Coolant Flush?

I have not done this for 2 years should I do it? What is the best way to flush a system? I have a 3400.

how many miles are on your car?


i had mine flushed at about 52k but only because the car sat for 7 months while i was overseas.

well I have 100,000 KM on it so around 65,000 miles. I have put around 30,000 on my car. Sometimes my temp gauge well get up around 3/4 but most of the time stays just above half.

Oh also my car sat for around 6 months

my car never has never gone up around 3/4. if i let it sit for an extended amount of time it will go a needle width above half but usually it stays either right at half or just below. the main reason i got mine flushed was because i didnt like the color of the coolant. it looked dirty to me.

Performance wise well it affect anything? Cooler is better right?

our cars use dexcool coolant. which is good for 100,000 miles.

ok cool good to know. Something I never thought about.

One thing I have found is sometimes my coolant level well drop right down super fast over a matter of a day. No marks on the driveway so it didn't leave my car. Took a black light under the hood and nothing. Anyone think of why this would happen?

Lower intake manifold leak. <_< Pull the cap off the coolant res. and see if the coolant has a crap-color to it. Is there a sludge substance on the bottom of the cap? Check the oil: does it look foamy @ all? No matter what the outcome: If you're SURE the coolant didn't leave the engine, CHANGE THE OIL. Coolant getting into the motor and mixing with the oil will "spin" bottom-end bearings in no time.

I well take some pics. Sure hope its not that. Was reading on the site here some people spent over 600.00 to fix this problem.

picture I don't see much different then what my other cars look like.

Maybe Im wrong heres a pic.
