Random Overheating

Anybody else have the 3.8 NA and have issues with random overheating. It'll get hot then I'll let it cool down and its fine. Already replaced the thermostat and its good on fluids

Hate to ask this, but have you checked to see if the head gasket is leaking? When does it overheat?

Why do the 3.8's have such a big problem with blowing head gaskets?

Combination of poor gasket material and bi-metal erosion. The 96/97's got multi-layered steel head gaskets instead of the composite paper gaskets that the 89-95's had. However sources claim that they are all prone to erosion due to electrolysis caused by broken down coolant carrying a positive charge, basically unavoidable due to aluminum heads on an iron block. As stated MLS gaskets are better equipped to handle the difference in expanding and contracting between to unlike metals. Obviously all bets are off as soon as the engine is overheated in either case or with electrolysis or rust caused by improperly maintained coolant or a defective cooling system.

Check if you are losing coolant. Check your oil and coolant for milky color in the oil or floating oil / oil in the radiator fluid.

I found my heads where leaking by pulling all my plugs and inspecting them for rust in the ignition area. Also if the ceramic around the electrode is an off color from the usual ivory white. One of them smelled like gas becasue it fouled out and was no longer firing. See my post here.

But if none of the above is present, try these: If it is the original radiator, look at replacing it. Also, your water pump could be going, look for seeping under the pump where the seep hole is. I ended up replacing my t-stat, then the hoses and then water pump. I was still over heating and it turned out to be the radiator was just old and not cooling anymore. All of these parts can be checked before replacing. Do some research on how to test them before replacing them.

My engine was rebuilt at around 140,000 miles with new gaskets and timing chain/ tensioners. It should last a while if I keep changing the oil every 3,000 miles and flushing the coolant every six months right? Right now my engine is at 200,000 mi.

89-95 once a year or every 30,000

96-97 once every 2 years or 60,000

with grean coolant or prestone

That's my recommendation anyway.

That's why I included a time as well. As with any interval it's a whichever comes first type situation.

I know I need a new water pump so I'm hoping that fixes the issue

Well, Like I said... the system is pretty symple... T-Stat, water pump and radiator. But check to see if you are leaking collant on the block anywhere as well.

But of the pump is going, they tend to just go and not do a random crapping out, but it could be possible. I suspect you have blockage somewhere that keeps blocking the flow of coolant every so often. Like I said earlier, mine was doing the same thing until I replaced all three, T-Stat, pump and radiator.

Good luck.

No idea on the mileage. ODO didn't work when I bought it. I did the thermostat a couple weeks ago. Wanna do the water pump and new hoses soon
