Hi Eric I’m doing the same thing you’re doing but instead of using distilled water, is it OK if I can use well pump water? I want to hear from your response ASAP.

[@sherrokinchen5253]

Hi Eric I bought the same antifreeze+coolant but it has water 50/50 is that OK?

yes that's fine you dont want to use tap water because it has minerals that can eat up the inside of the engine and can cause rust

To everyone saying he used the wrong coolant, Peak Long Life is not the old IAT silicated green, it's a modern OAT coolant and it's perfectly fine to use in this vehicle. It's chemical composition is exactly the same as Dexcool and I've used this and other universal OAT coolants in dozens of different vehicles over hundreds of thousands of miles with no issues whatsoever.

05 Silverado. Drained/refilled twice in 15 years with Dexcool. Never changed a hose, water pump, or anything in the cooling system. About to do it again in a few weeks since it's been 5 years since the last drain/refill. Nothing wrong with Dexcool in these trucks due to the dry intake. If you have a V6 that has a wet intake, I could understand the concern since the Dexcool eroded the intake gaskets and caused a bunch of issues with those model engines.

I would recommend removing the thermostat when flushing out the old coolant since you can then do a number of good flushes without getting the engine too hot. You don't want to refill a hot engine with a cold liquid, a friend of mine cracked his cylinder head doing just that.

Good video man. I just did this process today. One thing you should consider is you never get all the water out of the system after a flush. When you drain your final flush there is a considerable amount of water left in the lines and heater cores and the block and heads etc... You should get a coolant tester and test your finished product because when you figure in all that water and add 50/50 to it you are not left with a final 50 50 mixture. More like 75water/25 coolant. Also i used only distilled water. I never hook a hose to my cooling system...Food for thought

[@followerofchrist1961]

Could you just start it with the hose off to get the rest of everything out?

[@tonylopez9936]

To be sure the fluid is out of the block it is advisable to remove the block drain plugs. There is one on each side of the V8.

[@tonylopez9936]

@@followerofchrist1961 On these engines the thermostat will be closed as the vehicle is not at operating temp. Unless you go through the added step of removing the thermostat you will still have fluid trapped in the block. The thermostat will allow a miniscule amount of fluid pass through but not enough to thoroughly drain the block. I let mine drain overnight just to see & then removed the block drain plugs. Yup, more fluid came out.

1 clear water flush will get you to 99% free of the original charge of red 50-50. 4 X flush is unnecessary. Modern coolants have rust inhibitors and additives to inhibit mineral crystallization, so it is perfectly fine to flush the system with tap water.

You're not supposed to RUN it with straight tap if you somewhere warm enough that let's you get away with it, a flush isn't going to give your water jackets and thermostat enough time and heat to strip the calcium out of the water and mess up your block. I think my favorite thing I've seen is watching a guy pull all the water hoses completely and run a garden hose to the radiator, heater core, and block individually and watched it pump out all the gross crap that doesn't come out in a regular flush.

[@MyT2000]

This truck is going to hold 16 quarts. That’s 2 jugs of concentrated coolant and 2 jugs of distilled water. 😂 just pour a jug of water and a jug of coolant and it will mix on its own thanks to the water pump 😂

[@mikec.6763]

Everything on my GMC says use Dex, I don't know for sure, so I will stay with Dex but Green coolant is a different chemical mixture than Dex. May not be the best thing to do for your engine. You should consult a reliable mechanic and get their opinion. The outcome may not be the best changing from Red/Orange to Green for your truck's internals!!

[@alectownsend1063]

Yeah me aswell iv always heard even from school that switching up the different color coolants they have the different chemicals sorry for not remember but I think it’s the ethylene glycol acts differently to the plastics vs propylene in the specific systems, again no experience in the manner just what iv been thought through school so I have steered away from the swap

[@ghostrider-gm2wg]

Ive had the original dexcool in my 07 gmc sierra since i bought it in October of 06. Thats 14 years. Still runs as cool as it did when it was brand new. Gm changed the chemicals on dexcool in 04 I believe. Doesn't ruin the gaskets no more. As long as you don't contaminate it with another coolant, it works like it supposed to. But if you mix another type of coolant by accident you need to flush the system immediately.

