What is the proper PSI that should be used on the expansion coolant tank cap on the Detroit 8v92
I was thinking 7 to 9. You running a closed system? Give me a serial number and I'll get what the factory specs.
Where is Port Otange FL?
Maybe Port Orange, South Daytona?
8 psi is the number that pops in my head
I have 8v92's TA-DD - 1994. I just had to replace the old cracked caps and found the caps and tank are actually a caterpillar part. The caps only are 3362022. My system indicated 7 psi. New caps are vented but the boat ran at 168 degrees with no issue.
OK checked the caps on both engines they are 7psi. Both are kind of rough and they are not DD. Can I use any type of cap? say from napa etc or do I need to get from DD.
The better part guy (person) at the counter can find the correct cap. There will be two different caps. Go for the closed system. If not already, upgrade your system to a recovery system. Your bilges would welcome it.
