My car is Midnight Blue, paint code 904. It's non-metallic paint.

Side note about the cooling system... the electric fan does not do much while the car is moving at freeway speeds. It's designed to help at idle and/or low speeds. If the car is getting too hot at 70mph climbing a grade, turning the electric fan on earlier won't help much. Definitely check to make sure the fins are clean and airflow is not obstructed...

Don't worry, it no longer looks that clean.

Bio300TDT is correct, that photo was taken shortly after the new head was installed back in 2002. While everything was apart, I did scrub the engine compartment. But unfortunately it doesn't stay looking like that if you actually drive the car. I do try to rinse it off about once per year, mostly to remove dust & dirt... I've managed to eliminate 95% of the fluid leaks. Here's another photo from 2002...

So that's what color the expansion tank starts life as.

LOL... Yup. Less than $50 wholesale, if you have the original tank, I'd replace it at the next coolant change. The new tank will have a silica pack inside that's designed to help control corrosion. The original tanks didn't have that, AFAIK.

I'll put it on my list. I'm on my way to get a rebuilt tranny tonight. I just love spending money on the wagon.
