Water flow from Thermostat Bore F150TXRD

[pstephens46]

There was discussion on another thread regarding water flow through the thermostat bore under certain conditions. A few videos.....

First: with just the flush port connected and NOT running. Thermostat obviously removed.

Second: Flush port and muffs connected. No stat and not running.

Third: Running with stat removed

ID of flush port line is 6mm. Had to remove about an inch of hose to get back to original size.

About a quarter of an inch for the non-metric folks. Quite small actually. Hard to even blow through let alone flow much water.

How about a half inch ID hose going directly to the engine side of the thermostat for a top down high flow flush?

Nice!

I particularly liked seeing the tiny jets spurting from the 'stat bleeders in Video 1.

Tiny "flow" but shows that the cavity behind was filled and pressurized.



IMO there is a market opportunity for some seriously robust dual-feed muffs - with a powerful clamping action.

This is what I do to get my (best quality available dual muffs) to work on the F225:

I had to set up a YouTube account for the first time today. I was trying to upload and was getting an error message that I needed to choose a name. My GD name is part of the Google acct. Nope. need another. So I finally figured out where I needed to be to make the change. I live in Richmond Hill......

I liked the idea of a composite thermostat housing. Or at least make it replaceable.

Excellent videos - thanks for taking the time to experiment and record these 3 scenarios.

I remain interested in seeing if a hole or two drilled into the T-Stat face will help FW and Air escape through the highest T-stat bore on the block.

It seems like it can't really hurt anything since the T-stat will be wide open at operating temperatures - where - you could have 10 holes and it won't matter.
The engine might run a little cooler at *****ing speeds due to the leakage of salt water. But, I can't think of why that would be much of a problem.

you failed to post any words with that

[boscoe99]

Are words needed? I did type the words "air bleeds" in the reason that I edited it. Look below the bottom of the photo.

"Breeders".

Who makes the best flushing attachment for a '05 F225? attachment.php?attachmentid=316493&stc=1&d=1364639549.jpg

Those bodies look like twin sisters.

Solid flush attachment
