Hey everyone. I recently purchased a 2019 raptor screw that has been done with Cobb stage 2 and ECU / TCM tuning from goose tuned. Truck is fantastic and is a great upgrade from my first gen. I am happy to be back in a raptor and have a few questions below:
Thermostat: I am looking to lower my cylinder head temp a bit. I spoke with Wilfred and noted the highest temp I had seen on my 8 hour ride home from West Virginia’s massive mountain grades was ~240°. This was at 75mph in 80° humid weather. He suggested the 170° thermostat from SPD and a retune to kick the fans on at 190°. This combo should lower my cylinder head temp to around 220° max. Is my current state a concerning temperature? I will more than likely upgrade my thermostat but wanted to check before I do.
Coolant: In the event I do the above work, is it against the book to put Amsoil HD coolant in the truck or should I stick with ford OEM?
Transmission: I come from the diesel world and checked and changed my transmission fluid regularly. I see there is no ability to check on these trucks and the fluid isn’t really noted from my searches. Should there be a change interval on this truck? It current has 37k on it and I doubt it has been done. No issues at all with hard shifts or bangs ETC but I certainly don’t want to introduce any if I change the fluid and it’s not meant to be changed. Assume it has to be done through a cooler line in an extract and I’d likely have the stealership do this.
Any insights on the above or general maintenance items to take care of at this mileage is much appreciated. Interested to also know if I should do my diff fluid, transfer case, or any grease points that need attention. Thank you!
