OTCHU

Hello everybody

First, sorry for my english ... gonna try my best ! lol
Second, I know almost nothing about mechanic so understand me please if I have stupid question lol.

This morning after 10 minutes of drive, my explorer start to overheat. The fan was on ... the cooler fluid is little low but not to bad. If the fan turn on, thats mean the temperature sensor is good, right ?
Looks like the cooler fluid doesn't move at all ... does that mean that can be the pump ? How can I check that ? if thats the case, is it hard to replace and do I need special tools for that ?

Thank you very much for any help
Vincent

Your English is excellent . You could check / test thermostat is o.k and opening correctly . If that's all right , try flushing and then bleeding cooling system . Could be other possible causes , i.e possibly partially blocked radiator .
