Without a service record, assume 60k-100k miles on a car built year 2000 or newer.

I added a prestone 50 50 in my tacoma 2018 the color of the coolant was pink and Preston is green is that compatible or I need to flush the coolant?

jose perez Check the manual for your truck

It’s hard to say what they changed it and if it can be mixed, but the most sure way is to drain it all and replace it with all the same stuff. Especially as it breaks down over time with heat.

@@dannyjohnsonsgarage- Thanks for the quick reply! Ford's owners manual says first service at 100k but then 50k after that. I'm just shy of 100k and was going to do a drain and refill with PEAK Orange. During the drain, I'm going to check the fluid to make sure it doesn't look too bad.....already tested as still good. SO I'm thinking drain and refill should be OK, no flush needed. And then maybe do the same every 30k or so. Thoughts?

You’ll have to go into an auto parts store and see what they have in their system for what they carry. If I give you an option it would probably be a US one

@@dannyjohnsonsgarage Thank you!

@@dannyjohnsonsgarage I've found here in Greece a coolant named "COMMA Xsteam G05". It mentions it is approved by Chrysler (MS-9769). Could you please tell me if it is suitable for my Dodge Caliber 1.8 2009? Should I be careful of its colour? Thank you very much!

prestone can be mix with anything due to its unique formula

Prestone is OAT

Prestone 50/50 would be fine. It does already have distilled water, so just keep in mind you’re paying them for the weight of the water and will save some money if you buy the concentrate and then just pour in the distilled water as you pour it in (you don’t need to mix it before hand, it will do that over time).

@@dannyjohnsonsgarage I recently completely flushed my cooling system and replaced the coolant. I did a very thorough flush using a radiator flush kit, distilled water and flushing several times. I removed my thermostat, put the heater on high and drained my reservoir tank. I had completely clear water draining out prior to re-adding coolant. I added 2 jugs of the new coolant which was prestone concentrate. The jugs were 3.78L each for a total of 7.5L of concentrate added. The capacity of my cooling system is 15.3L so I figured that using 7.5L of coolant would give me a 50/50 mix (or very close) which is what is recommended. After doing this I went to a local oil change shop and asked them to test the ratio using there ANTIFREEZE COOLANT TESTER. They sucked up a sample and said it was good for about -35 C. They explained that this was a little warmer than they usually go (they like to see -45 to -50) but because I live in a place which rarely goes below zero and never below -10 then it should be fine. I did not have them test the acid/ph level at this time. 2 weeks later (today) I went for an oil change and they tested my coolant with a little strip of paper. My PH level was 5.5 which is low (should be a min of 7 and ideally between 9-10). The test was conducted right in front of me so am not concerned about them misleading me. My question is (which they weren't able to answer) if I drain out some of my coolant and add some more of the concentrate (making my ratio stronger) will that increase my PH level? I've tried to look on google but can't find anything specific. Is my PH level low because my ratio of water is on the high side, or does the ratio of coolant to water have nothing to do with the PH level.... thanks.. Here is a link to a video of my flush... if you watch the first 3 mins you'll see the original coolant... it looks orange which everyone says is CHRYSLER HOAT... but my owners manual says its OAT and warns specifically not to use HOAT. Some people tell me that the HOAT is also called G-05... while others say G-05 is OAT? I would appreciate your opinion on it if you have the time... as you'll see in the video my original coolant was very dirty looking and gunky... not sure what to do now to bring my PH level up to normal. kzfaq.info/get/bejne/m5aPebOq3Jumo5c.html

@@jonh2408 You are way overthinking it dude. My 21 years of cars I have never had to break it down like that. Just add coolant to your water. Try for 50/50 but if not perfect it works.

If you clean all of out you should be fine using prestone all makes all models all colors. It’s only bad if you mix it

@@dannyjohnsonsgarage not prestone. I suggested asian zerex by valvoline. Hoat type

Every car is designed by a different team of people. Those engineers all look for the best stuff they can use in their time-period. So long as it’s commercially viable. So really the only way to know is to read the owners manual, then check out owners-clubs/forums to see what they think is best from ownership experience. My entire brand of car (Subaru) wasn’t mentioned. It uses a purple coolant, which he did mention is commonly found in Asian manufacturers. To be honest I’m surprised at how much useful background information I got out of this video, despite no specific advice for my car, definitely worth it :)

No they aren’t all the same. Got to see what they’re made with.

Basically Taylan, you‘re either gonna have to believe some dude on the internet, or become the dude who tells people what happened to them

Silicates, which makes one think of glass and silicone epoxy, are very inert, thats really it’s main feature, even when used in semiconductors it’s an inert background on which more interesting ions are inserted. If you wanted hard there are better ceramics, if you want lubricating there are better oils/liquids, but if you don’t want stuff to grow on it silicon-something is an inexpensive choice. So I can’t say what the Ethylene Glycol will do over time, but I can’t imagine the addition of silicone will cause it to change overtime. It’s gonna change during the addition but not over time. There are some radiator-sealers/repair additives that use silicon to plug up holes, and they are supposed to be flushed out after a certain number of minutes of being added to the system. It’s usually a small bottle and you add it to the coolant system after doing lots of pure water flushing, adding only water, letting the car get up to temp, then cool enough to add sealer, then run for 8 minutes, then dump it all and add fresh coolant. Perhaps if that stuff is used and never removed the loop will get high resistance to flow over time, like it was gumming up.

