Hood question

Typically if its hot on the highway with electric fans, I blame the fans for blocking airflow. If its hot while stationary (where electric fans do their best work) I suspect not enough fan.

Either way in this case, I feel strongly that its the electric fans. When someone says "overheat" and "electric fan" in the same sentence its almost always the culprit. Either they're restricting air flow on the highway, or they're not providing enough flow while stationary.

Of course the single row radiator doesn't help either. Bio.. you could have a three-core copper brass radiator built from scratch for about $400. They would use GM tanks and a good Modine high-efficiency core and it would cool MUCH more efficiently than your single core aluminum.

Although I like the suggestion, money and space is a huge issue, mainly space. The old 2 core had about 1/4 of an inch between the electric and belt driven fans. Although the old and new radiators are on-par with width and height

The main problem is that we do not know that to do with an absolute max of:
Width 25 1/2
Height 17
and Thickness of 3 inches
I'll see if I can get pictures of my current setup

Just curious, are you sure the gauge works right? Also when you installed that engine, are you sure that the hose routing is right?

The gauge is correct, and the hoses are routed correctly. Or at least how the car allows

Ok, heres were I start shouting:

DETAILS DETAILS DETAILS!!!!!!!!


A photo would help, but from what your saying it sounds like your still useing the belt driven fan with the electric fans?

And we still don't know when it over heats?

As TSC suggested it could also be a problem with the hoses, you never confirmed they were free of kinks, or sharp angles, things that like to restrict water flow.

And just how many radiators do you have in there?

I lightend the picture that you linked so that we can accually see the radiator. You have room to fit a massive radiator in there, your fan is a good 3-4" away from the radiator.



From just looking at the picture, air one could be reason also, the highest point in the system is the bend in that top hose.

Agreed with the 3-4"... You could put a four-row, 4" radiator in there and still have over an inch back to a mechanical fan. A shroud, a replacement lightweight fan from Summit, and a good stock thermal clutch and your problems will go away, I guarantee it.

You just can't ask an electric fan to do the job of a mechanical. I think your problem is your insistence on using parts that don't work. I know electric fans save a couple hp, but there are no free rides. Remember, a 20amp draw can mean as much as a few hp draw at the alternator.
