WD40 won't do anything. You could try PB Blaster and some heat to loosen it up. If you have air tools you could also try an air hammer with a flat-faced bit like this: bits to vibrate it to loosen the rust.

Use some good penetrant like Liquid Wrench or PB Blaster. And use a steel chisel and/or hammer.

For those nuts/bolts that are "rustwelded" together, try tightening the fastener to "wake up" those threads before attempting to loosen them...works almost every time. If it doesn't, out comes the Makita with a 4" cut-off wheel...

Good Luck

i used the AGCO panther penetrating oil when i did my timing belt to take off the crank pulley. it works fast, but then again it would have to to penetrate a panther :icon_eek:. WD40 is a water displacement formula that happens to loosen rusty things, its not a penetrating oil by design. a little panther oil, a little heat, a little time, a little more happy.

"AGCO Panther Penetrating Oil (79016936) is designed to help take the bite out of loosening stubborn hardware seizures. This thicker formula includes graphite to lubricate after the propellant has evaporated. The foaming action helps breakdown rust and corrosion plus distribute the graphite for ease in hardware removal."

Just tell the local parts store you need "penetrating oil"; there are a bunch of different brands out there... all of them are way better than WD-40.

And, is the car running right now? If so, there's your heat source. Soak with penetrating oil, wait ten minutes or so, run until it starts to profusely smoke (shouldn't take long at all), and you are all set.
