My 2005 KZTE have less power now,than before it had a servive. Then climming a hill the temp go up but on normal road there is no problem only that it feels lazy and need to go to 4 gear offen to keep up my speed. there is no smoke as far as I know.

200- 215 or 190, or even 150 on the oil temp . The water temp runs about 15 degrees less than the oil temp. according to Caterpillar. hope this helps; I think there are many variables- how new/old, etc...

Not sure I am following your story.
Are you saying the transmission is slipping and therefore the RPM is high even tho the road speed is not ?
Or is the transmission not upshifting to the next gear at a normal road speed ?
Is the check engine light on ?

if its not going int o red zone it is normal to get hotter as she climbs hills

I have a 98 punto sporting nd today it started running like it was misfiring but wen i accelerate slow its fine but wen u accelerate as normal it spits and splutters :'( any suggestions??i have change fuel filter nd injectors ????

Hard to say.
Under normal conditions, vent temp should be about 20 or 25 degrees less than outside air temp.
So if outside air temp is 90 degrees and the engine is at idle speed, vent temp would be around 65 or 70. On the road the vent temp could be less than 60 degrees.
If outside air temp is 70 degrees vent temp will be around 40 - 50.

Check for back pressure in the exhaust. A plugged cat will cause the exact symptom you have described.

Fuel pressure Normal range is 35 to 70 PSI. Without the proper fuel pressure needed the vehicle surges and looses power especially goin up hill and at WOT(wide open throttle) . Its a good call if you change full filter your going to any way. you got a surge going on. Also check the airfilter once that plugs up it will also cause the surge. Surges happen when it lacks something so your getting less of some thing

First change your fuel filter. Get good patinum spark plugs and new wires. A cold air intake would help as well.

It sounds normal, but perhaps the radiator is a little small. Make sure the core is clean by blowing it out with compressed air (from the engine side) to clear out bugs and other debris. Make sure the overflow/reserve tank is at the proper level. Check the coolant level in the radiator when engine cold--it should be right at the top of the filler. These are all preventive, not a cure for anything.

Its overheating when you go up long hills because the engine is not getting adaquete air in the system. The radiator is angled to get optimal air a certain way. It may overheat but you shouldn't start seeing smoke.
