heater / cooler by pass ( pics ) is this okay?

[NovaSS]

here is the oil cooler by passed, should be no problems right ?




heater element by passed. do I need to install the sensor back in this line?? Im not sure what if any input it gives. you can also see the throttle body line by passed.

thats what I did on my car, working so far for a coulpe months probably now, I had the heater just bypassed between the heater hoses at the firewall, thought it would be more reliable with just one hose instead of 3 or 4 hacked together with metal pipes and a plastic coupler.....

that sensor is for the EATC if I'm not mistaken, it has other sensors in the thermostat housing area for the actual engine/computer side of things.......

edit, actually I see u bypassed the oil cooler too, I foget how the coolant flows through the oil cooler area, but I know the heater side of it has coolant comming out of the back head and returning it to the thermostat housing.....I wonder if the coolant flows out of the block into the oil cooler, I would assume so thinking how the coolant system works..... I would just route two seperate hoses, one from the cooler location, one to the heater location, and put them into the thermostat housing where they wind up when its hooked up like the stock hoses....


and I hate to say it, but that upper hose looks nasty, maybe try something like this out

I know your car is real clean and you seem to like good looking work, so you might like this

Ya I know , looks like crap but it was laying around/ free.

I have some stainless elbows left, may just run the line up so I use just a short section of hose of like you pointed out, something a little nicer. May move this universal hose down to the lower lradiator were it cant be seen.

The oil cooler was bypased using the same flow path as the factory, just with out the cooler in the middle

Input for EATC makes sence. I have a complete factory wiring diagram but left it at work this week end

yeah I found my SHo engine manual

it runs how I thought,

your cooling system goes like this

the water pump blows water into the block and heads, where they come into the thermostat housing, where either the thermostat opens and sends the used coolant to the radiator, or it sends it into the bypass pipe and back into the water pump to repeat the process....

both the heater assembly and the oil cooler are basically holes in the block or head that uses the coolant for another purpose, then when its done, sends it to the thermostat housing.....

so if you loop the oil cooler outlet and the heater core outlet, both ends of that hose have coolant wanting to come out of it.... now what could be the downside to that? improper coolant flow maybe, it might work fine though.... the only thing I could think of is the hotter coolant could pool up in those spots, of particular importance would be the rear head that goes to the heater......

the head has two outlets, one goes into the heater core then back to the T-stat hsg, and has another outlet that goes right into the T-stat hsg.... this I believe is on the driver side inside ege of the head, we see these on both heads, sort of cast pipes with two bolts I believe holding it onto the head

the oil cooler side of the equation, the coolant is flowing through the block there, and it either exits into the oil cooler then onto the T-stat hsg, or moves into the heads.... I don't think that would be too much of a concern... but then again you never know if it would make a hot spot there........

I would just run two hoses, one for the heater, and one for the oil cooler, back into the T-Stat hsg..... you can still bypass everything that way, but the coolant has the chance to circulate like it was designed too....

I wouldn't bother with the bypass hoses, just cork up everything up that's not being used. Put caps on the heater core and upper oil cooler loop *******, and put a pipe plug in the block by the ex-oil cooler. Fewer things to fail and leak. Plenty of SHO engines have been prepared for racing this way, including mine.

Unlike many older engines, the SHO motor doesn't rely on flow through the heater core and/or oil cooler to be the bypass flow when the thermostat is closed. Bypass flow goes through the tube that runs down the valley back to the inlet of the water pump. As the thermostat opens and admits water to the radiator, the disc on the back of the thermostat closes the bypass passage.

On an unrelated note, what size are your remote oil filter lines? Anything less than -10 (5/8" ID) and you might just want to start out by running it with the oil sump dry so you wreck the bearings right out of the box.

Im running AN-10 with only 8" of line total with dual filters. How restrictive is the factory cooler? I would think getting rid of that would be about an even trade off.

-10 is great, it was difficult to see what the fitting size was from the picture, it looked like -8.

The factory cooler isn't all that restrictive, it just isn't a very good cooler for a high output engine that's going to be used hard, like open tracking.

Dual filters is good too, two FL1-A equivalents in parallel will allow all the oil flow the engine needs. The SHO oil pump is a monster, it flows ~12 GPM at 6400 RPM, and that level of flow can overwhelm a single filter pretty quickly, and trying to stuff that amount of flow through small bore lines is asking for trouble. Anything smaller than -10 puts a soda straw in the oiling system.

That's a mighty nice looking build, you have another build thread don't you?

I have two bosch oil filter on the mount right now , I'll throw them out after a few miles of running.

I realy dont have a thread or web page on this thing. Just do a search under my username or go to http://www.fordfestiva.com/forum/index.php and do a search under user name "novass" or subject "minigun". I dont know if you have to be a memebr of not to search forums over there.
