Title: 2007 Marquis Dash A/C Refrigerant Capacity
Post by: Anand Shah on May 24, 2022, 12:24:12 AM

Hi All,

Does anyone know how much 134A a 2007 Marquis / Patriot Thunder would take?  Assuming the oil is PAG?   Need to replace a line with leaking fittings and the shop was asking.

Thanks in advance.

Anand

David - thanks.  Did not find this in my attempts to search.  But good enough to figure this out!

Just posting final # here -

The sticker on the firewall said 52 oz.   Removed 4 lbs 1 oz = 65 oz

I after replacing the leaking line did a full 30 min vacuum and it took 4 lbs 8 oz - which at 72 oz is way more than 52.  Used PAG 100.  A/C now ice cold for the first time since I've owned this coach, hopefully stays that way.  Lines seem to leak at fittings where there are bends....