[@alecsanderfuentes3913]

Mixing coolant doesn’t do shit

[@tonylopez9936]

@@alecsanderfuentes3913 Well, actually it does. You can not turn a 2 year coolant into a 5 year coolant. Add a 2 year coolant to a 5 year coolant and you dilute the 5 year coolant. So that proves that adding chemicals has a reaction period. I am told that the newer coolants don't react as the older formulas that turned into a gel & clogged radiators, etc... And it was already mentioned that the red used to affect the gaskets on the v6. You can take a chance with your truck but my pockets aren't that deep. I think Ghostrider has a more salient sugestion.

a good reason to switch from dex is because it becomes sludgy and corrosive to gaskets after ~6 years. gm lost a lawsuit over it. its perfectly safe to switch but only with an extensive flush, but mix dex with green and your gonna have a bad time

[@inhocsigno9151]

When you drained the straight water out, some straight water remains behind. A final fill always add straight concentrate antifreeze up to 50% of system capacity. So when it mixes with the water, it ends up being 50/50. If you fill with 50/50 you may end up with 30/70. Test your final xix with an antifreeze tester with floating balls. They are in expensive.

Most times you need to let the antifreeze run through a little and then add more to make sure

3 thing wrong here, one: you should never change coolant type, every coolant is designed for particular vehicle, compatible with the metal kind, they are not universal, keep the original is the best. Second, never add cold water to hot engine, it will crack your engine block. The last thing, after flush the system you you cannot add 50/50 coolant because it has half capacity water left in it, add 50/50 will make it about 30/70, you risk your engine get frozen in cold winter.

[@raylaux8295]

It's wrong to fill with a mix of 50/50. The radiator only holds 50% of the full capacity. Say 8 to 10 quarts. Draining the radiator after the flush several times (you say 5) leaves about 6 quarts of only water in the block and heater core. Proper method is to add 50% of total capacity15-17 qts concentrated coolant directly to the system then top off with 50/50 mix.

[@ERICSDIYGARAGE]

When you let the car run the thermostat opens and the coolant in the block goes to the radiator repeating the drain and fill of a radiator several times will get most of the coolant in the block out. Also it's not rock science and the mixture does not need to be exactly a 50/50 mixture

[@raylaux8295]

@@ERICSDIYGARAGE Every time you drain and fill with water the anti freeze/ coolant is cut in half . After 4 or 5 times there is less than 1 quart of anti freeze/ coolant in the block. 6 quarts of fluid maybe one quart is coolant a 50/50 mix is not going to get the proper ratio. Radiator will hold 10 quarts 5 quarts is coolant. 16 quart system with 5 quarts of new coolant is not a 50% mix you idiot!

[@johnmills837]

Yep, draining the radiator 4-5 times removes most all coolant suspended in the system. Every time you refill radiator after a drain thins out the amount of antifreeze mixed in the system. It is not correct to use only 50/50 premixed coolant. What remains in the block and heater core is mostly 99% water. At this time to have at least a 50/50 ratio you need to fill with concentrated coolant half the amount of the total system specified in your owners manual. If you manual says 14 qts. then you add half that in concentrate 7 qts minimum then you can ether mix your own 50/50 or use premix to top off to get the recommended protection. This guy is lost

dex cool is shit

[@Lazylynnfeeders]

Well your temp was ok but that was your oil pressure that you pointed to. And why would go from Dexcool to green ? What's the reason I'm wondering?

[@ERICSDIYGARAGE]

Tens years after General Motors began using Dex-Coolas an antifreeze in most of its cars and light trucks, GM car and truck owners continue to complain that the coolant corrodes and clogs radiators and radiator caps, erodes water pumps, rots radiator hoses, causes chronic overheating and engine damage.

[@joseesguapo]

Is there another way to fill the radiator? I put new coolant in my resivor but it looks like the coolant level won't go down and into the radiator causing my truck to over heat (05 Silverado 1500)

[@ERICSDIYGARAGE]

you might have air in your system squeez the Hoses and turn the truck on and keep squeezing the hoses to see if the level goes down and into the radiator

[@livingfastdyingfun]

I've been running yellow coolant in my truck for the last 2 years without any problems. Dex Cool is cancer in an LS, it gels up and clogs everything after 20k miles, the best thing to do with it is get it out of your engine and swap it for a different color, you can use any color as long as you flush it all like he said. Recommended for any Chevy engine other than an LS

[@mike.3727]

Can i do this to my 2008 Chevy Silverado?

