STICK IT IN YOUR RAD AND TELL FOR SURE IF YOUR ENGINE HAS OPENED TO THE COOLING SYSTEM

WHY ARE YOU YELLING AAAAAAAAAAAAAAAAAAAAAAAAAA

CRUISIN Veeky Forums

There's like at least 5 different Youtube videos where people go through how to diagnose a bad head gasket. That's one of the tools you use to tell. Usually you can tell from the white plume of smoke out the exhaust or the shitty milky residue in your oil. But not always.

If you replaced the radiator - did you burp or bleed the coolant afterwards?

I'm sure this is a troll thread, but...

Fix this immediately and stop driving the car until you do. Overheating an 00/01 is a great way to crack the head.

>400k on the clock
Doubtful given your lack of maintenance, but on the off chance this is real you need to replace your entire cooling system well before this mileage. My waterpump went at 150k.
