This hose should be replaced! It can see as over 300psi of pressure. To replace, first pull from a/c compressor(it is the smaller diameter aluminum tube) and remove all supporting bracket and bolts. Next follow this tube to the next connection near the fire wall, use two wrench's to seperate. There you go, hope this helps

2002 xterra a/c freon leaks out but it's not the hoses.

The front seal on the AC compressor is very likely the problem here. It can leak with no apparent signs of leaking like older R12 systems because the oil used in the R134 system is synthetic and it evaporates.

Water leaking under dash on the passengers side of 2000 xterra

Only 2 things this can be. The air conditioner drain is plugged, or the heater core is leaking. If the water smells loke antifreeze then the heater core is leaking and needs replaced, if no smell then the AC drain is plugged. You can acces this from und3er the vehichle, should be a small tube near the firewall to drain outside the cab, just runn a wire up in it and see if something comes out like moldy water!

I have a 2000 Nissan Xterra and I'm having AC problems. We've replaced the evap. core and expansion valve. I've also replaced the AC lines and the thermo control amplifier. The AC is not nearly as...

A Chiltons/Hanes repair manual for this Xterra will have the A/C schematics you need. When you replaced those parts did you re-charge the system? You may have a refrigerant leak.

3.3L Engine


Fig. Thermostat assembly and related components-3.3L engine

NOTE Never remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure engine coolant escaping from the radiator.
  1. Be sure the engine is cold.
  2. Disconnect the negative battery cable.
  3. Drain the coolant. Properly disposed of used coolant.
  4. Remove the upper and lower radiator hoses. Remove the fan shroud.
  5. Remove the drive belts and the pulley bracket.
  6. Remove the water inlet retaining bolts.
  7. Remove the water inlet and the thermostat.

To install:
  1. Installation is the reverse of the removal procedure.
  2. Be sure to apply a continuous bead of the proper grade and type RTV sealant to the housing.
  3. Install the thermostat with the jiggle valve or air bleeder at the upper side.
  4. Be sure to refill the cooling using the proper grade and type engine coolant.
  5. Start the engine and check for leaks.
  6. Start the engine and allow it to reach operation temperature. Recheck the coolant level, fill as required.

Hope helps (remember rated this)

I have a 4x4 4.3 V4 2000 Blazer, I have a problem, on the co-pilot seat floor, it seems to get soaked every now and then, and the engine coolant recipient level starts going down, Are there any hoses...

Yes! There are Heater/AC Hoses on the passenger side. Your hose connections may be leaking, or the hoses themselves may be leaking. The Heater Core itself could be leaking. It is best to remove the Glove Box and Dash components on the passenger side including the lower kick panel and expose the Heater Core to find out where the leak is coming from.
It could be as simple as tightening a hose, or hose replacement, or replacing the Heater Core itself.
Let me know if this helped.

My ac on mt 2000 xterra works when it wants to but

you have a electrical problem either in the control panel or the a/c compressor clutch connector
tray by moving the plug on the side of the compressor clutch. if that engage and disengage the clutch replace the connector "pig trail".
but if that don't change wait on till the a/c is not working unplug the a/c compressor and cornet a test light on the loose cable
if you don't get any power replase your climate control module.
