Heat and Head gaskets
I search on the forum and couldn't find anything pertaining to this so I thought I would ask....Is it true that the main reason the head gaskets fail is because of coolant temp and pressure? I was thinking that if a larger radiator was installed , the engine would run cooler and in turn colder coolant means less pressure in the cooling system and theoretically, fewer head gasket problems....Also, maybe this theory is wrong when you take into account the egr. I have a 2003 6.0l and would like to do some preventative maintenance to ensure I don't have problems down the road. I appreciate everyones comments on this and tell me if I am wrong. Thanks!

I think it's the head bolts stretching (most likely if using a tuner, but some have happen stock), which allows cylinder pressure into the cooling system (and the resulting puking of coolant). I believe sticking turbo vanes can also cause this, but usually the intercooler line blows off if turbo pressure gets too high. If you run your truck hard occasionally, the turbo vane problem may be eliminated...
for preventative tips: You could add a coolant filter. Theory is the leftover sand (and other crud) from the casting process can clog the EGR cooler, which then causes the oil/coolant cooler to fail. Likely the next thing I'll do to mine...
Also change the oil/filter at least every 5k miles

So, would I be better off speding my money on a larger intercooler than a rad?
So far my truck is stock, and I only tow 50 % of the time. I'm not into street racing, but like power when I am towing

Neither will help.
Your best bet to be safe from HG failure is to not mess with it, although they still blow stock. It's just a product of torque to yeild bolts and not a whole lot of them.
If you really wanted to be preventative, you could replace the bolts with head studs, but I would only do that if I had to because the HGs were already blown.

Just remember that more power increases the likelyhood of exposing a weak spot and most seem to find that to be the head bolts...
good luck to you with whatever you decide to do
