I posted a link to photobucket pictures.

Ok, so I removed the entire seat & assembly for pretty easy access to the front of the engine / rear of the lift.

I removed the aluminum cast hose inlet. I was assuming this is the thermostat housing but there was no thermostat? Is this correct?

Not sure who worked on my lift prior but I'm getting the feeling he/she was a seriously shady "mechanic".

It is hard to see for sure due to all the engine grease build-up but the aluminum hose "inlet" for the upper radiator hose appears to be a part of the cast exhaust manifold?

The smaller diameter (maybe 1" OD) lower hose which is plumbed to the water pump has a kink in it which may be preventing water flow. I don't think this is a OEM hose with the proper radius or bent.

The other hose which is plumbed under the length of the exhaust manifold and connects to the LPG regulator is very difficult to access. I want to remove this hose to look inside. Does anyone know if I need to remove the entire manifold to dig one layer deeper?
