spray some PB blast under the cap if possible, let it sit, then use a hair dryer to heat up the cap. Use a large wrench to slowly open it, it should open. Don't jerk it because will probably crack the plastic.

if you are not comfortable doing that, let a mechanic do it so they will assume liability
