I am trying to replace the radiator on my 1998 Expedition 4 wheel drive and it has an oil cool but my problem is two things I CAN NOT BREAK THE FAN LOOSE.1 PROBLEM IS IT SEEMS THE REPAIR MANUAL SAY IT HAS A LEFT HAND THREAD HOW EVER I WATCH VIDEOS ON U TUBE AND ALL SHOW JUST A REGULAR NUT SO I DON'T KNOW WHICH WAY TO TURN THE NUT. 2 I RENTED THE WRENCH SET FROM ADVANCE AUTO. I COULD NOT GET THOSE TO WORK, ALL PIECES WERE TOO BIG, THE OPEN END WRENCHES WOULD ROUND OFF THE SHOULDERS OF THE NUT AND THE ONE TOO USE TOO HOLD THE WATER PUMP WOULD NOT STAY ON. SO ANY SUGGESTIONS WOULD BE WELCOME. I hope you can understand what I am saying.