[@ERICSDIYGARAGE]

This process applies to 2000-2006 it might be very similar though.

[@mike.3727]

Thanks man. My owners manual says to use Dex Cool, do you think converting it to the Peak Green Antifreeze is better than Dexcool or do you recommend just going by what the owners manual says? Bought my truck used and don’t know what to put in it. Thanks again.

[@ERICSDIYGARAGE]

You can use both as long as you do a Coolant flush as show in the video. Do not mix avoid issues

[@dwjw1]

You guys can do what you like, but this is way overkill. These red/green mixtures work perfectly well together in any combination. I would think that you would be more worried about adding the tap water than the complications that might happen from mixing. All of that adding and removing gives more chance for really bad stuff to get in there from the tap water LOL - like organic matter that ends up growing. I have a 2007 Suburban with 309,000 on it - the last 100,000 were with a mixture of red and green ( I did not flush it when I changed from one to the other) as O'Reilly's claims that they are compatible and I believe they are from my own experience. I find it almost unbelievable that there is no way short of opening the frost plugs to drain the vortec engines. They sure do not drain well from any of the openings in the cooling system. I usually dispense with the little drains and drain about 13 quarts out of the lower radiator hose after pumping out the overflow. The remaining 10 quarts must be in the engine, the heater and on the ground. I sure as the world am not going to put tap water into it to replace any 'red' that still is in there - but that is just me. I have been doing this for about 50 years. The last 25 of those years I have switched from red to green many times with no ill effects on many vehicles.

[@tsuyoxeno9566]

If I’m low on fluids, is it alright if I just add some more and call it a day, I don’t want to go through the trouble of draining everything and all that mess because my coolant isn’t old enough to do that.

[@dwjw1]

@@tsuyoxeno9566 I keep 50-50 on hand so that I can top-off the vehicles without messing around. I have never felt the need to attempt a full flush of any of my vehicles because there is so much residual fluid left in there when you drain it. And when you flush it, the bad stuff gets mixes in with the good and makes it questionable at best. However, the use of household water (tap water) is not ideal - it MIGHT have minerals in it. If you talk to your water supplier, you might be able to find out. Anyway, the point is that trying to get the old stuff out is a futile effort. How much bad stuff can your vehicle stand to have - you will have more than that when you are done. The only reason to flush is when there is some form of precipitate clearly clogging up your heater or radiator. And that virtually never happens. I live in Texas and I would not hesitate to use the tap water for my vehicle water replacement, but 50-50 avoids all of that. In fact the tap water in most of my recent locations around Texas is so good that I would even use it in a battery - I will probably get blowback for that statement, but since I have been out of Minnesota I have not had concerns about the drinking water having minerals in it - just not enough to bother anything. And of course in a battery, when it gets to that point where you need to add water, your battery is not going to survive much longer anyway.

[@jc13781]

flushing with tap water isn't gonna do anything bad as long as you fill with distilled water in the end... a liter or two of tap water, when diluted down with gallons of coolant and distilled water is not going to introduce nearly enough minerals into the system to cause an issue. Not to mention all modern coolants have chemicals to prevent minerals from damaging your cooling system, since a lot of people with leaky radiators will add tap water to the system anyway.

[@unabonger777]

@@jc13781 OR don't put any tap water in

[@jeffro221]

Mixing Dexcool with standard old green anti-freeze causes huge sludging and blocking little coolant passages. Don't believe it? You can see photos of it all over the web. Doing something for 50 yrs doesn't mean you've been doing it right.

[@lgtab1553]

A easier and faster way is to pull the thermostat out while leaving the top hose of the thermostat housing..take a garden hose and place in the upper radiator hose and run the engine and it will flush everything out faster. Then run the car until all water is out

[@ERICSDIYGARAGE]

You will need a new gasket if you do it this way. But yes, I agree it's faster

Calcium build up,. That stuff can look super nasty. So some hoses have metal coiled inside to kinda let the hose stay a certain shape. So it doesn't bend and kink.

[@azeissler1987]

Some years for Chevy hoses have a spring built in to stop the hose from collapsing under pressure from the water pump. Especially the bottom hose.

[@tomkennedy983]

No sure changing the coolant chemistry is a good idea. The manufacture recommends a type coolant for a reason. If you coolant was originally orange then you likely have a aluminum block which typically calls for a specific coolant.
