1993 Damon Intruder/P30 454 Overheating

That's kind of been my thought process, that something else is going wrong and the clutch may just be a symptom, even if it's an incorrect clutch. Reason being that even with a hole in the shroud and down a blade (presumably from the blade exiting it there) it got us home fine without any temperature issues. They did replace the water pump, I think I'll ask them for a part number tomorrow to make sure it's the right pump. Based on what I've read in other forum posts and such, the clutch should engage somewhere in the 150-170° range? Roughly equates to 210° on the dash, ideally. Is it possible there's a blockage inside the block from where sediment and other stuff may have settled when they drained the system? Or possibly just a narrow restriction and not a total blockage. I'm also going to verify that the hoses have been replaced, and if they haven't that might be our next step. I've read that old cooling hoses can look fine from the outside, but when put under pressure they collapse internally, cutting off coolant flow

Update: Well, I guess I expected too much that they'd replace the hoses. The top one is super soft, I bet the bottom one is in similar condition
