I hope that the shop is going by the service information available for this car, instead of doing it without instructions.
The 2 bolts without the captured washers have their discrete washers installed with the bevelled-side up and the torques are different than the other 8 bolts with the captured washers.
Torque head bolts from the middle towards the ends. See attached.
the garage found some studs but they looks different.
here I will show a photo with my engine studsand the new studs
the new ones in the left side have the head studs little smaller. Are they suitable in my car?
I add the new studs box with part number.
Right now I did stop the work because I'm looking for the same studs like mine and it's going be hard because even stellantis spares store don't have them e doesn't order anymore.
The Chrysler 2.4L is a different part number (14-10383-01). I don't know what is different about them, but there is a different part number & this: "Each manufacturer configured their variants of the initial design differently based on their engineering needs and standards, so consumers may experience very different power, fuel efficiency, and "feel" from each manufacturer".
I would want the 14-10383-01.
Mitsubishi ones have head bolt shorter compared to Chrysler ones, you may see yellow for Mitsubishi and red for Chrysler. The thread in Mitsubishi is shorter than Chrysler thread as you can see in yellow and red arrow in the photos.
The only doubt is that Mitsubishi studs are not suitable in Chrysler head.😔
Yes, you're are right, that is why I did stopped the work, I'm not feel safer.
The guys in the parts shop ordered another type from V-R but i don't know the code number. I'll see next Friday.
With your Victor- Reinz code part number, i found many sellers on the web. 😀
In the description they said are for Hyundai and Kia but looks identical to Chrysler's ones. 👍
In the garage finally they are going to assembly the head ad all related, with right spare parts, like the studs.
I'm looking at the thermostat. Would be a good idea to put a new ones, after 10 years?
Yes looks some dirty rusty color.
In the garage they also found in the head a small casting cap with a corrosion hole. From there the cooling water had a small leak in the timing chain side.
They put a new one.
Is strange that corrosion because in the last ten year i did change che antifreeze a couple of time. 🤔
It is important to use a HOAT (orange) antifreeze and distilled (soft) water.
The HOAT should meet Chrysler MS-9769. MS=material standards.
In 2013, Chrysler began using an OAT (purple) coolant. It would say so on the coolant reservoir cap.
Do not mix coolant types.
