I bought a thermostat and had it installed, that did not help the problem. Then I noticed that when you try to bleed the coolant system the water pump is not working at all not sure that is not a fuse for the water pump though and I cannot find the location of these fuses. Please help.

There are two fuses that we need to check. F23 and F02. F02 is for the characteristic Map Thermostat and coolant pump. The F23 is the 12 volt feed for the pump so they both need to be good.

If that is okay, I included a testing for you to run through to see if we can track down the issue. Let me know what you find with this and we can go from there. Thanks
