Hi guys, I have been smelling coolant for a couple days now. No spots underneath the truck. I bought a Stant adapter (part#12026) for my pressure tester. Tried threading on the catch can and it doesn't even come close the the rubber seal. Does anyone know if Fomoco used different catch cans, or reservoirs on my truck
2012 screw FX4 5.0...TIA for all replies

Look under or around the antifreeze overflow tank, look around the "Y" adapter with the hoses coming out and finally, water pump weep hole. If you smell it, you have a leak and a small one that could be dissipating buy the heat of the vehicle.

When I had my first o ring leak, I smelled it and did not see anything on the ground but a small amount on hoses.

Be careful pumping too much pressure.
