Reasons to change your coolant

[480sx]

After a few years coolant becomes really corrosive. I bought this car at 126000 miles, and have had it for 3 months. The pics speak for themselves, CHANGE YOUR COOLANT! ^^

No, thats not muddy water, thats the coolant that was in my intake manifold.

yeouch.... I hope you plan on doing a flush!!! That looks like coolant that someone has added a StopLeak additive to it....

looks like its not coolant in there but water. my friends looked the same cuz someone filled the system with all water.

Water doesnt eat through metal heh.

[Cpt_Impossible]

yes it does... ask shops that rebuild engines, water alone can do very bad things.

especially when the rust starts to form and the water/rust goes through your entire system. That does not look that bad. Just flush it out with water and have the right mixture of coolant-water.
