Coolant Level Sensor Location?

Hello guys,

Actually I have problem with the water level in the coolant tank, its shows the display warning to check the water lever, however once i check the tank it shows its full , I assume it has some faults with the water level sensor, I wish to know how to replace it and where its located.

Hope someone who faced the same can share me some of his experience.

Regards

Washer fluid level sensor part #2205400045 (for comparison shopping, parts.com $10.64) PM your email address and I will forward WIS for washer reservoir.

I apologize, previous recommendation for “washer fluid” sensor was incorrect. In rereading your original post the water level switch to “coolant” expansion tank (#170 in diagram) is part 22054540024 (for comparison shopping, parts.com $10.92).
