Summary
This article supersedes TSB 20-2150 to update the production fix date, Issue, Action, and Service
Procedure.
Issue: Some 2015-2019 Transit vehicles built on or before 31-Dec-2018 and some 2017-2018 E-Series
vehicles equipped with a 6.8L engine built on or before 16-Jul-2018 using the Motorcraft® Orange coolant
may exhibit an engine or transmission overheat concern. This condition may be due to deposits from the
engine coolant becoming trapped in the radiator preventing coolant flow. To correct the condition, flush
the cooling system, replace the radiator and fill with Motocraft® Yellow coolant.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all the following
criteria:
• One of the following vehicles:
- 2015-2019 Transit vehicles built on or before 31-Dec-2018
- 2017-2018 E-Series vehicles built on or before 16-Jul-2018 equipped with a 6.8L engine
• Originally equipped with Motorcraft® Orange coolant
• Vehicle engine or transmission overheats
NOTE: Part quantity refers to the number of that service part number required, which may be
different than the number of individual pieces. Service part numbers contain 1 piece unless
otherwise stated. "As Needed" indicates the part is required but the number may vary or is not a
whole number; parts can be billed out as non-whole numbers, including less than 1.

Service Procedure
1. Perform the following inspections:
(1). Inspect for signs of engine oil or transmission fluid in the coolant degas bottle.

(4). For transmission overheat concerns, use the symptom chart in Workshop Manual Section (WSM)
307-02, Diagnosis and Testing, Transmission Overheating, to rule out other possible causes.
2. Do all of the inspections in Step 1 pass?
(1). Yes - proceed to Step 3.
(2). No - this article does not apply. Refer to WSM, Section 303-03 or 307-02 for normal diagnostics.
3. If equipped with a mechanical (non-electric) cooling fan, perform a fan clutch test by spinning the fan
blade by hand. A light resistance should be felt for a correctly operating fan. If the vehicle is equipped
with an electric cooling fan, perform a fan test by starting the vehicle and allow it to idle. A correctly
operating cooling fan will turn on as the vehicle reaches operating temperature. Refer to WSM, Section
303-03. Does the fan clutch test pass?
(1). Yes - proceed to Step 4.
(2). No - this article does not apply. Refer to WSM, Section 303-03 or 307-02 for normal diagnostics.
4. Remove and inspect the thermostat. Refer to WSM, Section 303-03. Does the thermostat pass the
WSM visual inspection?
(1). Yes - proceed to Step 5.
(2). No - this article does not apply. Refer to WSM, Section 303-03 for normal diagnostics.
5. Flush the cooling system. Refer to WSM, Section 303-03.
NOTE: Flush the system until the water is clear of any soap bubbles.
6. Replace the radiator. Refer to WSM, Section 303-03.
7. Fill and bleed the cooling system using Motorcraft® Yellow coolant. Refer to WSM, Section 303-03.
