Can someone tell me how to access this bolt in order to stop a coolant leak. I have the pic of the leak in my earlier post. The bolt tightens the heater inlet pipe. Thanks

Hard to tell in the pic, but if that's the pipe I'm thinking of, there's a o-ring on the neck of the pipe to seal it in the intake. That may need replaced as well.

 

That is the pipe, but what is the easiest way to access this bolt?

 

Take off the Alternator. If the o-ring needs to be replaced then that is the best way to get to it.

Just disconnect the battery, remove the engine fan, Take off the engine belt, remove the 2 bolts holding the alternator, pry the alternator loose and disconnect the power and ground wire from the back.

 

If there is a leak coming from there, chances are you will need to replace that O-ring... Tightening that bolt will likely not resolve a leak, it simply holds the tube in the hole under pressure to keep the O-ring far enough in the hole to maintain good contact with the walls of the hole...

 

Got it. Thanks to all
