On a 1992 244 B230F, how you tell if the radiator is full of fluid and has no air pockets, as the fill line from the reserve tank goes into the middle (side) of the radiator and not the top.

Because it is a total sealed system when the tank reads full believe me it is full.
You have to lines to the tank. One from the top of the radiator and one from the middle of the Rad.
The one from the top is what supplys the coolant to the tank. It returns to the Rad. from the one that goes to the middle of the Rad.

 

I guess I should have phased my question better. I changed the plastic fill tank and in doing so unhooked the hose coming from the bottom of the fill tank then runs to the middle of the radiator and also from the radiator itself.

While doing so some fluid came out of the middle hole in the radiator before I could get it put back on. I installed the new fill tank and connected everything back up and filled the fill tank with fluid. Since the system is sealed and I broke the seal I am concerned.

I am worried about the fluid which was lost during the process of changing the fill tank and mistakenly removing that hose from the middle of the radiator. That is why I was asking how can I tell if the radiator/engine is full of fluids.

Once the thermostat opens the system will bleed out all the air that was in the system.
The air will go into the tank and the coolant will replace where the air was.

It will all take care of itself.

Just watch the level of the bottle.

 

Thanks for your assistance in this and I will keep an eye on the bottle.
