.html I recommend confirming with the vendor before ordering. Hope this helps.
A few minor reasons. 1. I wanted to provide a coolant that is compatible with a majority of vehicles. Making this video helpful to a wide range of individuals. 2. Prestone is a good name brand, and creating coolant is their specialty. 3. Price and Convenience
This job should take no more than a half hour total. You can literally just take a hose and flush it out. This is 90% unnecessary. It’s completely unnecessary to heat up your engine with water in the system as well.
