HOW TO: Install 170° Thermostat
Finally had time to install my 170 degree thermostat in my 13' Ecoboost (This should work on 2011-2014 Ecoboosts). Here's a little write up that might help some:
Parts needed.
1 - Gallon of Motorcraft ORANGE coolant concentrate
1 - Gallon of distilled water
1 - Reische Performance 170° Performance Thermostat
Tools needed.
8mm socket with ratchet and 6" or 9" extention
Flat head screw driver for air intake clamps
Drain pan
Large Taco Bell cup
With an extra clean empty gallon contanier, combine 1/2 the water and 1/2 the coolant. Mix the other half and you'll have 2 gallons of 50/50 coolant
Remove coolant bottle cap
Remove the air intake y pipe in the middle(3 hose clamps)
Place large drain pan directly under the truck below the front of the engine
Using the 8mm socket with extenion and ratchet loosen the 2 bolts on thermostat housing
As it starts to leak coolant out hold Taco Bell cup under to catch most of the mess(your're going to make some mess regardless)
Remove both bolts and remove old thermostat and the o ring
Install new thermostat same way old one came out
Replace bolts, don't over tighten(I was going to torque to spec but impossible to fit my torque wrench in at that angle)
Pour in 1 gallon of your mixture
Start truck, let idle, turn heat on full blast
Check for leaks
Squeeze both upper and lower radiatior hoses repeatedly to get air out
Replace coolant cap
Drive till full operating temperature
Check for leaks
Top off coolant
I had a hard time getting the air out. I actually called Reische because I thought the thermostat was defective. They we're very helpful and helped me determine it was just air. If you have no heat and your temps are climbing past 210 degrees at idle like mine did you probably have an air pocket. Reving mine up to about 4k RPM and holding it along with squeezing the hoses did the trick. It's 30 degrees outside here. Now my temps are 180 cruising and it's hard to get past 195 beating on it. Before it would get past 200 just at an idle. I read some people only needed 1 gallon of coolant, I needed about 1 1/4 gallons, so don't buy 1 gallon of premix as it might not be enough. Hope this helps anyone that's getting ready to do this. It took me 30-40 minutes start to finish.
