Thanks for the link I read that a long time ago and it seems like he recommends the dewitts with the electric fans (although he prefers the clutch setup)

Thats pretty much what I have Alumitech(think Don that had alumitech was a former employee of dewitts and used cores from Dewitt?) instead of dewitts and dual 11” spals.
Chinese hv waterpump
Trd alu v belt pulleys 1.1:1 ratio
Powermaster 140 amp and upgraded wiring
Milodon 160 deg highflow thermostate
Warmest outside temp I have seen is 95 deg f.

Engine runs 157 deg intake/178 deg head with at idle/cruise/stop and go traffic
Slower speed 165/185
Highway speed 170/190

I've thrown the photos up on a google drive here so you can view the full size image: https://drive.google.com/drive/folde...Tk?usp=sharing
Although I say the radiator has low mileage on it I don't know the history (that just went back to when I bought the car) and it's ugly inside so I think it's time to just bite the bullet and invest in a new setup that will work and not cause me issues anymore.
Checked out the Pics on your site you put in your Post

I believe it is the Belt from the Water Pump to the Alt that is crooked/out of not being Straight

Also that big A/C Cooler/Condenser in Front of the Rad does not help
it slows down the Air Flow plus the Heat from it heats up the Cool Air before it even gets to the Rad Core

In addition unless you have very good Efans( SPAL ) they will not be able to
Pull Air thru a 3 Tubed Rad Core and a A/C Condenser as sufficiently as a Mech Fan set up can

Where ever you buy your new Rad from have them install the Brackets for attaching a Efan/Shroud setup
https://www.dewitts.com/collections/...adiator-manual
DeWitts 1149003M which has the 2 Row 1.25" Tubes


Dewitts attaches a Bracket for the 11" Efan/Shroud but I would think you could use it for the 12" Efan/Shroud


And buy the SPAL Dual 12" Efan/ Shroud Unit
https://webstore.spalusa.com/en-us/p...pksl-dual.aspx



I just have the SPAL Dual 11" Efans/Shroud Unit on my small DF Rad
and it does the job at keeping my Engine running at the Temps I like
170* + - on the Hwy with NO Efans because the Flaps are open
or in the city/back to back runs down the Track with one on at Launch and then turn the 2nd on after

Here is what my Unit looks like
67 Manual DF Rad

SPAL Dual 11" Rfans/Shroud

How they look together if you get or paint the Alum Rad


Here is a pic of it in my 67


You can see the Top of the Trans Cooler in this pic

I believe it's an optical illusion. I've checked it and don't see anything off plus I've had no belt wear or noise.

I was wrong it's a 4 row radiator. One thing is I don't have an overflow bottle how much of a difference would it make if I had one? Is there a chance my timing is off and it's causing it to run hot (due to lean or rich condition)

As you can see I'm very space limited in the engine bay so I'll have to do some measuring to make sure whatever I go with will fit with the current pulley setup. My current fans measure around 3" deep (possibly less).

Re: New radiator help

Dustin
if you go with the 2 Row Tubed Rad it will be not as Thick as your current 4 Row one
and therefore the SPAL Dual 12" Efan/Shroud should fit !!??

If Timing is off it could be running to Hot
but you said it is only running Hot on the Hwy
so I think the Bottom Hose is collapsing plus the old Rad could be clogged up

I've only noticed it on the highway but I don't have a whole lot of miles on the car either

Re: New radiator help

Alright just ran the car in the driveway for probably 20-30 minutes while I adjusted the IAC on my sniper. My Sniper showed 185F and held it my gauges showed 222F and help (sniper sensor on top of the intake gauges on the drivers side of the engine)

I just followed his plan for stock original fan and rad.Works perfect and nothing to screw with.
