Cooling concern

[Bubstang]

My stroker, having been on the road for a couple months, has never ran really cool; like 200deg.F., sometimes 210.
I want to ad AC this winter, but not until I get the cooling under control. The radiator is a 2 row 1" tube Fluidyne aluminum. I also added some 40Below the other night but the effect was minimal. Any ideas without spending $600 for a BeCool?
Oh yeah, I have a highway patrol fan/clutch/shroud/water pump.

Thanks,
Bubba

Bubba,

You might try adding the small circular sheetmetal plate that pop rivets to the back side of the impeller. I have not run one, but if you subscribe to the hype they improve flow about 15%...

I think Be Cool or FlowCooler makes them...my bad: FlowKooler, and 60%!

(ok, that doesn't work! But copy and paste BRA-3875-03 into the part number search...)

Might be worth a try...

Nay!

[Bubstang]

Thats pretty interesting. I will give it a shot.
I have been told that my problem is most likely that the coolant is getting through the system too quickly and not cooling (radiator too small?). Will certainly try this first. Will also let you know what I find. Maybe we should document this for an official tech note.
Thanks again!
Later,
Bubba

Are you siging up for a Tech Day? LOL!

Also, the higher end pumps tend to equalize flow from bank to bank. I'm not sure what % increase in effeciency you get, but...

You might try posting on the Windsor board of the Corral; you might get a good answer from the higher horsepower guys (I'm a 10%er, LOL!)...

Have you noticed the temp being higher at different speeds? Say, between idle and ~35 it's cooler than cruising at 60?

If so, then your air dam is missing, or defective/loose/broken. I can personally attest to the fact that missing one of these will affect cruising temps. Keep in mind, my car does have an electric fan and this might not be the same for your car.

Speaking of electric fans, how about installing one on your car? Would free up some ponies.

[Bubstang]

it runs cooler at higher rpm's, not neccessarily higher speeds. I have a 3K stall and as long as I stay close to stall it drops a few degrees but if I run around 1500 on the street it starts warming again. What air damn are you speaking of, not sure I know what you mean.

Thanks

Thought I'd add my 2 cents.....


A friend of mine switched to the Meziere electric pump and it fixed all his problems. His car usually ran around 210-220 and know stays at a constant 180. This is on a 9 sec mustang that he takes on cruises and stuff like that..This also gives you the ability to cool the car better at the track since you can set it up to run without the car being on. The only problem that I have seen is that you are supposed to run these pumps without the thermostat. This is due to the fact that they flow so well that if you don't, you end up with back pressure and slowly burn the pump up.

Next, like it was said earlier, consider going to an electric fan setup. The following is a fan setup I had recommended to me and was told the application fits perfect. I have yet to get it, but plan to soon. This is also one of the cheapest solutions I've seen to date.

There's a small plastic piece, usually black, that's attached to the bottom of the front bumper (aka bumber).

On my car you can barely see it sticking down under the bumper.

[Bubstang]

I'm pretty sure I don't have one. Anybody got one for sale?
Let me check first...

Thanks!!!

Well Bubba, you may have just lead us to part of the problem: tranny temp due to converter slippage. Do you have an external tranny cooler on it? If not, you might consider the highest GVW you can get. With all the torque you make, you're shearing a LOT of fluid (w/o feelling it), and creating a great deal of heat. That heat is being rejected into the coolant, until the system is eqaulized at the temps you are seeing...

Tranny fluid temp is much more critical for tranny longevity than engine temp; in fact, engine where less the hotter they are (provided you don't detonate them...).

Where is the fan in realtion to the shroud? Suckers should be from half to tw-thirds into the fan shroud for optimum cooling...

The puzzle pieces are starting to fall into position now, and the picture is getting clearer...

Nay,
I have the largest tranny cooler provided by Tommie Vaughn. The guy that built my tranny laughed at me cause he told me to get a big one and the one I got is apparently from a F350 or something, its huge.

From the front of the car towards the engine, parts are in this order. Tranny cooler, AC condenser (not hooked up yet), radiator, fan. The fan is 1" from the back of the shroud and 1" from the radiator. The tranny cooler is about 3"-4" in front of the condenser/radiator. I was told by a guy the other day that contrary to logic, the tranny cooler should be right against the radiator.

Thanks,
Bubba

mmm, blew my theory to heck, LOL!

The cooler located adjacent to the rad would allow more air to be drawn through it at near idle; might be worth a shot...

Do you have a tranny temp gauge on it? Might be worth a few $$$ to install one...

/me crawls back under my rock...

[Bubstang]

no tranny guage. on my list of things to blow money on....right up there with a roll bar ;)

[Neighbors]

I can help w/both :D

Seriously, I have an electric gauge we could install remotely for testing, if you want...gauge is cheap, it's the install that gets you :)!

[Bubstang]

I've got a dented UltraLight temp gauge that I thought about using on the tranny and replacing the engine temp guage but have no clue what the range of a tranny guage would be. I would guess it is quite a bit higher. What do you have?
I'm starting to think you may just have one of everything and several if it relates to a tranny...:D

After re-reading your post and reading Nay's reply, I think he's right. If the heating happens below your stall point, then Nay's 100% right. The convertor is slipping and building up heat, which is getting transferred into the transmission and then the engine.

You might try separating the tranny cooler from the radiator and putting a smaller elec fan on it just to test. But I guess a better idea would be to first see what the temps of the trans are, as Nay suggested.

Think about this too: Say your trans fluid heats up to 300 degrees (I don't know what they really get to, but just hypothetical). The fluid flows to the cooler, which is in front of the radiator. As you know, air must pass through the cooler, then the radiator. What may be happening here is that the trans cooler (at 300*) is hotter than the radiator (at 250*), so, basically, you are heating up the water in the radiator instead of cooling it! If this is the case simply placing the cooler somewhere else might cure your problem!

[gt350mustang]

my 2 cents. move the trans cooler from in front of the rad and mount a small fan on it. did you say you had underdrive pullies? how about the cobra water pump pulley?

[Bubstang]

Thanks for the input!
I am going to try and find an air dam to route some air upwards and then take some tranny temps. Pulleys are stock, not underdrive.

Looks like I'm gonna make CCB, maybe I'll see some of you there.

Thanks again!
