Those can be fun.
Hex head 6mm holding it to the block. They can be crusty and tough to remove, swap 'em with 13mm head bolts in install.
Gotta pull the belt, shock, tensioner and support bracket which involves removing the waterpump and p/s pulleys.
easiest way to get the pump out of the hole is tweak the tensioner adjuster bracket rearward and snake the pump out the front.
Whats scary is how easy they are with the heads off and how tough the 201 with a 103 can be.
