coolant flush
#1
#3
Roughly 2/3 of the coolant is in the radiator. The easiest service is to open the drain **** on the radiator and drain it completely, it takes 10 minutes or so. 2 Gallons will empty. Refill the radiator with 2 gallons of coolant of your choice. To keep it simple I use the 50/50 premix, usually SuperTech brand and perform the service every 30K. At around $5 a gallon I do this service for a total of $10. You certainly can buy a gallon of Motorcraft coolant and mix it yourself with a gallon of distilled water. As long as you do reasonable drain/fills I see no need to flush the system. However, if the truck had high miles with no service in the past I would take it to the dealer and have a flush done.

truck has 164k and ive had it for the last 3yrs and 34k of that. i dont know the service history. i know that it hasnt overheated int he past but it does take a while to get warm in the mornings since it is cooler if not cold every morning. id rather have someone else do it due to disposal but thought id ask if it was terribly simple. i heard its like 60 bucks to have it flushed and refilled. does that sound right?

Last thermostat i replaced was on a 1976 360 in my other f150. it cost like 2 dollars and was simple to replace. Are these much more complicated. i havent had to do any work on this truck so Im feeling a little undereducated here. would it be expensive to do while the flush is being done?

360 in an F-150?
Anyway, no they are not expensive and is just as easy to do, if not easier, just follow the upper hose from the radiator to the thermostat housing and there it is, two bolts later (10mm if I remember correctly and they should be tourqued to specs.) and you are done. The only thing different is the gasket, which is now an "O" ring that sits between the t-stat and the housing. If the coolant is looking nasty, you should have it flushed first, if it's really nasty have it done again in a couple weeks then change it. If the coolant looks descent still, change the t-stat first and all should be good. If you have it done at the time of the flush it will cost more because of labor, have them quote you a price and decide then. Good luck

Good luck w/ your search. Interview some techs, It's a good way to get a feel for their attitude toward their work.

What kind of coolant??
Why we're on the subject, what kind of coolant? I've got an 04' Lariat 5.4. I've heard green, gold, can't mix this with that, so on.... I've got 47K mi and still running on the factory stuff which I think is gold or yellow. Any suggestions? Also, I think my 5.4 holds about 5 gal total?

i had a 76 f-100.. my brother had a 78 f-150. mine had the 360 in it.. nice engine. the only thing i hated about it was it had a rocker arm assembly on it, instead of adjustable rockers.
i found out the hard way how to shim it up when i put an Erson cam in it, and locked it down... held all the valves open. got it shimmed up, and it ran like a beast.. untill graduation night.. i came sliding around a corner, and floored it, while keeping it in first.. bent 6 push rods.. one was in the shape of a question mark..
i finally sold it a couple years ago, and that engine was still going strong.
i cant wait till i can fix up my late grandfathers 71 f-100.. he bought it the same month i was born. body is in excelent shape. think i just need to replace some front end stuff, and maybee have the engine redone, and the tranny just to be on the safe side.
sorry for the thread hijack.. reading the comment about the 76 360 brought back some memories

You need G-05. Although there are probably others, the only brand that I know of is Zerex (Valvoline) G-05. It's available at most auto parts stores... And the 5.4 takes 21.2 qts of it.
