The clutch is thermal, it has the spring on front. I pulls hard at startup. Still spins when warm but doesn't seem to have the same energy. I'm judging this by the noise level.
We'll see tomorrow...
On another note. I pulled a few of the plugs & they look as they should..Good!

I drive Land Cruisers, and they are notorious for capturing bubbles in the cooling system. Some things I'd recommend:
Put a filler "T" in the highest hose in the system and fill from that while the engine is running.
Get the front end up so that the rad cap is the highest point in the system, and fill from there, with the engine running.
Get one of these things and use it, following the instructions.
