My Dad invented the filler cap for the coolant reservoir on the Ford Raptor.
Because the Raptor sees off road use Ford was having a problem keeping the coolant from ending up all over the engine bay. They came to Dad and within weeks he had a working prototype. Just today he was awarded the patents for his solution. Because he works for a corporation he gets his name on the actual patents but the company owns the rights. That’s just how it goes.
Below is his description of his solution:
The Raptor had a non pressurized overflow coolant bottle. When the coolant system expanded, the coolant goes thru the radiator cap, thru hose, to storage bottle. When the system cools down, it sucks the overflow coolant back into the system. Non- pressurized system reservoirs need vent holes to let the air out & in during the expansion / contraction process.
Normal street vehicles don’t see the bouncing & violent activities off road sees. During off road activity in the Raptor, the coolant in the overflow bottle sloshing around would squirt out of the vent holes ( 3 vent holes in this cap ).
This cone was inverted to snap into the existing cap. We just had to modify the cap for 2 holes that the cone could snap into. ( The slot was already in the cap )
There you have it. A little peek at part of the automotive industry. I will have more as my Dad also did the coolant bottle for the Wrangler and Dodge Nitro among many other vehicles. He is currently working on windshield washer bottles and has even made combination bottles and semi bottles.
I hope everyone enjoyed my first post. Thank you for reading.
