was changing thermostat when i found a big bolt stickingstraight out the left side. goes thru what looks like mount block 4 all the belts & stuff(sorry for getting so technical). sits below & 2 right of windshield washer res. also in last day or so, developed a BAD sounding noise, like marbles in a can, but it doesnt seem 2b coming from inside motor.....could this bolt b related 2 that, or is it more likely a pulley or belt or something.....so like i said....this idiot needs some help..thanks-mike

 

try and take a pics, i really dont get where you are desribing!!!

 

is the head of the bolt require a torx bit to tighten it?? bc the only bolt i can think of is a thru bolt and if it is try to tighten it with a t-55 torx bit...
