Low and High side locations of air conditioning on 1990 Honda Accord EX.
Can someone tell me where is the low side and high side of the air conditioning of a 1990 Honda Accord EX? Is the low in the back and the high up front near the radiator? Also, does the coolant go only in the low side?

RE: Low and High side locations of air conditioning on 1990 Honda Accord EX.
HP connection is on the drivers side near the radiator, and impossible to access w/o a 90 deg adapter. It is a non-standard (won't fit R12 hoses directly). LP connection is on the large LP hose in center of car (this is by memory as I no longer have my (90Ex) and will fit R12 hoses directly.
Coolant for diy should be installed only in low side. If you lost the coolant entirely, a vacuum pump is necessary before charging. It's much easier to get charge correct, by vacuuming to completely empty and charging by weight or cans of refrigerant. Charging should also use a manifold gauge set to know that pressures are reasonable.
W/ correct charge both lines to the evaporator (firewall on pax side) should be very cold.
