Thanks Mike and Clay,
I am talking about the side cover as I believe Mike is.
I was afraid I might need to remove the alternator, thats why I asked. I will look at it from below and see whether I can see that bolt. I have a 1/2" drive torque wrench which, with my luck, will not go there.
The CD says only: 1. remove hose, 2. remove cover (3 bolts) 3. remove thermostat.
I assume they meant the lower hose, right?
