what is the tyres pressure for Mazda 626-2.48 1992(low pressure tyres)
Either your handbrake switch is broken and will not turn off or you have low brake fluid.
The 1998 Mazda 626 low pressure port for your air conditioning system will be on the top of the air conditioner compressor. The low pressure port will be on the left-hand side of the compressor.
The 1990 Mazda 626 air conditioning low pressure port can be found on top of the air conditioning compressor. The low pressure port should be labeled.
it should be in front of the radiator like on my 1998

I believe you can but normally when it engages low its a sign that the clutch should be replaced soon.
I have a 99 Mazda 626 and mine is on the passenger side of the car. Look for a black cylinder close to the firewall. You should find a small screwoff cap on the black cylinder. This is where you connect your hose to add freon. The high pressure and low pressure service ports are different sizes, so you can't get them mixed up and connect to the wrong one. Hope this helps!
Its best to use a set of a/c gauges but if you are not then just add the freon to the low side which will be the larger hose (suction side)...
