Visited the parents this weekend and got overly bored during the day, so i figured i would check off a much needed maintenance job...a full system coolant flush.
Ever since i bought the car, i got it home and did another once over and peeked down in the coolant overflow tank and noticed a nasty brownish green coolant. Its been on the bottom of my to do list, but certainly was needed after you see the pictures.
Started off with 6 gallons of distilled water, which was the perfect amount. And bought 3 bottles of Zerex asian blend coolant. Didnt want to get raped by the dealership for OEM coolant.
Started by lettting the car cool down and opening up the drain plug on the bottom of the radiator. Man was this coolant gross. This was the very first drain.
Then proceeded to remove my overflow tank and give it a thorough cleaning before reinstalling. The pictures were taken after it was cleaned, but it was gross inside and out.
Then put the drain plug back in the rad and poured two gallons of distilled water in the rad and repeated the drain in refill process two more times after that.
This was after my second draining and already looking a lot better.
This was the final old coolant line. Such a massive difference in color and by the end it was 98% clear.
Filled it up with the new zerex asian blend and topped the coolant overflow bottle up and its done! Very very easy process, just time consuming with downtime to let car cool down and let each draining process run its course, but overall a very easy task.
Next small task is tackle the front and rear diff fluid.
