ELC/Ford Gold Question (crusty stuff in the degas bottle)

[tbisme]

I have had my truck back now for 60 days and have put about 3000mi on the new parts, it is running great but i have seen a crusty whiteish stuff forming on the inside of the degas bottle...... It is only in the first few baffled chambers and not where the coolant is completely covering the walls but more where the air pockets are. I stuck my finger in the bottle and rubbed some off and it felt like clay or putty...? does anyone know what i am looking at? do i need to buy a new bottle and have the system flushed? I just had a new cooler installed and the block drained and flushed with vc-9 by the dealer when they were in there, do you think it is having issues- by my TSX temps seem fine - maybe flush and refill with some ELC, or just change my coolant filter and keep on trucking I wish i knew what this stuff was.

I have spent about 6500.00 on the girl in the last couple of months, thought i had all the stuff fixed, although she is not showing any new issues but this, it does concern me at this point.

Thanks in advance for your input.

I would change the coolant filter. Cut it open and see whats inside. Might just be stuff still circulating around from the flush.

All right, I will spring for some ELC and change the filter, do you think i need to flush with vc-9 again or just drain and refill.... and try to clean the degas or just get a new one? I see reason for concern if the residue is all over the engine/rad/cooler/coolant surface... or hope it is just in the degas bottle refining in the vapor.

I would pull the thermostat and flush thoroughly. No need for VC-9. That is for removing iron scale (rust) from internal passages. You may want to run some Fleetrite Restore through it as that is meant to clear silicate buildup. I would thake the degass bottle off and see If I could clean it up off of the truck. Maybe some Greased Lightning and a bottle brush that you can bend to get to the various areas inside the bottle.
