Sir GH, radiator internals are clean (no rust). as per the external, i can say that it's clean. about 5 months ago that i removed the radiator to clean its fins as well as the condenser. from the front, a 1x1 ft oil cooler then the A/C condenser(equipped with an aux fan) then the radiator.

Sir jvnj, items 1-6 are all good except maybe item 2. yes the fan should suck air from the front towards the engine but the timing cover i think deflects all the air towards the hood. hood is equipped with an insulator. at the back of my mind is a defective fan clutch. i refilled silicone oil last year and iirc i did not make match marks before disassembly.

thanks.
