Periodical care? Is that like taking care of magazines? I don't miss the destruction of grammar in that business.

Anyway, I assume you have one of those temperature guns? I bought one on sale for $9.99. The temperature throughout the core should be consistent. You also can remove the sylphon (bellows) and inspect the top of the tubes. I don't know who advised against removing the radiator for service, but if the above diagnostic indicates blockage the tanks need to be removed and the tubes cleared with a rod. A cheaper method is to cut open the lower tank only and proceed thus.

If the radiator checks out, then unfortunately the block probably should come off and be inspected, but before that remove the water jacket at least and examine the condition thereof.

Oh, one other item: The lower radiator hose should warm from the radiator toward the engine. If it is warming from the engine to the radiator that indicates blockage. When the engine is warm there should be a uniform temperature decrease from the top of the radiator to the bottom. As a guide warm up your modern car and observe the difference between the radiator intake and outlet (if they are accessible).
