Thermostat Replacement on the 5.0?

[WhiteLimited]

I searched and came up empty handed, if I over looked it feel free to link me on here and then close the thread but if not can someone help me? From what I understand its easier on the 4.0 then the 5.0...I really have no clue, so any help would be great and pictures as well. Thank You Cheers!

Be careful .. someone here ended up breaking a bolt on the 5.0. It happened recently.

Yeh me lol, very common problem on Fords, the bolts holding the t-stat case to the intake manifold seem to seize a lot. Mine snapped, it was seized bad. Took 4 hours of heat and slow drilling to remove at friends shop, including a couple days of penetrating oil sitting. If you attempt it yourself, you'll have to try a combo of ratchets and extensions, as the casing is in such a tight area there isn't a lot of room, my smaller ratchets would fit in but not strong enough for how bad the bolts were seized, my thick craftsman with an extension worked....and snapped the bolt in the process.

Replacing the t-stat is easy though, once the case is opened, just pop it in, but make sure in the same position as the factory one (some will put it in reverse etc). I used a Motorad Fail Safe and drilled two small bleeder holes in it.

Needless to say, another good reason to use anti-seize when putting bolts back on an engine. Now if only the factory had done that......

My friend and I both said we don't think Ford uses anti-seize on almost any of their bolts. When I've done some other work or on other Ford trucks, their always the ones that give me a ***** of a time with bolts. One of the track cars we sold was a Porsche with 130K miles, and, on some stuff that was original, had no trouble with any of the bolts etc. I'll get a pic of the bolt later as I still have the piece on my desk.

But wouldn't using anti-seize on ALL the bolts make them prone to not stay tight and perhaps work themselves loose?

I mean, aren't there bolts that you would not want to use anti-seize on? perhaps the bolts bolting the head to the engine?

Never had that happen, you don't load the whole bolt with it. The Porsche had 130K with about 60K of that in hard track use, never had a bolt come undone or loose to where something would have failed, as long as its tight and torqued correctly you should be fine. Some bolts you may not want to, but definitely the t-stat bolts, steel bolt + aluminum heads = guarantee seized bolt

You need to use some common sense on when to use anti-seize. I wouldn't use it on head bolts which are very torgue specific, but definitely use it on Tstat bolts and spark plugs.
