How difficult is that to change? I can't even lay eyes on it so I'm not sure exactly where or how it attaches. Does it thread into the back of the cylinder head? I have tried to see it from the top but there is very little room between the back of the cylinder head and the firewall and even with my head pressed up against the bottom of the open hood I can't get my head far enough back in the engine compartment to see it. Should I remove the hood? I have tried to see it from the bottom as well but there is too much in the way.
