now it all makes sense. Thanks. I'm going to do this when I get back in town.

 

I routed the coolant return on the passenger side using a long curved radiator hose. I do not know the dayco part number for the hose, but I could probably figure it out. It is a very tight fit though, at least how I routed it. If I had to do it over again i would run it on the drivers side over the turbo manifold using a stainless pipe. I modified the OEM thermostat housing to be used as a remote housing and placed it right by the radiator. I still use the ports in the housing to feed the oil cooler and throttlebody, so the thermostat gets flow while warming up. I made a 1" thick aluminum spacer to house my sensors and the feed to the heater core. This spacer goes on the back of the block between the head and a 1.6 water neck which points the hose towards the passenger side. The boss for the sensor on the 1.6 waterneck had to be sawed off and welded shut to clear the firewall. I believe a 1.8 water neck would point it towards the driver's side and not require any welding. I made a simple aluminum block off plate for the front of the block because I couldn't find the correct size freezeout plug and I think the plate looks better. Here's some pictures:





I used a larger fitting to feed the heater core than what is in that picture. Unfortunately it was too big and I have to run a restrictor (.250" hole) in the heater core return line (going to OEM mixing manifold) or else it'd overheat a little in the summer. Also I have a very difficult time "burping" the system whenever I change the coolant.

 

I found that pulling up on ramps makes the "burping" much easier.

 

I need a mill.

 

Nah. Hole saw, drill press, belt sander would work fine.

This should help a ton, once the pics are released
