I've recently changed the radiator in my Fortrak, ever since the temperature gauge sits pretty much on cold and the heater runs cold, I'm assuming this is an air lock, any tips on how to bleed it, or other ideas which could be causing this?

This is an important matter,
This is an important matter, your radiator is one of the most important operating components of your automobile. Responsible for keeping your automobile's engine at a safe operating temperature, a malfunctioning automotive radiator could mean big trouble for you if you do not seek professional mechanical attention immediately. This can be due to can be frozen radiator. This happen in cold weather if there is not enough anti-freeze in your radiator. Always check the anti freeze levels before the cold weather sets in, especially if you live in an area that dips into arctic cold temperatures.
you might need too
sometimes when changing a rad u get an air lock when refilling with fluid, what helps is to massage and squeeze the pipes to get it out ( undo rad cap ) after a good run feel the pipes leading to the bulkhead from the engine/water pump if these are cold you have a pump problem, if there hot your lever cable in the dash is broke, something along these lines anyway.
Full of ideas but no time to do them!!

Ideas for you ..........
There is always the possibility that the new radiator is more efficient than the older. The old radiator could have been clogged with rust etc.
I would run the engine and then have a feel around the hoses. Especially touch and judge the temperature difference between the bottom and top of the radiator. If there is a significant difference then there is a coolant flow problem.
Also remove the coolant reservoir cap. When the engine is 'warmed up', rev the engine and look down onto the coolant reservoir liquid. The coolant should 'rise' as the water pump pressurises the coolant within the system. If there is no visible 'rise' and there is a significant temperate difference between the top/bottom of the radiator, then suspect the water pump has failed.
Assuming the coolant pump is working I would next remove and investigate the thermostat. It could be wedged in an 'open' position and the coolant will not reach operating temperature. If you do not know the history of the car, it is possible the previous owner removed the thermostat to 'hide' the overheating caused by a blocked radiator. The most likely cause is a thermostat which is 'stuck open' so coolant never fully heats. If you have already changed the thermostat did you replace it with the jiggle uppermost [the little hole in the top plate of the thermostat]?
