2003 volvo S60 2.4T
Can't get the bottom bolt out from rear engine mount. Doesn't look corroded on the out side but might be thread locked in (I see two colored marking dots one on the bolt head and one on the support) not sure if those are from volvo or from a earlier replacement of the mount. Took my earthquake xt impact to it and it won't budge. Any helpful suggestions that work? Thanks
