The jeep should have 2 coolant sensors, one guage sensor and one switch. Try replacing the other one that you haven't already replaced.

My coolant sensor is bad on 1998 Jeep Grand Cher Laredo TSI V8 5.2 4X4 is flashing in control panel.


Trace the upper radiator hose toward the Grand Cherokee's engine until you reach the metal component connecting the hose to the engine -- this is the thermostat housing. Find the coolant temperature sensor -- the electrical component on the thermostat housing. Press the locking button on the coolant temperature sensor wiring harness and pull the wiring harness from the sensor, then remove sensor it screws out. when putting in new sensor coat the threads with teflon pipe thread tape so there is no leaks.

Warnig light comes on even though coolant level is good


It's very likely you have a bad coolant level sensor.
This sensor is in the coolant reservior. In some cases you may get the same warning if the reservior is overfilled, make sure the level of coolant only goes up to the, " FULL " line on the reservior.

I hope this helps you.

The engine warning light wont go off, (Mazda 6) even after oil, water and coolant have been added. is it time for an oil change?


Yes it is time for an oil filter and oil change specially if there is a lapse of over 10 months or a mileage of more than 5000 miles clocked since the last oil change.

Coolant sensor wiring would be the next place to look. Make sure connector is good, and look for broken wires.
