Not all plastic ones are the same, my 98 SW2 never warped or leaked with over 215K miles on it.

At least it's just a cover and doesn't cause engine failure. Ford's "better idea" was bolting a plastic thermostat housing directly to the engine block and flowing hot, pressurized coolant thru it! We had to replace that stupid thing on my daughter's Focus three times in six years!!

Been there, done that on my son's Explorer. Not to mention the plastic "diverter" or whatever it's called fail in the heater hose on the 4.0.

But ... GM also used plastic fittings in their coolant lines at the block. I don't remember the exact configuration, but I had to replace one on the brother-in-law's Bonneville that was a common failure causing the coolant to pour out.

I wonder if Ford tried to patent theirs.

I think this has to do with not allowing to overheat. I have a 2000 that I promptly replaced the radiator when it first showed signs of leaking. I tend to check the coolant whenever I check oil. I also replaced the cam cover gasket when oil showed up in plug 1. It doesn't appear to be warped, and there's no sign of leaking on visual/blotting inspection.

Either way, I'd much prefer an aluminum valve cover if we could get one for 3rd generation.
