Hello,
I was replacing my water pump today and on the top ports the coolant was more brownish. The bottom ports on each side the coolant is a nice green colour.
Does this mean I need head gaskets or is it worse? Oil on dipstick looks fine.
When I replaced the coolant a couple of months ago I don`t remember seeing anything weird in it.

The coolant is also a brownish colour but I don`t really see oil in nor does it seem to be separating in the jug.

I was replacing the water pump because it was leaking from the weep hole

The engine is a 5.3 with at least 150 k miles on it. I replaced the red/orange coolant with the green one when I swapped the engine in my 1987 Brougham.

Here are two pictures of the ports and the oil on the dipstick.

just found out a couple of threads about dex sludge. That might be the problem since I switched from red to green but did not really do a proper flush.

I'll get the hex keys tomorrow for the plugs on the block. But I am not sure I would be able to remove the one besides the starter because I already tried and rounded it off.

I am hoping to be able to remove all the sludge so it won`t come back.

By the way mods, feel free to move this thread to the GEN III Internal forum.

Thanks

Thanks guys,
The different colors of coolant in the ports and expansion tank made me worry a little.
I`ll flush it as much as I can and refill it.

I was able to remove one of the drain plugs. Took a big breaker bar and a good breakfast. Now I have a nice big allen 1/2 in. socket set
Coolant was a nice green colour so it did mix on that side at least. Good chance it mixed properly on the starter side.
