hot by feel is probably not hot...a Pontiac engine is hot when running over 220F... you can buy a cheap temperature gun...I bought one online for $20...then you can see temps all over your engine , and locate hot spots if you have any...my temp gun is small about 2.5" long 1" wide and fits in you pocket...you can also check your own forehead temp, or chilled wines etc w it! lol
