Well I checked it again today, and added a bunch more. I have never topped it off since we got the truck in August, and have done some heavy towing with it.KEVSTER wrote:You should be fine, most antifreeze is all the same in retrospect. and only 1 qt added, I wouldnt lose any sleep.
Scratch that, they are not interchangeable so that answers that!disallow wrote:Well I checked it again today, and added a bunch more.

I may start a new thread for this, but I was wondering if the caps on my cooling system are reversed? There is a cap for the rad and a cap for the overflow bottle.
Which cap goes where? 1 cap is just that, a cap. The other is the pressure cap with spring assembly etc in it rated to 15 PSI.
So where does the pressure cap go?
Thanks for the tip. The honda premix I have is silicate and borate free as well, but has a blue colour to it. I did some reading, and in fact alot of nissan tuners use the Honda blue stuff in their nissans, so I think I should be OK.LittleStevie wrote:I actually just changed the coolant in my '05 today, with 50k miles.
The cap with the spring came off the reservoir, the radiator cap is just a cap.
I'd be a little cautious with what coolant you put in though. I was going to use the typical Prestone but the guys convinced me to stick with OEM in another thread, and it's probably a good thing. The Nissan stuff indicates that it doesn't contain silicates or borates, which could damage seals or cause corrosion...not sure if Prestone complies with this. Also, the color is a deep forest green that looks something like NyQuil, rather than the typical neon green that I'm used to seeing.
The Nissan stuff was pricey, at $28 a gallon, but I'm going to stick with it. I was only able to drain about 2 gal from the system, so it's only about a 70% change. I decided against flushing the system because the coolant came out looking great (clear, no flakes or obvious contaminants) and I didn't want to mess around with trying to get a 50/50 ratio with not being able to drain the whole system.
