Air suspension hummer h2

Your vehicle is equip with air bag system. You probably experiencing an air lost due to air bags leaks or your leveling valve is exhausting air at the exhaust port. Here is what you do. Spray soap with water on spray bottle and spray around the air suspension area. when you see bubbles coming out that's the leaks. fix it. Good luck.

My 1992 tornado trofeo back is lower then the front

Check your rear suspension. Load-leveling air suspension struts could be bad or leaking. Air suspension compressor could be inoperative. Air suspension compressor relay could be bad. Air lines from compressor to struts could be leaking, from cuts, cracks, or having rubbed through against the frame. Transverse leaf spring could be sagging.
And it's Toronado, not Tornado. Sacrilege!

2004 H2 sometimes when I go to my hummer the back end has sunk down. it pumps up as soon as I stat it

Either you have an air line leak or one of your shocks are leaking air. Soapy water can be used to check both problems. Put soapy water on the air line connections and if there are bubbles then that connection is leaking. If you don't find any air line leaks then put soapy water around the shaft goes into the body of the shock and again if you have air bubbles that shock is leaking. It is always best to replace shocks in pairs. In other word replace all of the shocks on an axel even if you just have to replace one. Please rate my answer for helpfulness.

My Hummer H2 is leaking air from both the left

It's not likely that the bags are leaking unless you see physical damage, it's more likely that the compressor exhaust solenoid is bad. There's an updated compressor kit available from GM that requires calibration after assembly. Not cheap.

2003 lancer strut

Yeh.. easy... usually a bad strut will make noise when going over bumps such as clunking, squeaking, knocking. also, pushing down on the corner of the car with the suspected bad strut should make the car feel 'soft'.
Also, a bad strut usually is leaking hydraulic oil. If a faulty strut is suspected, have the dealership or mechanic diagnose and repair the problem.

1995 H1 Problem

hi raymond,

it could just be the overflow of the air conditioning. it could just be plain water which is the water condensate from the air conditioner.

look at the engine compartment firewall, find that hose and insert a long stick that can be inserted and you might un clogged the drain line.

if you are loosing coolant from the thing you are saying and you are definite that it is coolant water and not just plain water, then the heater core could have gone bad and leaking and you need to bring it down for repair or replacement.

have you been adding water to your radiator every time you use the car? if not, then im 90 percent it could just be a clogged air conditioning drain.

tnx 4 using fixya,
