My son has a 98 camry. He recently noticed that the temp guage was slow to come up to middle (usual running temp) and would drop down when going down a hill. He also believes he can smell fumes or something different in the cabin. He believes the engine gets hotter than usual but not being mechanically minded could just be imagining the fumes and excessive heat.
The slow rising temp gauge points to a thermostat which has failed and stuck open. This is easy to replace.
At the same time the gauge will tell you if the car is overheating.
Is it losing coolant at all? A hot smell can result from leaking coolant getting on the exhaust manifold.
The smell can also result when leaking engine oil gets onto the exhaust. Camrys of that era had several characteristic oil leaks
- from the rear of the cam cover, especially on a V6
-from the distributor shaft o-ring
-from the oil filter-to-engine block mounting adapter (if fitted)

Have your mechanic check the timing belt marks and the condition of the belt itself. If the cam is retarded a 1/2 tooth due to age, this will create this problem as well. Have him also check for any vacuum leaks at the intake.

The Temp gauge should read in the middle of the gauge at operating temperature. This is normal. The radiator fan should come on after idling (not driving) for 20 minutes. The fan should also come on when you turn on the AC. Are you experiencing overheat problems?
Please reply if you have overheating issues.

Switch ig. on, ground the sender unit wire for about 3 seconds see if the temp. gauge moves, if so change sender unit, if not then it is a faulty gauge reader.

yes. it could be the switch, or it could be the blender door that is stuck.
