I was beginning to doubt myself, so dug out a few bolts just to check. Here's an assortment of bolts, each with where they came from. The two on the right are from the thermostat housing and crankshaft pulley. The photo doesn't do them justice, but there is a distinctive green line running along the bolt(s).

Thought this photo would be interesting as it's the bolts from the water pump and thermostat housing. Look at the state of the bolts (+ bolt head) from around the water pump. I had already decided to replace them once I removed them, so obviously a good decision.
