Radiator Cooling Fan Upgrade Pennock S Fiero Forum When centered, the fan blades are about 1 8 inch from the edge of the shroud. loosen the nuts on the coolant over flow tank because it might need to slide over slightly to clear the fan brace. re mount the assembly to the radiator using the four bolts. [this message has been edited by pauljk (edited 07 21 2007).]. How far off the radiator is the frame of the aftermarket fan? if the new fan is too close to the radiator, you end up blocking the rest of the radiator from having any useful airflow. that wouldn't be good. 11 sept 01, the day the world as we knew it ended.
Radiator Cooling Fan Upgrade Pennock S Fiero Forum I pulled up to the drive thru last week, the cooling fan kicked on, it was embarassing noisy, vibration, etc went to lane automotive and purchased a spal 16 inch puller fan, model # spa30100231 $98.00 if you cut the 4 arms that hold the original fan and motor flush with the rest of the shroud, the spal will set right in the shroud like it was made for it. i used 4 machine screws with lockwas. Originally posted by 1985 fiero gt: the radiator fan only spins when the temperature of the coolant has reached something like 235°, or the ac is turned on. the belts run the water pump, which circulate coolant through the engine at all times when running, and through the radiator when the temp is above 195°. As a comparison, the fiero fan was pulling about 15 amps. the volvo fan pulled 13 amps on low speed, and 21 amps on high. low speed felt about the same as the fiero fan. on my 3800 sc engine, with a 2 core radiator, low speed will pull the temp down about 20 degrees in about 2 minutes. Frequently radiator tanks blew off had nothing do to w anything but old age. fiero oe radiator is 25 years old. (see cave, rad failure in coolant section) many suffers weak no coolant and likely no maintenance either and radiator & heater core is block by dirt rust etc. so comparing tired old to new is wast of time.

The fiero specs are not listed but i highly doubt its cooling fan flows more than the 1990 3.1l camaro 14" cooling fan at 1050 cfm through the radiator. the 16" fan for the camaro moves 1150 cfm through the radiator and so does the cooling fan in this thread from the volvo according to the hayden site.
