Hi there. I replaced today my coolant. Is the first time that I did it. I made it as follows:

1.- Open pressure cap.
2.- Remove Radiator Petc0%$
3.- Drain all the coolant.
4.- Re-Install petc0($, added radiator flush liquid and tap water. Let the engine run 10 minutes with the max heat inside.
5.- Remove radiator Pet., drain water, add hose water until clear water runs out the radiator with the petc0/( un-installed.
6.- Drain Coolant reservoir and add new coolant and water mix.
7.- Re-Install Petco=#, add cooland and water 50-50 mix, run engine and burp system.

My main concern, is why I just used about 3.5 quarts to fill the coolant reservoir and the regular coolant inlet....

I just changed 3.5 quarts (radiator and reservoir) of the 8-9 that the whole system uses?

I´m confused...

 

It appears like you only drained the radiator. It takes a gallon of coolant AND a gallon of water to refill. Then add the balance to the recovery take.

When you did the flush, did you notice the color of the liquid......should be almost clear (depending on the brand of flush fluid)?

 

Thanks for your answer Snoopy!

It was clear the flush liquid

The question then is, how I change these two coolant gallons? May I keep it as is?

 

Well you PROBABLY could. You reinforced what was depleted...something like 50%.

But if it were me, I'd do the job complete. You have some pretty hot weather to content with and wouldn't want to have unexpected problems later.

The easiest way to explain this and for you it would be the longest way time wise.....

Drain like before, refill with water, install cap and run engine until HOT. Then start the process over again until you do see clear water at the drain cycle. Then close the petc$ck and refill with the 50/50 mixture. Run the engine and continue to add coolant mixture until filled.

There are other methods, but this might be best....although time consuming.

Oh, and I don't believe you ran the car long enough to open the thermostat and get a good flush.


Sorry, need to leave right now...maybe someone else will jump in.

 

What is the trick to replace all? There is a plug on the block or something?

 

If you only drained the radiator, the rest of the coolant in the engine stayed there. Then when you put the flush liquid in and ran the engine, you diluted the entire coolant mixture to below a 50/50 mix. Then when you redrained the radiator and refilled with 50/50 and ran it again you have resulted in a less than 50/50 mix and you still have flush fluid in the engine passages.

From the 2010 shop manual for LE8 & LE9 motors: remove coolant pressure cap, raise & support vehicle, place drain pan under right side lower radiator mount, open radiator drain ****, drain the cooling system, if a complete block drain is required place a drain pan under the water pump drain, remove the water pump drain plug, drain the cooling system. Then to fill, replace the water pump plug and tighten to 16 INCH-lbs, lower vehicle, slowly add 50/50 mix to the cooling system until level reaches and maintains slightly over the cold fill line on the surge tank, replace the pressure cap on the radiator, start the engine, run at 2000-2500 rpm for 3 minutes, allow to idle for 30 secs, shut engine off. Top off coolant as necessary, fill coolant reservoir to cold fill line, check for leaks.

What I would recommend to you now is to bring the vehicle to the dealer, tell them what you did and then let them correct the cooling system so you don't screw the pooch with your motor. The cooling system is right up there with the oil system for protection of your motor and the damage from improper service for either system is catastrophic. Hope it works out for you.

 

fluid was cool in radiator when you drained it last?
how much of the 100 percent antifreezed did you ad?
what type antifreeze did you add?
did you or can you purchase locally a antifreeze tester to see what percentage anti freeze your system is after it has been run and cooled down a couple times?

 

X 2

I'll agree with Sidecar, the coolant is compromised now Juan, and that isn't good. Overheating could be the least of your concerns, the PH of the coolant is now all screwy so you can have corrosion problems with the head and block, blown water pump seals, and possible damage to the radiator and heater cores.

Get it to your dealer or a trusted and competent radiator shop as soon as possible, it'll cost you now, but the expenses caused by bad coolant will increase your future costs by a significant factor.

 

x3 after re reading it it appears that you only filled ran and drained about 1 or 2 times so you are bound to have a coolant flush and old coolant in the mix

 

That is not good then....

To be honest, I don´t want to deal with dealer or shop. Dealer causes mores problems than solutions, and believe me, I don´t want to have a mix of green stuff with dexcol and tap water. You need to live in México to understand me. I purchased two gallons of DEX-COOL Coolant on my last trip to the US border because is HARD to find this stuff in México (This is another story)

What if drain again the radiator and the Water pump plug (I don´t know where is located, require assistance)?
