I guess if it wasn't such a hard thing to replace, I guess it would be such a hot topic.

I would suggest that you also replace the level sensor as that is likely to get broken in the process.

i took the time to replace the spark plugs & tubes which had no oil in there and looked fine anyway and upgraded to the newer ignition coils also since i had planned to do all of that anyway and had the parts

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

i just put the interior all back in my car and had an awesome drive today and then come outside a few hours to see this.... ughhhh crap
i think its the darn coolant tank and i already have a new one + the updated cap sitting in a box, it had already stopped leaking by the time i saw it. I am going to pressurize the tank tomorrow and see if its really that. No overheating, no white smoke etc so I am pretty sure its not something serious.
i could see a small amount of coolant on my exhaust tip months ago so thats why i purchased the tank, wasnt expecting to leak that much
wish me luck !
Agreed, and that tank does look to be original. I replaced my coolant tank about a month ago and I can tell you it's not fun. I would suggest that you also replace the level sensor as that is likely to get broken in the process. They're only about $40 from a dealer, probably less online.
I've read many many thread on this subject and how these tanks are known to crack over time. Which surprises me because I have owned cars that are over 30-40 years old and the coolant expansion tanks are one of the few things that still hold up. But not on these cars? Make me wonder why... Is it the combination of the heat and high pressure of the cooling system? Or, just sorry plastic composite? I guess if it wasn't such a hard thing to replace, I guess it would be such a hot topic.
Do we have an average life expectancy on these? I know the PO of my car had it replaced a few years ago and I wonder if I should do it again before putting my motor back in...
Well, I can tell you mine has lasted for 142K miles and is a little over 20 years old (car manufacture date 7/98). I have flushed and refilled coolant several times in the course of other projects. I always use 50/50 Porsche coolant and distilled water. My tank has not yellowed like some I have seen. Also latest -04 coolant cap. And, it is hot in Florida so it gets a pretty good workout most days. I would say if it ain't broke, don't fix it.
Everything is engineered to give out after a certain amount of miles/time
I replaced mine a few weeks ago because the same thing happened to me. It is really hard to tell where the leak is coming from as there could be hairline cracks hidden in the seams or on the side facing the inside of the rear quarter. I paid about $600 to have mine replaced (which I think is worth it unless you have the time, tools, and energy to do it yourself). Part is about ~$250 if I remember correctly.
It is interesting that they seem to age differently. I replaced mine at just under 70k miles and about 18 years. It wasn't leaking but was very yellow and opaque and I didn't want it to give way when I was on the road.
Just replaced my coolant tank a few months ago, 2004 C2 Cab @ 52,000 mi. Same symptom as in your photo, and good advice from previous posts. You'll be fine! /X3
as everyone says its a royal pain to do this
i took the time to replace the spark plugs & tubes which had no oil in there and looked fine anyway and upgraded to the newer ignition coils also since i had planned to do all of that anyway and had the parts
also removed the pse exhaust and going to try the muffler bypass for a while
now i have to do the pass side... but its to darn hot so i am waiting a few days until it cools down
finished and fixed
holy crap aftermarket headers + catless + muffler bypass = insanely loud, to loud for me and i like it loud. so i will be trying to add cats to see if that helps
