Coolant overflow tank cap removal.

**ZMagnum** · 03-15-2006, 01:10 AM

For some strange reason I can't seem to open my coolant overflow tank. The cap twists and releases some pressure but it won't come off. I don't want to force it off and break something.

Does anyone know how to take it off? I want to have a look inside. My engine is cold.

After the first 1/4 turn press down and turn. You have to press down hard enough to compress the spring while turning.

Ah ha. Thanks. I'll give it a shot.

Though admittedly I've yet to attempt this, I've always assumed it to operate like a standard radiator cap - press then 1/4 turn CCW to release pressure, then another 1/4 turn CCW to remove. No..?

Hmm the childproof police have gone overboard haha

OK, got it off. It is like a childproof cap.

Also, it looks nasty in there. I see some residue that looks like crystals or something growing. I'm gonna mention that at this Saturday's oil change.
