Well my daughter had a crash in our our father daughter s-10 project. We bought a donee car for a $200 and got to work. Damage all seemed pretty superficial and fixable until I removed the water pump. The fan too a hit and it looks like the fan shaft got pushed into the housing behind the water pump and cracked it. See the last 2 pictures. It looks like this housing is removable. Is is removable? What's this part called? Where can I get one? Is it hard to replace? Kind of worried now that we wasted a bunch of time and money trying to fix it. I wasn't expecting this cracked housing.
