1. Don't forget to instal all the O-rings and be sure to lube them before installation. Double check the O-ring is installed before tightening the fittings......theirs nothing worse then trying to track down a leak in the system.
2. When you mock up the hoses on the fitting take a marker and scribe the fitting and hose so when you take the hoses to the shop to be crimped, the hose maintains the same orientation "if it has a bend or twist".
3. It's a good idea to have the shop that is installing the 134A to add a can of leak detector....just in case!!!
4. keep an eye on the temperature gauge when the a/c is on and it's a hot day. You might need to upgrade the cooling system "radiator, added electric fan" etc.,
Joe
