It sounds a lot to me like the intro to "Glory Bound" by the Wailin' Jennys.
It goes into the cap on the valve cover.
Red, 5 year, HOAT type.
the spring end goes into the engine
The fluid goes down the dipstick tube.
The engine holds 5.
Normally goes to the starter or starter solenoid.
The 3.6L holds near 6 quarts.
depends on the engine on the 3.3 there is a thick black hose that goes from the radiator to the engine
any brake fluid that has a DOT 3 rating will work
Just replace it, the sensor on the top of it is usually what goes bad.
The drivers manual has all that info in it.
There is no minimum vehicle speed. It goes off of acceleration or deceleration in the crash.
