The Cart Before the Horse: Spec 3 Build

[Senor_Taylor]

This job took a little longer that I had hoped, but the process was relatively straight forward. I removed the intake, pulled the fuel rail, and removed the hoses from the back of the head to the heater core. I installed a block off plate on the back of the head and deleted the valves that control flow to the heater core. I then removed the coolant hoses that run from the side of the head into the throttle body, then back into the "spider hose" and installed an adapter for my temp sensor in the now empty hole in the head. This is the adapter I used (https://www.bimmerworld.com/Gauges-Data-...apter.html); unfortunately the sender probe from the kit I bought https://www.amazon.com/gp/product/B00UZ9...UTF8&psc=1 was too wide to slide completely through the adapter so I had to drill it out. Then all I had to do was loop the coolant from from the reservoir to the back of the water pump, which is what the spider hose originally did in addition to routing the throttle body coolant and heater core coolant there. I also took the time to pull the blower motor and then put the motor back together. Topped off the coolant and got her up to temp to test the gauge. The gauge required switched power, of which I had none inside the car after the harness thinning so I tapped it into the relay for my fan switch.

Next up is pulling the dash to finish off the majority of the wire harness thinning and delete the heater core. Then onto sound deadening and my M3 top hats.
