Take the passenger side tire out and a few plastic pop rivets and you will have clear access to the pet****.

That is how I get to it anyhow. I have equal length synic headers + skid plates, I know what you mean by no room.

Awesome, thanks man, that didn't occur to me. Shouldnt be much of a problem as most of the fender liner is held on by zip ties thanks to the FMIC

Is it just me or does this simple process seem to be getting WAY over complicated? As for slowly adding coolant to the small resivore on top..... Why dont we just fill up the radiator, then add coolant to the recivore on top, then to the overflow..... put the cap back on the radiator..... leave the cap off the top resivore, start the car and let the coolant cycles through the block to burp, and add as needed to finish?

I'm not sure if it really makes a massive difference. When I did this I filled the radiator first, put the cap on, then put as much in the upper cap as I could. I started the engine with the upper cap off and just filled it a bit at a time until it stopped taking any more. Instead of burping it, over the next week I paid close attention to the reservoir and I added a small amount of coolant every day until it had taken the full two gallons of coolant.

For me, it took exactly two gallons, I've had to add no more since the two bottles of premix Peak I purchased were emptied and in the reservoir it's at the "full" line. Has been for months since I did this.

It is to some degree. There are other ways to fill the system. The way described is pulled from the Owner's Manual. You can fill the radiator first, and continue to fill at the filler tank since it is the highest point in the system.

You can also do a continous pour as some describe, but you need to pay attention to the temperature of the block. When the coolant is first added, there is a lot of air in the system that causes it to heat up rapidly. You would overheat the car quickly if you're not careful.

The writeup is intended to help someone that is changing their coolant for the first time.

Yeah, but keep in mind that the oil in the engine also provides cooling for the engine. Just as long as you keep adding coolant the second more can be added, I don't think there's anything to worry about. When you're in the process of refilling the coolant air pockets are basically unavoidable.

Hey guys, I'm going to do this today.

I want to try to get rid of as much of the green coolant as possible since I will be using the new blue version.

If I have everything drained, can I just keep pouring in the distilled water to flush it out and this for a little bit, THEN Screw the drain plug and fill it with new coolant?

Has anyone done this?

Just pouring distilled water through will not work very well. It is a little bit of a pain to do this, but I recommend that you refill the system with distilled water and run the system. Then drain it again. Repeat as many times as you want until you feel that enough of the green coolant has drained out with the distilled water. I plan to refill and run my system once or twice with distilled water before pouring the blue in.

Can you fill it back up with water from a garden hose to "flush" our the coolant before you fill with actual radiator fluid?
