I don't know if I'm in the correct place to ask this question my apologies if I'm not and if someone can lead me to the correct place please let me know I'm trying to find to find a low pressure cap in my 2008 Dodge Caliber SE 1.8l manual. The original pictures are saying its next to the strut tower and coolant fluid but it's not there and I got people telling me it's under the water fluid and coolant fluid containers I'd really just want to find where this is so the rest of my summer doesnt suck since apparently PA just likes being hot I will try to upload a picture when I can of what i am dealing with

 

Find the receiver dryer and start tracing lines. It's easy to spot. The won't hide them.

 

Did you ever find it?
