Replaced radiator 87 300D... right and wrong way to refill fluid?????

[davidlee]

I was in a small collision that ended up puncturing my radiator. radiator has now been replaced, I introduced new fluids into the system via the plastic overflow bottle on the passenger fender well, It took about 1 &1/2 gal.
I started the car and waited for the thermostat to open so I could finish filling the system, the temp started rising after a couple minutes and kept rising until the car was running much hotter than normal operations. perplexed I got out of the car and looked at the overflow tank and it was still full, I felt the top and bottom radiator hoses and they are cold, the hoses dont feel like they are holding any fluids, though Im not positive on the bottom one since it is a challenge to reach up to, but both are for sure cold, yet the engine is hot? Thats why I am wondering if there is a certain way to fill it up other than the way I did it.. Any advise would greatly appreciated.