You’re right

Different colors may not be compatible with each-other and cause the coolant to break down and not lubricate or cool properly. It’s best to keep the same or drain it all and start over

If this on a boat? It’s water system is pulling from the water. If not, Remove all fluid, fill with distilled water, run for a few minutes and replace several times until clean

My 2005 impalas is mud!! Why?

@@airexaxe7554 probably has oil mixing in the coolant from a bad transmission or oil cooler gasket or maybe even losing a head gasket

@@dannyjohnsonsgarage Crazy! Thank you very much for another way through this

I’m sure that’s fine. You can also put distilled water in and it dilutes it but mixes as well so other coolant should be fine

@Danny Johnson’s Garage it's been okay since. From my research and phone call to Napa, it seems that the important factor was that I had yellow (low silicate) HOAT antifreeze in the truck. Had I had orange (silicate-free) HOAT in the truck and mixed in the bright green (high silicate) IAT, there may have been a mixing issue.

You’ll want to also burp the system by finding a bleed valve or a high point. You’ll want to do it when the car is cool so you don’t get burned. The idea is to get all the air out of the system kzfaq.info/get/bejne/rMqZeN2Szaepkmw.html

Ok .There was no question. I'm looking for answers elsewhere Thank you

My advice is to not mix colors. Drain the entire system to use a different color.

g13 is later, so I think you can add g13 to existing g12, but the other way around is not recommended.

You may or may not depending on which additives used, so the color is a warning. Some say mix any

You can. I mixed glycol coolants whole life without any problems... Color is nothing, companies use different colors for their coolants.

Orange

It could depend, you would want to see which chemicals are in each

I would do one or the other. Mixing can cause it to break down and not cool and lubricate properly unless it says it’s safe to mix

For what it’s worth, although the supercooling is blue you‘re advised to use purple coolant if you just get a generic. Normally blue coolant is not for Aluminium engineblocks. Im sure you knew this, but it’s a mistake i made a long time ago and i can’t forgive myself lol

@@John-rw9bv it’s genuine coolant from Subaru & it’s blue

@@l... I know dude, but it’s only blue because it’s „Subaru World Rally Championship“ blue a.k.a „Subaru Blue“ - but if it was colored like a generic coolant, I.e for any EJ/EG/EE/EZ/FA Subaru engine, you’ll want to use purple if you can’t get Subaru own-brand Super Coolant.

@@John-rw9bv thank you

It will be hard to say by each manufacturer, so the best advise is to start fresh with new coolant for the system or purchase exactly what’s is it now to add

Some companies claim their fluids can be mixed with any make, model, or color. It may be okay but the color will look weird when you see it mixed

Who are you

Who are you?

Who are you even

So you listed a whole host of parts failed in your cooling system and you still think mixing coolant is fine 😅 you must be a clown lmfao

It depends on which red and yellow they actually are, so you’re best off draining the system entirely to fill it with only one. Do not mix is the best advice

I would drain all of it and run only one color

It has chemicals and deposits that will form rust and will corrode

Prestone brand says to use distilled on their instructions

The coolant includes corrosion inhibitors. You aren't using distilled to avoid corrosion. You're doing it to avoid mineral deposits. Filtered tap water will still have a high proportion of calcium, sodium, etc in your water.

@@dannyjohnsonsgarage I've never read the back of the Prestone brand. But some don't say anything about what kind of water and some say use de-ionized water.

@@lmaoroflcopter Good to know they have corrosion inhibitors. Unfortunately they don't mention it though. Still, I'd rather go with filtered drinking water rather than distilled water. I wouldn't consider filtered tap water any useful unless it goes through a really good filtration system. Which is what I would consider drinking water. Still, there will be some minerals in the water.

@@thomaswills2301 distilled water would be purer than your mechanically filtered water. Deionized water is broadly equivalent to distilled, it has all the mineral ions extracted from it, sometimes via distillation even. Drinking distilled or deionized water would be ill advised, unless you like electrolytes (those pesky minerals that screw up cooling systems) that would serve you better in your body, in your urine.

The color matter because it’s how it differentiates which coolant with what chemicals and lubricants it has. You don’t want to mix them as the video talks about

Nowadays, I'm hearing of oil-based coolant. What is this? One source on the Internet says the coolant is oil-based as long as glycol is included.

You could be right about the colors as other sources on KZfaq talks about dye as per manufacturer specification. The important thing is to know the coolant ingredients.

Watch the video buddy

Not funny.
