when i get in my car and turn the key on then right back off the cooling fan comes on now ive done replace the two sensors in the head but not the ones in the therastat housing or the one in the return hose now could they both be bad or just one and which one is it and help ??????? also the car is not running or have been running for this to happen

 

Use a Multimeter to measure the OHMs in them.

 

your post is very unclear and hard to follow, but i think i understand that your fan is staying on??? try pulling out the relay. they sometimes stick. my 94 accord fan relay stuck on and ran the fan til the battery died.
