I know this is not a popular topic as I found only one thread in almost 3,000 and it simply stated that doing it is a PITA. However, I am determined, and in the absence of a Haynes Manual am turning to the Forum for help.
I am of the understanding that there are 2 thermostats in the cooling system, and that they may have 2 different temperature ratings. Where they are located, what additional parts / tools I may need to replace them is my biggest question. As I use my truck for work, I cannot afford to have it down while I hunt for parts, etc.
If you could please provide photos, they would help me immensely as I am not wholly familiar with the lingo used in this forum.
Thank you, Senix. Some helpful tips prior to diving in. I had never considered "one time use" bolts. Any idea what temp the thermostats would be rated for? When I visited the AM supplier, they only had one type listed in their system for this model.
You should also replace the upper hose at the same time. Those are quick disconnect type hoses on there. Orginal ones only had one 0-ring for sealing. New one has two o-rings.
Good call on the upper rad hose! I was just on a 1000 mile trip and mine started leaking antifreeze everywhere.Got a new one replaced(Not under 36000 mile warranty dammit) The service Mgr advised me of the new 2 oring hose assy,said he hasn't seen one of the new hoses leak yet but has had alot of the other ones go bad.
I already replaced the upper hose. The gasket melted and started to leak while I was traveling through phoenix in 100+F while towing my travel trailer. Only thing to go wrong on the truck during a 16,000 mile road trip!
Does anyone know where the thermostats are located, and how to replace them? Again, pictures would be appreciated.
I also had the upper hose leak(seep) on mine. Only noticed it when I went under the truck to look. Also found a new tsb ford has about hyperextended thermostats. They claim that builds up pressure and causes the radiator to leak. Probably the answer to all of our radiator problems.
I removed the upper radiator hose and EGR cooler to get them. If I remember right the T-Stats are shaped differently so that you can't get them mixed up.
For sure an SOB, took me 5 hrs and 3 or 4 bloody knuckles.
