If there is no Karcher agent near you, most hardware shops and bearing outlets keep a range of o rings in stock. Take samples ot the part with you to get the correct size and thickness of o ring for your needs. Remember to put a bit of lubricant on the o ring when installing it.

    The recommended oil for Karcher pumps is a specially prepared SAE 15W-40 oil, but general consensus is that the normal SAE 15W-40 oil can be used without problems

    To be honest, I do not know, but my gut feeling is that it would be better to stay with a normal mineral oil. There are the seals to consider and also the possibility of water contamination and I do not know how synthetic oil reacts with water.

2006 Pacifica 3.5L I have a small coolant leak on the passenger side. The coolant will trickle down and drip from oil pan. The puddle is only 2 inches wide. I did a pressure test at 17PSI and I lost 2PSI...

It is a possibility that the leak may come from bad seals from the water pump or a bad water pump. If you also observe bubble in the coolant inside the radiator when the car is running or water coming out of the exhaust you may have a bad head gasket. The coolant comes out of the bad part of the head gasket near the outside which lets water outside the engine as well.

Comperssor runs and there is pressure from the tank gauges won't put out more than 20-30 lbs.

indicates the pump has lost its capacity, assuming the line from the pump to the tank is not leaking,,, a few things could have happened, most likely a valve in the head plate has broken, or head gasket has blown. Third would be he compression ring on the piston has worn out and needs to be replaced. advise you get a parts breakdown on the pump and have at it ad start looking for something broken in the head first.

Karcher/Winner 11 - motor pulses when hose is not operating

Hi, I had the same problem, Replaced the O rings and the rubber seals and cups inside the pressure washer and eventually the hose itself burst. Turns out the hose was leaking, internally between the inner sheath and the outside plastic cover, for quite some time and this caused the pulse. New hose and pressure cleaner is as good as new.
