I have a 2017 F150 5.0 Lariat and I noticed the coolant leaking out of the passenger side of the radiator. Is this a common problem? I will be replacing the radiator, upper and lower coolant hoses, that t-fitting (whatever it’s called) and the heater hoses. Is there anything else I should change while I’m in there? Also, should I go OEM or after market for radiator? Thanks

 

You dont say how many miles but I would also do a thermostat and I would use only Ford parts, especially the T stat.

 

Is your transmission cooler separate, likely yes. If it is part of radiator beware of transmission lines as they are often difficult to remove.

 

it has 174k miles
