If the thermostat is doing its job of metering flow to the rad to keep the engine temperature constant, it is absolutely normal for the rad to be hot on the driver's side and cool on the passenger side. That is the direction of flow, and that is the function of the radiator. The coolant comes in hot through the hose on the top of the rad on driver's side. Exits cooled at the bottom of the rad on the passenger side. If the engine temperatures are fine, the hot2cold side across the rad is absolutely normal function. The only time the whole rad should get hot is when all temperatures are up and it is a hot day out there, where the cooling system is full out and possibly struggling to keep the engine temperatures down. |

Is this just an observation or is there a problem you are concerned about, or trying to solve. What is the engine temperature on the gauge on the dash? Is it running hot, normal, or cold?

No argument from here. We are saying the same thing.
The OP needs to elaborate more as to the conditions and whether it is just an observation or if there is actually a problem to be solved. |

Has the radiator ever been flushed? it sounds like it may be plugged.

this is a problem im trying to solve.the top radiator hose gets hard as rock,i loose heat when this happens and over heats,i pull the relief button on the radiator cap and and get my heat back and the temp goes to normal
