Using the block heater on my 2.7L it gets the coolant temp up to around 100 degrees F.

My normal operating coolant temp this winter has been around 180-190 F. I don't think the block heater is supposed to get the coolant temp up to normal operating temp, only to keep the coolant warm to assist with easier startup and quicker time to normal temps.

1kW at 120V is between 8A and 9A. So you should be ok with a 10A plug, but there isn't a lot of room there.

That would explain why you are seeing some temp response, but not "block is totally warm". It's only able to warm up that one little spot, and the heater is going to cycle when it gets too hot to keep from burning/boiling out - most heaters I know cycle around 180-200F or so. It probably is hitting 140F+ right at the heater, but especially if it's outside, it's a huge hunk of metal sitting out in the cold, so you aren't going to transfer much heat through the metal - I would think you need a little recirc pump.

Our big industrial engines run between 2k and 5kW of pre-heaters - those are large 50L+ blocks, but they have little recirc pumps that keep the coolant flowing. And it will keep the entire block up around 100F+ so It doesn't take much. So you have enough heater there to do it, just need to get it where it needs to go I think.

That or throw a blanket over it.-+

So, I just realized that the user manual states that it requires 220v and optimal temps are reached after 3 hours.

I guess my search for a different timer is required because the one I got isn’t rated for 220-240v nor is the outlet I’m using. So, I guess I need a dedicated outlet, timer and outdoor extension cord.

I agree that the coolant should be 100°F+ in those ambient temps. Oil + coolant hitting 50-60°F after a few miles has been normal operation without the heater. I’m expecting to be able to turn the heater on and immediately be at near operating temps pulling out of the driveway.

So, The heating element looks to be threaded, Is there treads in the block behind the freeze plug on the 2.7?

Did anyone here actually get around to installing a block heater on their 2.7? I bought the parts, but can't find instructions on how to install it.

Doesn’t look very difficult. It just goes between the a/c compressor and the LH turbocharger. Drain the coolant, remove the left fender liner, then just disconnect the steering shaft and move that aside for access. Remove the plug in the block, install the block heater and then route the cord.

Where did you find instructions? I can't find them anywhere, and really don't want to screw it up.

Removal

NOTE: Removal steps in this procedure may contain installation details.

1. Drain the cooling system.
   Refer to: Engine Cooling System Draining, Vacuum Filling and Bleeding (303-03B Engine Cooling - 2.7L EcoBoost (238kW/324PS), General Procedures).

1. LH side only.
   Remove the fender splash shield.
   Refer to: Fender Splash Shield (501-02 Front End Body Panels, Removal and Installation).

1. NOTE: Do not allow the steering column to rotate while the steering column shaft is disconnected or damage to the steering column internal sensor may result.
   Using a holding device, hold the steering wheel in the straight-ahead position.

1. Remove the engine rear undershield.
   Refer to: Engine Rear Undershield (501-02 Front End Body Panels, Removal and Installation).

1. 
   WARNING: Do not reuse steering column shaft bolts. This may result in fastener failure and steering column shaft detachment or loss of steering control. Failure to follow this instruction may result in serious injury to vehicle occupant(s).
   NOTICE: Do not allow the steering wheel to rotate while the steering column shaft is disconnected or damage to the clockspring may result.
   1. Remove and discard the steering column shaft coupler retainer.
      Torque: 22 lb.ft (30 Nm)
      
2. 1. Separate the lower steering column shaft from the steering gear.

1. NOTE: Access the block heater from the inner fender well.
   NOTE: Make sure the block heater wiring is routed and secured away from rotating or hot components.
   Disconnect the block heater electrical connector.

1. Remove the block heater.
   Torque: 41 lb.ft (55 Nm)
   

Installation

1. To install, reverse the removal procedure.

1. Fill and bleed the cooling system.
   Refer to: Engine Cooling System Draining, Vacuum Filling and Bleeding (303-03B Engine Cooling - 2.7L EcoBoost (238kW/324PS), General Procedures).
