Remote Thermostat

Rain again so I got to spend a little bit of time getting started on my remote thermostat setup. This will be consisting of an F22A PT3 thermostat housing and the F22B P0A thermostat cover. I will be using welded AN fittings on the block, upper rad hose housing, thermostat housing and the radiator.

Doing this will allow me to use the appropriate length of SS braided coolant hoses in place of the steel tube usually used on the back of the block. As well as using it for both the upper and lower rad hoses.

Here are a few pics of the cleanup.

Started off with a dirty rusty A6 housing with all of the coolant hose nipples intact.

Within minutes I was down to threading the old 1/4" nipple outlets for plugs and removing the 3/4" inlet hose fitting to make room for a welded -AN bung.

1/8" NTP 27 threads, both of these ports will have plugs in them. Considering I am not going to be using the IACV or FITV. However I decided to thread them just in case I ever need to run a couple -AN coolant lines in the future.

Here are a few shots of it all cleaned up ready for some bungs and plugs!

Mated with the P0A thermostat cover and fan switch. I will probably be replacing the fan switches with plugs as well. I am going to be using the ECU to control the cooling fan along with the electric water pump.

This isn't the -AN fitting that will be welded on, it is only there for representation. ;) That will be a 12-AN fitting and the inlet and outlets for the block, head, rad and housing will be 20-AN. As you can see I am also a few 1/8" plugs short. I used up the ones that I had on my -AN fuel setup. Updates on that to come soon!
