289 running hot
« on: July 25, 2009, 12:10:23 AM »
I have a 1965 mustang with a 289 that has some work done to it. My dad and i put a four core rad in the car along with a electric fan. The fan is rated to move 1500 cfm. It has a 160 t stat along with royal purple coolant aditive. We are still using the oem water pump that came on the car when we got it. I was thinking of putting a fan on that could move 3000 cfm along with a flow kooler water pump and hope that solves the heating up at low speeds. If anyone has any other ideas that would be grate.
Thanks

Two of the best things you can add is a fan shroud and an overflow tank.  Mine was heating up like everybody else's, so I added a 6 blade fan, a shroud, an overflow tank and a 4 row rad.  I also added some "water wetter" and mine runs cool as a cucumber now.  You might also want to rethink that 160 thermo.  I am running a 180 just like the book says.   You need to be careful how much amps you are pulling from your alternator.  If you get that fan, you may be overtaxing your current alt.  Here is the water wetter info.

I had a 4 core in my car for a while but it would not keep up at all even with all that. What I did was got a be cool raditor from summit that is a direct fit since I did this it has never boiled over and this is with the normal fan. This is really expensive but it solves the problem

Yeah, some guys have great results with aluminum rads, but they usually wind up getting a two row.  I know aluminum dissipates heat better than copper, but with a 4 row copper rad, you have twice as much coils for the water to travel through before entering the block again.  I absolutely love my system.  Even on the hottest days here in Texas with the air con on, my gauge never goes past halfway.

If you are relying on a stock gauge, get a infa red heat gun and shoot your engine in a few spots to determine if it really is running hot.

all the ideas discussed have merit. But I'm wondering how much your engine has been bored over stock? If it's 0.030 over or less, then you can fix the overheating. If it's 0.040 or more over-bored, then you might be stuck with the issue.  That said, try the flowkooler water pump first, then go to an electric fan if the flowkooler doesn't made a difference. The aluminum radiator's can make a dramatic difference if none of the  other remedies get you there. A 2 core aluminum will out cool a 4 core copper radiator everytime. These folks have some good prices:

Two of the best things you can add is a fan close and an overflow tank. Mine was heating up like everybody else's, so I added a 6 brand fan, a shroud, an overflow catchbasin and a 4 row rad. Yeah, some guys accept abundant after-effects with aluminum rads, but they usually wind up accepting a two row. I apperceive aluminum dissipates calefaction bigger than copper, but with a 4 row chestnut rad, you accept alert as abundant coils for the baptize to biking through afore entering the block again.
