Dark Coolant means you have a leak some were right??
If you remember I changed my heater core out before winter, replaced all my hoses and flushed my system out. The coolant stayed perfect until now. I noticed it was dark brown instead of green. Its not oily or milky. I looked at my thermostat housing and noticed the gasket is all messed up an there was coolant dripping off it. So I think I am going to go buy a new one, and re flush my system.
i thought you were supposed to use the ''red'' coolant with newer engines....
but when in doubt, pull it out....
wouldnt hurt to change the gasket and flush it
Mine is a 03, but I hear ya. I guess I should do this before the meet :PQuote:

I would think the only part of his system that isn't stock to the motor & water pump is the radiator. OBS radiator made of something different that would react to the new style coolant?
A 98 shoud have had an al-you-min-eeeum radiator with plastic tanks like a newer whatever his 6.0 came from.
Weird but sometimes grounds can cause stuff like this too.
For over the road trucks with cat engines we replace green at that interval and extended life at 6 years 600,000 miles.Quote:

You've obviously f'd up something big time, but you're sure that you're not looking at your blinker fluid?
Blinker fluid is hot pink and glows in the dark everyone knows that. Except for extended life which has green strips in it.Quote:
