Review on πŸ”§ Dorman 674-915: Premium Driver Side Exhaust Manifold for Select Jeep Models by Gabriel Salleh

Revainrating 5 out of 5

Quality exhaust manifold budget replacement (driver side)

Great price compared to many, the heat shield is the only place I feel they cut corners on this exhaust manifold but I used it because I worried using his Stock Screen would just add another rattle to my 2010 Jeep Wrangler. Construction was good, nothing special but a great stock replacement for the price and speed of delivery. It wasn't hard to install on my 2010 Jeep Wrangler Sport 2dr, wear gloves (I had to cut myself a few times in hard to reach places) and make sure you used the old exhaust manifold bolt penetrant a few hours earlier (preferably in the evening), you can try to loosen the old bolts and they can snap if they are too tight (space in the engine is tight as you don't want to try to remove the bolt shank from your engine either). On a jeep make sure you have some extensions and at least one swivel/u-bolt bushing. I used 2 swivels and a very small cordless percussion gun to limit the torque, M12 Milwaukee to be exact and different extensions depending on which bolt I loosened. You will need about 20 inches of extension to easily pull out the bolts on the exhaust from under the car. I forgot the exact torque specs I set everything to, but there are good reviews on the internet on how to do it yourself. Don't forget to buy anti-seize as the bolting on the new exhaust manifold accommodates Chrysler's torque specifications. I'm not a mechanic, I just read a lot before doing it myself and abided by the rules since it was my first time changing an exhaust manifold. was careful, did it in 30 degree weather, outdoors, in a sloping driveway, took many breaks and sprayed a lot of penetrating spray at the beginning and it took me 3-4 hours, without experience and only online tutoring would do it take me less time if it wasn't so damn cold than I had to. The old screws were not reused, it was cheap enough to buy a new set right here on Amazon and I wanted to get rid of the old rusty ones to avoid future damage.
