diesel fuel in coolant system

[Boomer998]

Wondering if anyone has had this problem. I have a 2002 7.3 L excursion, smells like diesel fuel, and seems to be leaking into radiator overflow. What's the fix and how much?

The problem is likely a fuel injector cup in one of the heads. This is a brass cup that is pressed into the head and the injector sits in the cup. If the cup leaks, fuel can enter the cooling system. Not sure about the price but it will be expensive. Ususally the head has to be removed in order to prevent metal from entering the engine as a large tap is used to extract the cup.

from what I have read I aggree with the diagnosis, I think if its front 2 injectors it can be fixed in vehicle. keep your fingers crossed.
good luck.

check the nitrate levels in the antifreeze, might have caused it "cavitation"

yea like they have said it is usually the injector cups. It is possible to do all 8 with out pulling the heads. just takes the right tool. where are you located?

[rj2000psd]

you can do all 8 in the vehicle, but the back ones on each side are a b%^*h.
and hope they don't spin around in there, that makes it a real B*&^h to get out.
