Went down to the ocean lastnight and the tep shot all the way up on the way on the beach i did get a lil crazy for about a minute then let off on the way back i turned off the overdrive and took it easy still got warm but not hot should i just change the thermostat to a cooler temp or do you guys think i should change the water pump as well?

 

That is weird. I can literally usually climb a mountain (4x4in not casual driving ofc) before I even hit 1/2 way up my temp sensor and that was when my water pump leaked and I was rocking the 195 thermo.
Was it really hot out that day maybe?

If not maybe your coolant is plugged somewhere. Do you know when it was last flushed?

 

You should have left the over drive on, your engine doesn't work as hard when it's on.

You need to diagnose the problem before you start throwing parts at it. Check for proper coolant level. Check your radiator cap. If it allows coolant out to the over flow bottle but won't allow it back into the radiator you'll run hot because your engine will be low on coolant. With the engine cold, start it up and observe when the thermostat opens. If it opens a little before 1/2 way on the temp gauge it's probably fine. Check your fan clutch. Get the engine up to operating temp then shut it off. Your fan clutch ought to be hard to move. If it almost freewheels when the engine is hot you need a new one. If the level is correct, fan clutch, t-stat, and cap are good, you might have a slightly blown head gasket or cracked head. You'll need a block tester to find that problem.

How hard is "hard to move" for the fan clutch?

 

Free-wheeling is bad. If you can hold the fan while the engine is running, that's bad. "Hard" should be more resistance to spin than when it's cold.

Thanks. I'll have to check the comparison.

 

I don't suggest anyone try this method of testing.

 

Neither do I but I have seen some fan clutches so bad that I was able to stop the fan with a bunch of rags. I probably should have stated that because you know some meathead is going to grab the fan of a properly operating fan clutch and end up in the hospital.

Part of me was tempted to try it...
But I'm already positive my fan is working fine from having to pull it on and off so many times :P

 

don't think it's the thermostat, that will cause it to overheat if you give'er or take it easy.
in the old days we would look at a timing issue, retarded timing will cause more overheating the harder you drive it.
since your timing is computer controlled i would think it's a bad sensor giving the wrong info the computer or a bad computer.
