The truck is losing coolant, and I can't see where it is leaking

I am getting oil in my coolant bottle but no coolant in my engine oil. I replaced the oil cooler and flush everything but it still happens. When flushing the engine nothing but coolant comes out, no oil. Truck runs great, not overheating, no codes. Has new radiator, water pump, thermostat and some hoses. Noticed some hoses getting swollen I guess from the oil. It is a 2017 F150 3.5l ego boost with 132,000 miles on it. Did a head gasket test and the blue changed to a light yellow. Any ideas?

Temperature sensor where is located
At

P2601, where is the fuse for the cab comfort auxiliary coolant pump?

I don’t know what kind to use

"Where is the coolant temperature sensor located?Here is my problem. I start my truck with the AC on and as soon as the oil and temperature light comes on my AC shuts off. I changed the oil and replaced the oil sensor. No change. So my next step was to change the Coolant temperature Sensor but i can't find it and nobody else can. Can you advise my as to where i can find it or send me a picture or diagram.

When driving the temp gauge will run inthe normal..., range for about20 minutes then it will spike into the red. Check gauge shows up on the dash. Stop and cycle the key and every thing is good. Used o. B. D. Reader. P1299 is the code that comes up. I changed the temp sensor no change. The engine is not hot I can remove the cap on the coolant jug

Large amount of coolant leaking underneath the front of the truck. What can it be? Water pump, Rad or something else.

Yellowish froth on my oil cap. And my radiator was always low. I was told I have a blown head gasket so I put in a bottle of Barrs into the radiator.ir seed to help with the coolant levels but froth is still there.

Why is my truck over heating every 5 minutes I keep losing coolant

Truck is running in the normal heat range. After about 20 min. The temp gauge will spike into the red. I can open the cap on the coolant jug and. It is not hot. I cycle the key and it runs and the gauge is in the normal range and runs there for twenty min. Ichecked with an o. B. D. Reader the code is p1299. Says temp sensor. Ichanged the sensor which is located in the intake behind the alternator no change. Any idea where to check next.
