I'm at 34K. I've had it since 26 or 27?? I can't remember. I'm thinking it would be a good idea, preventitive maitnence kinda deal but i wanted to check and make sure its safe. I know you aren't supposed to change the transmission fluid, just add to it or it could ruin your transmission.
I also bought orange coolant because thats whats in it and it was the most expensive, therefore I feel like its the best! Plus I got some water wetter.
"I know you aren't supposed to change the transmission fluid, just add to it or it could ruin your transmission."
Untrue. In fact, if you do not have the 30,000 mile transmission service done, it will void your transmission warranty. Most of the shops now use machines that do a 100% fluid replacement on auto transmissions, and even if yu use the old "drop the pan" method, you put about 40% new fluid into the transmission.
The orange coolant is supposed to be good for 5 years, so it should still be good (plus I like the clean citrus taste). So if the stuff looks clean and you want to change it "just because", I'd just zoom it out with plain water. I wouldn't bother with cooling system cleaners unless it's really necessary.
Since it looks like you have an 03 spi focus, you should have gold coolant in it.
Gold coolant has a life of 100000 miles. As long as it has good color and has
a freeze point of at least 25 below I wouldn't worry about it. But if you want to
change it, you could just drain and refill.
