Broken exhaust manifold bolt

reguarding broken exhaust bolts

in regards to broken exhaust bolts there is a simple fix available that Ive used myself on my suburban over a year ago that to this day has not failed. the part is the "Origional KAP" on the website www.kralautoparts.com one of the bolts in the other corner i was able to extract and replace at the time but just noticed recently that it had broke so i actually plan to order another bracket, they seem to apply adequate pressure while allowing the manifold to expand and contract which is what i believe is breaking these bolts off. enjoy your results as i have

There is a great product used by the aircraft repair industry in loosening frozen exhaust studs in aluminum heads called Aero Kroil. Its the best penetrating oil I have found. Hilco Lube is also good.
