Just did mine at 147k. Disconnct battery. Remove Air intake and unbolt radiator shroud. Dont have to remove. Disconnct the radiator hose at the radiator and flop it up toward firewall. Un plug and remove three bolts. Will have to turn to remove. If you havent done so it may be a good idea to replace the cerpintine belt. Recommended every 60k. Also did mine for the first time at 147k. Half hour job. I think it was $250 with a $50 core charge.
