First welcome to the site.

Second, I'd check the cfm of your fan. It might not be moving enough air.

Is it a pusher or puller fan?

What about a shroud, are you using one of them?

 

do you have a shroud? I made sure I got one, you lose alot of airflow without one. I hope you get it figured out, would like to run into you at cruisin the coast.

 

Fwiw, I have known a couple of guys who had a flat type of "shroud", and it actually made the car run hotter. Removing it took care of the overheating problem. If the shroud isn't funnel shaped, it can block the air flow in the area where it's covering the radiator. Might as well just cover that area of the radiator with duct tape...almost. I don't have a shroud on mine, and the 14" single fan keeps the engine cool as a coocumber.

 

that makes good sense 69er. it explains why Ive seen so many with electric fans not running shrouds. I happen to have one of those flat aluminum shrouds. I will be monitoring my Temps closely this summer and will probably end up running it without it just to see what kinda diff it makes.

 

I actually made one of those flat style shrouds for my car, have an aluminum radiator and a 16" puller fan. A friend of mine that lives in So Cal has a Camaro and he did some testing with this sytle shroud and different depths and he found that a 3/4" depth worked the best.

I think the main thing is, if you don't have a large enough CFM fan to pull/ push the air through the radiator/ shroud, that's a problem.

Of course there are other issues that could cause this problem, like timing, water flow, radiator size, etc.... but I think this area, fan cfm is over looked a lot.

 

just measured mine.... thats exactly what I have... 3/4" inside air space.

 

And your car sometimes runs hot dun it? Hmmmmmmmm!!

 

not mine. if anything its been running too cool. i keep turning the thermostat up on the fan so it doesnt run so much. I think you misunderstood my issue. the only gauge I have is the saw tooth gauge which just shows hot and cold, not the actual temp. so I got one of these...



and it never shows over 180. but like you said before.... thats the water in the Radiator right?

 

Right, I remember in your other tread where it was registering hot, but didn't see or hear what the outcome was temp wise.

 

yea it was that AutoMeter gauge I saved from the fire.... just wasnt reading correctly with the temp sensor I have. sorry I didnt relay that info back did I. my bad. I still intend to put a "Mechanical" Temp gauge in per someones suggestion. Ill get to it soon.
