ok, the thermostat is new, the water pump does not leak, the radiator is new, the engine coolant sensor is new, anti-freeze is not missing, and the fans work. i recently changed a fuse that made the fans not turn on, so now the fans turn on at approx. 230 degrees, which my car did not do before. it never went over the normal temp(190). why is it going over now?

I've seen a case where the fan was installed backwards and the fan was blowing air the wrong way. I've also seen thermostats installed backwards. Let's assume that is not the case.

It seems like you've done everything. It maybe that you have corrosion build up that is blocking the proper flow of coolant. Every coolant company makes coolant flushing kit. It basically "washes" away the corrosion build up. But be careful. I buddy used one of these and his cooling system leaked like Swiss cheese. Apparently it was the corrosion that was holding back the leaks.
Just go to a auto parts dealer and ask for cooling system flush. If you just ask to flush your system, they will just replace the coolant. You need to run a coolant system flush that washes away the corrosion build up.
If this doesn't do and you've replace the thermostat yourself, try removing the thermostat. Most of the time, during the summer you don't need a thermostat. If running without a thermostat solves the problem, then you probably (a) installed it backwards (b) installed a wrong temp thermostat.

its possible the fins on the water pump are worn a little and that will cause one to heat up a little,either that or the radiator may be getting stopped up on it,you might want to try flushing it out,to see if that helps it,that's way too hot for any engine to run at,for any length of time,make sure the fan is coming on when it should,it should be coming on, at or around 195 degrees at the most,if not there is a problem with the circulation of the coolant in it,good luck with it.,,i see my admirer is back again,don't pay any attention to them,they,ll go away.

Check to see if the thermostat is opening up & allowing the coolant to circulate. 230 degrees sounds too hot. Why do the fans wait until you reach 230 degrees before coming on?

you can try flushing the radiator - it may have debris built up in it, hurting the coolant flow.
I would try removing the thermostat and not replacing it first. But on newer cars with all the fancy computers, I don't know how they would react while the car is warming up. However, if the car does not overheat, then it could be that the new thermostat is also bad. It happens.

May be worn out water pump impeller.
An impeller is a rotating component of a pump, usually made of iron, steel, aluminum or plastic, which transfers energy from the motor that drives the pump to the fluid being pumped by forcing the fluid outwards from the centre of rotation. Impellers are usually short cylinders with protrusions forming paddles to push the fluid and a splined center to accept a driveshaft.

Who put your thermostat in? Is it in backwards?
