06 losing coolant, high ECT then it drops

[craig031600]

ok, so heres what i have going on....this past summer i wanted to do a coolant flush just because. Along with the coolant flush i replaced the water pump, upper and lower radiator hoses, degas bottle and cap, and heater core. Had no problems with the truck just wanted to get rid of the ford coolant and replace parts associated with the coolant. Forgot to mention i have a coolant filtration kit. I drove the truck on approx 1800 miles in a week. I have noticed that when i start the truck and at times throughout the day it will blow white smoke out the exhaust. I have no problems with the driveability of the truck at all. a few times on my road trip the ECT temp on my Edge insight was over 230 degrees and reached up to 245. i was driving in a snow storm so i couldnt just hit the breaks and pull off the side of the road. After a few seconds it would gradually make its way back to normal (195-205ish). The fan does work, i can hear it kick on at about 215 degrees. When i made it home i had to add slightly over a gallon of coolant. Im not dripping coolant anywhere and it has me stumped. Forgot to mention the truck IS studed and has an EGR delete. Any insight or opinions would be greatly appreciated. I dont want to mess up my truck or anything as i have a lot of money wrapped up in it. Thanks!

Bad water pump, leaking, and or radiator needs to be checked for blockage?

You say you were in a snow storm, if the snow packed up in the radiator and restricted air flow you would overheat even with the fan comeing on as it should. No air to suck thru the radiator. No heat exchange.

At 240 deg. the glycol itself begins to boil, so you boiled and vented out your missing gallon.

im back home in NC (no snow storm) and i drove about 75 miles today around town and had to put in about a little bit (1/4 gallon or so). i feel as though im losing it somehow because i have no leaks but the coolant slowly goes down in the degas bottle. The water pump is new so i dont see that being the issue. The radiator looks to be stock but is not leaking anywhere.

I'm having the same problem
Degas bottle cracked so I replaced it but I filled it up with distilled water no coolant and I would always had to add water so when it got low I just added distilled water well one day I went to work and the heater started to blow cold air so I checked the coolant and it was really low and and the plastic end caps on my radiator were leaking I changed the radiator and used proper Coolant mix and I still have the same problem what now water pump? Or cap

Also egr delete,studded,
edge insight and sct tunning

[craig031600]

Sounds like we have a similar problem...i also have an egr delete , studs, edge insight, and sct tuning. Its bugging me that i cant figure this out and i have no leaks anywhere. we'll see if i have to add anymore coolant and the end of the day....more than likely i will

What level in the degas bottle are you useing for full. The new full is 3/8" below the molded low mark on the bottle.

You definately overheated it during the snow episode you probably have a small crack in the head or a gasket leaking. It is small enough for the engine to still burn it. You may also have a bad cap.

[craig031600]

i fill it i'd say about a 1/2" below the full mark on the degas bottle. i dont remember seeing a "low" mark in the degas bottle but ill go look at it again and see if i can see it. Im really hoping i dont have a crack in the head or the head gasket leaking. The truck has NEVER given me any problems before.
