Ive said it before numerous times,..but for the sake of catching up the one, lonely mis-informed individual that doesn't read my every word.....
The engine will not get hot, and stay hot.
There is a functioning 192 degree t stat in the car, and I've checked it in a pot of boiling water.
Put the car in traffic, stop the airflow through the radiator, and as a result the engine temp rises. Eventually it'll reach about 202,..and the fans come on and it'll cycle between 192, and 202...
But just as soon as the car gets moving and air starts moving through the radiator, it'll drop like a rock. The running temp on the interstate is around 150 degrees...
I know that 150 degrees is actually a bad thing....I know that the engine hasn't reached it's full thermal expansion rate, and things like ring seal, and piston sidewall clearance aren't optimal..
Ford I-6's are notorious for wearing out the #1 cylinder because it runs significantly cooler than the other 5, because in the stock configuration....the water pump is directly in front of that cylinder.
I am not using a stock water pump,..I have three hoses distributing water to the block alternately.
It looks like this:
it's the hose that's obscured that I'm considering here...the one at the front of the engine going to a plate that used to have a water pump bolted there..
This shiny one..
Even though the T stat would typically be closed,and shouldn't allow any more water into the engine until it opens up...I'm thinking this has to be the source of my issue. Because of the fact that I have an electric WP putting water into that hole ( (and the other two in the side of the block)
The water temp senders that are about 8" immediately above that water hose MUST be seeing that cold water. That cold water is somehow circulating, elsewise the water would get hot in the engine...
What If I remove and block the short hose that's going to the WP block off plate?
Not as easy as it sounds...That's a -12 braided hose that I jammed over a nipple that's threaded into that block off plate
I probably won't be able to get it to slide off. MOF, I'll probably have to make an entirely different block off plate because of that. I'll also have to buy a -12 cap to "plug" that hose nipple where the hose end is presently screwed on.
Needless to say, that if I go through all of that and the engine doesn't get hot...and I remove all of this stuff..
I'm gonna get hot.
How is water recirculating currently? Maybe it isn't, and because the senders are so close to the water source they are constantly getting exposed to the cooler water?
I don't want to chase my tail when there is another way to fix this..
At one time,..I had an output in the MS dedicated to the WP...and was able to tell the pump to turn on and off. I lost that output for some reason in all of the firmware updates that the I've went through..It is also one of the underlying reasons that I want to restore that functionality.
At the same time,..if I do get that running it'll mean that I will be constantly triggering the waterpump in an effort to control that temp based on a set hysteresis in the output settings ( On at this temp,...off at that temp) Once I allow the water temp to rise in the engine hot enough to open the T stat,.I can tell the pump to turn on, flush cool water through the engine, and shut back off after that T stat closes again...
Worried about how quickly that "event" will start reoccuring once the WP is the main player in how to keep my stinkin engine at operating temperature...and whether or not constantly turning the pump on and back off will shorten its lifespan as a result.
