I had a engine code on my car that was for the coolant temp. To low. So I changed out the thermostat, the coolant temp sensor and the coolant level sensor. Now I have a code that is a 0480 that says my coolant fan relay or wiring is faulty. I changed the relay but the fan still doesn't work.
I had originally had a situation where I was losing about a gallon of coolant every three days. So I put some Barr's leak stop in the motor. That I guess is what ruined my sensors. Any ideas how to fix this?

Remove fan connector and get some wires to connet fan directly to battery, if fan does not run then fan is bad, otherwise fan switch, relay or fuse.

Have cooling system pressure tested, replace hoses, radiator or whaterver is causing the leak.
