OEM is the safer alternative. According to Nissan, their coolant does not contain any amines, borates or silicates, making it friendly to aluminum and water pump seals. OEM coolant is really not that much more expensive than other brands. I'd rather be safe than sorry...

The ethylene-glycol in the Toytota/Honda/Nissan brands helps to clean and is easy on the water pump.

I'd just go with one of the foreign brand, you won't have to worry about things being bad for your car. Just completely flushed my fluid and am using the Toyota red coolant. Matches my car too even though you can't see it after putting it in.

Shold I use regular Prestone as antifreeze (like on motorvate), or should I use the OEM type?

I'm also a firm believer in using distilled water with the coolant. Some tap water is loaded with minerals and various chemicals...not sure how these will react with aluminum and other cooling system compontents over time and at high temps. BTW, Honda-branded coolant is very similar to Nissan and toyota in that it's safe for aluminum, water pumps, etc. I bought some to top off our other car, and they got me for ~$14/gal... and it is premixed!

Yup! And the Honda dealer is very proud of their prices! In all fairness the coolant must have a good additive package though, as the Honda factory service manual doesn't call for a coolant change for 10 yrs/120,000 miles, then 5 yrs/60K thereafter. I don't think they even sell the coolant in concentrated form (mix yourself)...at least I didn't see any when I bought mine. They did, however, offer the premix in quarts for some ridiculous price...that's why I opted for the gallon. I can speculate the reasoning for selling the premix in a number of ways...they make more money; they can control the optimum mix using their coolant and distilled water for best performance in Honda vehicles; they think customers are a bunch of dummies and can't mix two liquids 50/50...take your pick

It just says that it contains a special additive package for extended use and compatibility with aluminum. As stated in another post above...use (Prestone) at your own risk...

A little bit may not hurt your system. I tried some Prestone extended life antifreeze a couple of years ago in my truck. I eventually took it out because it would crystalize. It even looked funny when I took the radiator cap off to check the level. If you drive an 03 Max, it should be worth it to get the recommended coolant for it.

Picked up my Toyota coolant yesterday for my flush/refill today.
Question: If you are NOT going to remove the engine coolant plugs, is it necessary to perform the operation on the HVAC controls (Turn key to ON, turn heat to hottest temp for 10 secs, Turn key OFF)?

If you don't drain and flush until the water runs out clear, there will still be antifreeze mixture in the block and heater system. You will probably have a hard time removing the plug on the firewall side of the block if you decide to remove them. The 10 second deal is to make sure the damper for the heater inlet hose fully opens. What color os Toyota's antifreeze?
Yes, I did let it drain thouroughly with the radiator cap removed and the heater open.
After refilling I take it for a short drive (2 miles) with the heat at maximum. I (and Nissan apparently) would not recommend removing the engine block plugs. From Nissan literature, they beleive it will make it much more difficult to bleed. Also, be sure to note that there is not rubber washer for the 2002 - 2003 (maybe others) drain plug. Our drain plug comes with a rubber o-ring.

I finished around 6pm yesterday (starting at 11am). For me, it took 7 gallons of distilled water ($5.75) and 1 gallon of Toyota Antifreeze ($15.95). I bought a second and used about a teaspoon to top off the radiator although I suspect I will need more as the engine burps itself.
Total cost:$37.65

Another option is the Citgo Lube up the street lets me drop off oil and radiator fluid from time to time. Don't know how they would feel about 8 gallons though.

Here is a Material Safety Data Sheet (MSDS) for Prestone green antifreeze. Notice that the main ingredient is etylene glycol anywhere from 80-95%. 1.5 % is water, 0-8% Diethylene glycol and less than ½ of 1 percent Tolytriazole. I don't know what the Toyota and Honda mixes contain. I will keep reserching though.
