Coolant Filter Question

[Donnie1]

Last weekend I did the EGR delete, oil cooler replacement, HPOP screen, 6.4 Banjo Bolts and the blue spring mod.

Yesterday I put in the Sinister Coolant filter setup.

This morning I was headed out the road running about 70 mph when I looked in the rearview and it looked like I had just blown motor coming out of turn 4 at Talledega. My temps were good (180's). I pulled over and it looked like coolant was coming out of the top of the bottle.

I shut off the valves (valve handles up) to the coolant filter and drove on a few miles. All was well the rest of the day. I'm pretty sure we had the coolant bottle overserviced because it was just below the top of the bottle.

My question is, would the bottle being overserviced cause it to do that?

Also, the ball valves on the sinister kit are open if the valve is inline with the hose correct?

I did not have instructions with the coolant filter as I bought it used but new.

Any help would be appreciated.

If the valves have not been messed with then yes when the handle is in line with the valve it is open. I have the sinister kit on mine and that was how it came set up.

I was thinking the same thing as well. Just wanted some reassurance.

Didn't know either that if the valves were closed would that cause the coolant to back up in the bottle. Don't think it would but you never know. I have the valves closed for now but will reopen tomorrow. I think it was just coincidence that it happened after installing the filter.

Where did you connect the lines in?

If the valves are closed the coolant should just by-pass. It works on the same principle as the by-pass oil filter only samples a percentage. As far as being over serviced it could have something to do with coolant coming out of the cap. Check the cap and make sure its still good.

Front side of the heater valve and the degas line.

I'm going to pick up a new cap tomorrow just to be on the safe side.

Yes, if the valves are in line with the fitting then their open. If the coolant level was up much higher then the lowest level mark on the degas bottle then it was overfilled. It probably just pushed out the overfilled coolant and ran onto the exhaust manifold.

Not sure what year truck you have but the degas bottle max level is now at the lowest mark on the side of the bottle. Ford came out with a sticker that was placed on the bottle. For some reason Ford never changed the level markings. Even a new replacement degas bottle still has the sticker on the side of it.

Your connection from the filter to the degas bottle is on the line from the rad to the degas bottle and not the line that comes from near the EGR cooler to the degas bottle, correct?
