Question about 1997 Lexus LS 400
Drivers side firewall, right beside the head. Its best to be able to see high side pressure as well, using a set of 134a manifold gauges. Do not overfill....Tip....When you remove cap(s) listen carefully for hiss. This indicates leak past schrader valve of service port. To tighten, keep in mind, one has to press down and to the right at the same time, as one wants to avoid loosing freon unnecessarily.Just a quick, light..but fairly firm twist to right, then get off it. You'll probably get a short little shot of freon and oil so protect your eye's and face (this is not an option)The tightening procedure detailed here helps prevent further leaking and cooler car+people! Caution: If you have any doubts about your ability to service any high pressure connection, Let a mechanic do it. This is a small price to pay to keep everyone safe. theroad
