Upcoming coolant flush to ELC

hey guys i am planning on swapping to ELC coolant from internation next week and i have a few questions. I am going to use Restore but am unsure about restore plus because i have heard that what it loosens up could clog the oil and egr cooler.. Another question i have is if i should remove the thermostat or not. Yes removing it will save time but i heard that the engine may not get up to operating temp just sitting there on high idle.

Truck is a 04 F350 crewcab long box dually. The headgaskets, egr cooler and oil cooler were replaced at 177000 km and i know have 221000 km on it.

Thanks so much guys!

Mitch

Either one (silicate goo or rust/scale/etc) has a potential to clog your oil cooler. The purpose of doing these cleaners is to prepare your engine for the new coolant If it does clog the oil cooler it was going to happen sooner or later anyway. If you flush it really good more people have been successful than had problems.

If you take the thermostat out take some cardboard and block of the radiator to get your coolant temps up. There are a number of writeups for flushing your engine. Mine is in the 6.0 tech files section and Nylon also did a nice write up on another method.

In my opinion, do it right or just flush it and put fresh G-05 in it. When your oil cooler clogs then do the full flush and change over.
