[QUOTE="SlowSVT, post: 14094156, member: 20202"] I would be a little reluctant making big changes in the cooling system for the sake of a cleaner looking engine compartment. Should something go wrong here (most likely when you need it the most) would be very expensive. The expansion tank needs to be above the highest point of a radiator which will reduce the likelihood of air pockets forming getting trapped in the heads which causes hot spots or worse. That fat factory bypass hose will allow the pump to circulate a large volume of water thru the engine which will maintain a more uniform cooling throughout the engine before the thermostat opens up. I completely redesigned my cooling system but it's not to far off from the factory plumbing. My engine will be the last thing that gets assembled but that is a ways off where I should piece the components on the engine and do a write-up as people are always looking for ways to do things and exchange ideas. if I were in your shoes there is something I would consider which should improve things on several fronts. 1) move your battery to the trunk of you haven't done so already 2) While the factory expansion tank is probably the best set-up as a few of the aftermarket aluminum tanks have been known to burst just after the weld (even a few factory tanks have burst). The main thing I don't like about the factory tank is that it obscures a lot of the airflow out the hood extractors. If your vents are open and there is no tank there you can now see the exhaust side of the rad looking down on the closed hood. What I plan on doing is making a very sturdy aluminum expansion tank and locating it high in the inside fenderwell where the battery use to be. That would do wonders for both the appearance and the functional requirements. I'm not a big fan of the factory system that returns the heater core discharge and returns it right back to the engine which is done to get heat into the cabin quicker. I AN plugged the hole in the cylinder valley in the block so now all the coolant goes thru the rad. If the blower is still on the engine you could cap the metal tube off at the back of the engine. I made my own thermostat housing which really cleaned the system up dramatically. You may have already seen this post but perhaps you may get ideas of your own. This is a bit of work and I don't expect too many people will venture out this far but I'm really happy with the way it turned out.
