We are trying to remove the heads on my car.

For people who have taken their heads off, how the heck did you get this off!

 

I was actually just going to post up about the technique I used which took only about 10 minutes to get them both off.

Take a box wrench w/ the closed side on the nut so its sticking up in the air, then I took a 5lb mallet and wacked the wrench a couple times until It cracked the nut. Did that on both nuts and worked like a charm, no extreme force exerted by me to break them. On the driverside one I just had to use a regular box wrench to keep unbolting it. On the passenger side I could get a ratcheting box wrench on it which made it go super fast.

 

What size is the bolt?

 

I don't remember just try some box wrenches until one is real snug it should fit real snug. I am pretty sure it was a metric but not positive.

 

15mm

 

yes 15mm and also u better buy new seals and bonjoe bolts at the dealer because when u get them back on and u see it leak back there u will be very mad lol. They are fairley cheap at the dealer dont half A@@ it and make sure not to strip the threads tighting them back on

 

Or just get a partner and pull the heads with it still attached.

 

Look at your seals when you pull them, if they arn't cracked you can probably re-use them.

 

I used a 15mm rachet wrench and a lot of thrust haha...

 

I had to end up cutting mine off because after using the box end wrench and beating on it with every thing I could throw at it. I even used PB Blasting on them and let it soak on them for 3 days spraying them a couple of times. I went to the junk yard and got a another steam pipe off a buick roadmaster for $5 GM dealership was about $80. For some reason that one come right off I don't know if was because of the steal heads or not.
