What is e7te-ca 5 ford motor?

That's not a standard Ford Motor Company part number or code. It looks like a misspelling or a code specific to a particular repair shop or internal Ford document. To find out what it means, you'd need to provide more context:

* Where did you find this code? (e.g., a repair order, a parts list, online forum)

* What is the vehicle's year, make, and model?

* What is the context in which this code appeared? (e.g., was it related to a specific repair, diagnostic trouble code, etc.)

Without more information, it's impossible to determine what "e7te-ca 5 ford motor" refers to.
