Well my car had been idlin really weird today, and I looked under my car an there was one bold barly holding it on, the other one completly backed out.. My question is are the two bolts the same size? It has been a long time since I had installed it, an can't remember if they were the same size... Also one of the bolts I had to keep on tighten it up an I guess it had a while since I checked last.. But once I get the bolt back in should I put some thread lock on it to keep it from backing out, or will this cause problems in the future... One more thing I checked all around under the motor and on top to see if there was any damage from driving with it gone and I didn't see anything other then the bypass coolant hose looks like it had been pinched by the motor and cut into it just a hair.... Anyways any help would be appricated.
