Can someone suggest to me what type of coolant should I purchase before I change my radiator/intercooler fluid? Is regular Prestone ok? If so how many gallons would I need? Also what kind of Transmission oil should I buy to change the transmission fluid? I've heard of Mobil 1 making a good tranny oil..

Last question is whats the part number for a 170 degree thermostat and Should I go with a Stant brand? I know when I go to autozone or pep boys it always confuses them when I tell them what kind of truck I'm putting it on so should I just tell them a 5.4 F150?

Thanks!
