The fan is in front of the radiator, and is blowing air across the radiator fins. It is not between the radiator and the motor. I will borrow an infrared thermometer from work and check the housing temperature. Didn't even think of that one and I work in a chemical plant! Thanks.

Well thank you everyone! To comment on some of the feedback... Mechanical gauges.... I agree. I know that any gauge can be "manipulated" to read whatever you want. I just want an accurate one. My plan is to add something so that I am not relying on a 50 year old temp gauge. Previous owners are the dumbest shits..... I agree! One of the previous owners installed a "kill switch". It basically was some speaker wire run from a toggle switch under the dash to interrupt one of the terminals on the coil. What the hell? I removed that right away. It should have a thermostat switch that turns the fan on only when needed... That is what I plan to do with the extra fitting on the Koyo radiator. This would be if I didn't go back with a mechanical clutch. Fan location behind rad is OK as long as fan is not blowing air forwards... It isn't. It is blowing across the radiator. Running hot... Not sure if it is. This is why I asked what people are typically seeing on their gauge readout. Granted, the gauge is mine was only on the 68 and 69, I figured I would ask. Be sure the rad is not blocked by leaves and debris on the front that restricts air flow... Done Are the fins clear? Yes Fog lamps? Grill Yes and Yes Are the heater hoses connected together because the heater core leaks? No Rev engine high and watch the bottom rad hose. It is new. Check engine timing. On my list of to do items. I need to research and see what timing needs to be set at as well. Block any openings in the rad support or around the rad that are not used. Already done. Always run50/50 anti-freeze water mixture.... I agree Add a coolant recovery rad cap and collect all overflow so it can be returned to the rad when it cools... It has an overflow bottle, but I don't know if it has a tube going to the bottom of the bottle. I will check into that! Paint the rad flat (not shiny) black. Flat black radiates more heat..... Will keep that in mind for the Koyo. Again, thanks guys.

Thanks for the welcome! As for the pictures, what do you want to see? Here is what I am thinking... Picture of the temp gauge Picture of the current setup Let me know if this is what you mean. Also, and since I am new, is the only way to post a picture by a url? We can't attach a jpeg, bmp? Thanks!

Bought a 69 about a month ago, and love this thing. Needs work, but very complete, and very little rust. Well, on to my question... So as you see, I live just 2 miles north of the core of the earth, here in Houston, and it is already blazing hot outside. The dime has what looks to be a standard radiator, and an L20B motor. One of the previous owners thought it would be good to remove the clutch fan, and install an electric fan between the grill and radiator. The temp gauge in the car has a small dot, just past C, and about two thirds of the way to H. What is this mark for? I am assuming normal operating temperature, but I could be wrong. I haven't driven it too much in the heat, but cruising down the freeway, the temp gauge goes above the small dot mark. My plan is replace the radiator with a Koyorad Aluminum radiator. My next question.... Should I replace the electric fan (which is hard wired to stay on) to a clutch fan, or get a new electric one. Also, should it be mounted between the motor and radiator, or is the current location acceptable. I feel that since it blocks the natural flow of air across the cooling fins, it would be best served to put it between the radiator and motor. Be gentle.... First post on the forum!
