Fel-ProES 72434 Engine Cylinder Head Bolt Set for Toyota Corolla

These are one-time use bolts, meaning that you should replace them with new ones when changing your head gasket - so that's what I did! These worked perfectly and I had no issues installing whatsoever. *Note: There is a specific torque and procedure for varying Toyota vehicles i.e. for our 2010 Prius it was the 90 degree, then 45 degree in the rotating X-Pattern so you don't over-torque one side and warp anything - do your research beforehand to ensure you know how to do that properly on your specific model to avoid issues.

Perfect fit for my 2012 Prius.

These worked great for my head gasket job. None of mine were bent like other posters were saying. Just remember to blow out each hole with compressed air before torquing these down. Any coolant or oil in there will give you a bad day!

I’m not sure my mechanic installed them so I would say it’s a good product

After setting all of my bolts, I started hand threading into their seating. One of the bolts was impeded before reaching its depth. It would not turn with only hand pressure and I wasn't about to force it in for fear of cross-threasing.In backing it out, I noticed the nick circled in the photo. I reapplied the bolt and, sure enough, it started catching at the point. Inserting a different bolt with no visible defects was successful, so it is definitely a problem with this bolt.I had planned on completing this project by tomorrow, but now will have to try to find another set of boots from a nearby store and spend additional money to overcome these defective bolts. I hope I can find a way to get a refund for these as I'm very disappointed in the Fel-Pro's quality assurance and my ruined plans to get this car up and running this weekend.

Needed for a Gen 3 Prius head gasket job. With what else was wrong in the disassembly process, I wanted all new bolts. These bolts arrived quickly, straight (nothing bent), and were extremely easy to assemble. Wish they came with the washers but I reused those. Zero issues and made bolting the head back on a cinch (all other work considered)

Of course when removing head bolts they need to be replaced. The Fel-Pro brand was recommended to me as a good option over OEM. They worked perfectly, and more importantly arrived quickly. Thank you Amazon I have a car again....lol

The only reason I can't give these 5 stars is because one was bent and caused some issues upon head re-installation. The rest were no issue. I've seen worse bolts. Only have 3.000 miles on the car since rebuild but so far so good.
