2017 Model Year Product Changes

9/28/2016

1 Comment

 
The 2017 Model Ford Based engines will benefit from a few changes designed to make the product more robust and to make some maintenance procedures more convenient.
 
For the 2017 model year, a change was made in how we monitor the engine to make sure there is adequate water flow. The paddlewheel style water flow sensor that was used during the 2015 and 2016 model years has been eliminated. In the place of the water flow sender, we are using a pair of components called skin temperature sensors. These sensors are installed on each of the stainless steel exhaust elbows just after the exhaust manifolds and before the catalytic converters. If there is a lack of raw water flow in the system, the increased temperature of the exhaust elbow will cause a trouble code to be set.

The codes and the criteria for setting the codes are as follows:
 
SPN 441 FMI 3 Bank 1 High Voltage (Greater than 4.9V for 1.0 second)
SPN 442 FMI 3 Bank 2 High Voltage (Greater than 4.9V for 1.0 second)
SPN 441 FMI 4 Bank 1 Low Voltage (Less than .1V for 1.0 second)
SPN 442 FMI 4 Bank 2 Low Voltage (Less than .1V for 1.0 second)
SPN 441 FMI 15 Bank 1Temp Higher than Expected - Level 1 (Greater than 190F for 8 seconds)
SPN 441 FMI 15 Bank 1Temp Higher than Expected - Level 1 (Greater than 190F for 8 seconds)
SPN 441 FMI 0 Bank 1Temp Higher than Expected - Level 2 (Greater than 210F for 6 seconds)
SPN 442 FMI 0 Bank 2Temp Higher than Expected - Level 2 (Greater than 210F for 6 seconds)
 
Note: Level 1 and Level 2 pertains to derate (power reduction) values. Level 1 power reduction is set at 35% of TPS authority. 35% TPS will leave the engine RPM variable upon load. Level 2 power reduction is set at 12% TPS authority and leave the engine rpm variable upon load.

The other changes for 2017 are primarily for greater convenience during the winterization process.  First, we have added some brackets that give you a place to store the drain plugs as they are removed from the various components. The brackets are labeled specific to the engine so when all of the drain plugs are placed in their labeled storage positions, you are done draining the water from the cooling system.

Square Style Heat Exchanger

​Note: The round style heat exchanger has an anode (P/N 865055) that needs to be inspected and replaced as necessary. The square style heat exchangers do not have anodes.

Note: The transmission cooler on engines with the round style heat exchanger is self-draining.

​Crossover Hose

​The crossover drain hose must be separated to drain the water from the exhaust manifolds. Some models use a connecting block and blue drain plug like in the photo on the right.
