Engine Radiator Fan Shroud And Overflow Tank

[Spaz]

I just measured the factory shroud opening where the fan would go, it is about 19 5/8 inches in diameter. So as long as your current fan is smaller than that it should fit or be close.

I put on the Mishimoto dual elec fan setup last summer. The previous winter, after putting in the big Mishi alum. radiator, my car would never warm up (I put in a 192 degree t-stat and new water pump at the same time.), so my wife refused to ride in the car with me with no heat. I mean the temp wouldn't rise above the "L" in "NORMAL." So taking a cue from my sportbike, in which the elec fan barely ever comes on, and never comes on while the bike is moving, I figured I'd put an e-fan on my car and get some heat up in here. Since I put it on last summer, I hardly ever have the e-fan on unless I'm in bumper-to-bumper traffic, and as a bonus it feels like an extra 5-10 horsepower.

This is completely off topic but would the heater core be the source of your car not heating up? I think I'm gonna go with an electric fan for the mean time and then worry about a radiator later. I'm trying to buy everything from companies who do their manufacturing here in the U.S so I've gotta do some research and save some money up.

Thanks for your input, looking forward to getting an e fan installed.

The problem with no overflow tank is that ethylene glycol antifreeze is toxic. Cats and dogs alike will lick up the stuff like ice cream and then die. Many years a go I lost one of my favorite cats to what I think was an antifreeze spill. Ever since then I have been very careful to mop up or wash down antifreeze spills.

Some of the newer antifreeze products are environmentally friendly and aren't toxic like the cheap ethylene glycol antifreeze that you may have in your leaky old clunker.

I was helping a family friend last weekend winterize a pressure washer and he mentioned the same thing because he has dogs. Rest assured, I will not be operating my car without an overflow tank and it is not in its running state yet.

I've considered the heater core. But I replaced that and when I let the car idle for a long time without the fan on, the gauge does go up into the middle of the "Normal" and at that point my heater will definitely blow hot air.

Got it. I just wasnt following that is all.

Since I put it on last summer, I hardly ever have the e-fan on unless I'm in bumper-to-bumper traffic, and as a bonus it feels like an extra 5-10 horsepower. The engine revs real quick now, you'd be surprised how heavy the stock fan/clutch setup is. To answer your original question, if you are going to have an engine-operated fan, you should have a shroud. Especially if you are frequently under the hood of your car. Can you say, "Chopped off fingers"? The factory shroud/coolant tank setup should work in your car, kind of depends on the radiator because the factory shroud bolts to the actual radiator, and the coolant tank screws to the shroud. You would be more environmentally-friendly with a coolant overflow tank, as the car would be fine without it (cars didn't have them for 60 years until the early 1970's), because when your car warms up now, it just spills coolant on the ground. The overflow tank allows the coolant to expand into the tank when it's hot, and then pull coolant back into the radiator when it cools down.

Regardless of your fan type, your thermostat was stuck open.
Not only is spilling coolant dangerous to animals and bad for the environment, in this case it would mean the radiator isn't full and the cooling system wouldn't work as well as a result. At a minimum it means more maintenance on the cooling system.

Thermostat definitely stuck open.

I never thought of that, I'll have to swap it out when I get a chance. I forgot to put it in boiling water to test it before I put it in.
