Didn’t see any mention of the cabin dome light bulb. Has anyone found a 24V part number for that one or is everyone just rolling around in the dark like me lol?
Installed the new cylinder head. Then found out I needed a new fuel prime pump as well. Got that and replaced it. Started up and I’ve been pleased to see that the temps are back to normal! Now on to the next fix…
Yeah I really didn’t want to pay for a new cylinder head, but that was the last thing that it could have been. I’ll be sure to keep this one nice and cool!
4 Wheel Auto has been a great help for parts!! The head he sold me is an OE refurbished. It will be easy to tell if it’s not.
The machine shop I took it to said some of the cracks were too deep to repair. There is a crack in between the intake and exhaust valves on each cylinder, and each pre-combustion chamber seat has two cracks except cylinder four which has three.
I bought a set of new pre cups from Radd Cruisers...
All of those changes were made after the turbo was installed. I was absolutely loosing coolant out of the overflow, every time I drove the truck. I was swapping other components in different configurations because I was trying to avoid removing the cylinder head. Wishful thinking. As far as the...
As I wrote in the first post, the radiator has been fully rebuilt. The thermostat has been replaced, the water pump works and I have a new one as well, and before I changed the mechanical fan, the fan clutch had good viscous fluid in it. At this point, there isn’t anything left but the cracked...
While I’m sure all of that would help a little, I went ahead and removed the cylinder head and sent it off to be machined and magnafluxed. Turns out there are 13 cracks in the cylinder head. I don’t think any amount of air moving through the radiator or intercooler will help with that many cracks.
It’s the stock radiator. I’m surprised no one else said anything, lol. I had the casting moved to the other side in an effort to ensure coolant is flowing through the entire radiator and not just part of it. May sound silly, but I did see a slight improvement, even though it still overheats.
