Got home limping.

[TURBOPOWERED68]

I was stopped at a light when the temp. gauge just jumped to 200 degrees so right there in the left lane in the middle of traffic I turned the car off and sat for about 10- 15 minutes.
After the temp got back down to about 195, I then turned the car on and moved to the side of the road. I check the radiator and it’s empty so I go in the trunk and I don’t have any water. I had to walk two blocks to a store and buy a gallon. I poured the water into the radiator and it just empties right out.
So now I sit there for about an hour in 100 degree weather waiting for the engine to cool down. Finally the temp gets down to about 180 and now I am trying to get home in heavy traffic with very little water in the engine and in 100 degree weather.
I wait for traffic to start moving I jump in and go. So now I am picking up speed and turning off the car and coasting to the red lights. Lucky for me I got home and the temps never got above 200 again.
And this is what I found when I pulled the radiator and fan.

i orderd a new radiator for a 1969 chevelle with a 396 and AC
the core size is "i think" 28.5 X 18.5 X 2 inches.

now i need a new electric fan.
what do you guys recomend?

Spal dual 12" fan. Simply an awesome unit.

do you have a part #

this is the one that just died on me. it worked real good but it just didn't cover the whole radiator. i looked under sized big time.

If you're on a budget, grab a ford taraus fan from a junk yard. I run one in my Suburban and even the low setting work really well. The amperage is 15 on low and 30 on the high setting. I read where low is like 2200cfm and high can be between 3600 and 4000 cfm. The high rating seems high but, that's what I read.

 

[TURBOPOWERED68]

thanks
on my way to the Junk Yard in a few
i was over on the Chevelle site and this is what i found
Windstar electric fan pictures? - Chevelle Tech

i want to stay with a dual unit because electric fans can go anytime and NOT likely both at the same time. so you can get home limping and not towed.

I don't know the cfm ratings but the dual fans from an ls1 f-body move a ton of air. The dual fans from the lt1's have the same blades but slightly smaller motors. The Ramchargers dual fans were from an early 90's Chrysler Concorde, I think - you can find it in the archives here several times.

thanks.

Make sure you grab the fan out of a 3.8 liter V6 and not the 3.0 V6...there is a difference.

Try to locate a dual fan from a Mark VIII. They only made them for a few years so I bet they are all the same. Supposed to be the holy grail of OEM fans.

 

[TURBOPOWERED68]

Thanks guys
I found a Windstar dual set up at a local JY
Going to put it in later on tonight
I will let you guys know how it goes.

If that doesn't work out, I have the Flexalite 220 posted above, and I really like it. I fits perfectly and is very low profile.

It became an interesting day.

The parts guy ordered a radiator for a 1969 Camaro which is too small.
And at 6:30 pm I couldn't locate one in any auto store in my general area.
So time to go to plan C
I start to remove the OE radiator from the Regal But half way through my Brother tells me that I can use his radiator from his 68 Chevelle (I didn't even know he had a radiator for his car).
Anyway the "NEW" radiator is in and working.
Now to the fun part.
I cut and cut and cut some more and got the Windstar fans installed and working they seem to pull a little more juice then the Flex-a-lite that I just pulled out but on just one fan (the smaller one) I maintained 160 to 164 on a mixed 18 mile run with very little traffic. But a good amount of lights.

 

[klrv6]

Did you run the high or low speed? Mine is 15A low and 30A high.

I just put straight power to them from my relays.

How do you change the high and low settings?

 

[klrv6]

Nice drawing...Looks like the awesome Mr Coil Pack diagram someone put up a few years ago

You can google taraus fan diagram and see how most people have it wired. I have two 40A relays in parallel for the high side because of startup amperage spikes. The low side just gets one 40A. How were you controlling the on and off before? You may be able to get away with just the low fan, it moves tons of air for 15A. I think most people run the high side when the A/C is on. I never have a problem with it on low.

 

[TURBOPOWERED68]

I put one ON all the time the engine is running (the smaller one)
And I have a switch on the other one

But the fans only have 2 wires each how could I set them to a high and low setting?
Would I need that big ceramic thing that the GN OE fan has?

 

[klrv6]

You could get a cheap temperature switch for switching on the first one. If you have two physical fans, the slow one should be hooked up to the relay that is turned on via the temp switch. The high one could be wired to a relay(s) and switched on only when the A/C is on.

The temp switch could be from any car really, just adapter it to your intake somewhere.

1-They both feel the same as far as speed goes.
2-I may do the second one that way- but first I have to get the AC unit on the car.
3-I can't seem to find a Temp. Switch that comes on at 160 or anything close to it.

Just use the factory fan plug from the Gn harness to trigger the coil on the new relays and take the 12v power feed and ground feed for the relays off the battery, run new power wires to new fans off the new relays and your done. The ECM will still trigger the fan on at the chips setting, and the AC or High speed will still trigger the fan on in a high speed condition.
