Hi, all. I'm currently rebuilding my DE engine for a turbo conversion. Plus I'm also modifying the cooling system, including deleting some of the superfluous coolant hoses.
Can someone tell me: is it me, or is hose #1 completely useless?? It goes out of the hard pipe, and back into the same pipe slightly further up. It's called a bypass pipe, but it bypass nothing!
Also, I'd like to delete hose #2 if possible. Will that negatively affect the cooling system or cabin heater system in any way?
