Lower temperature fan switches for Fiero's
The stock thermostat on the 85-88 V-6 Fiero and 84-86 L4 Fiero is 195°. The stock fan switch does not turn on until the coolant temp hits 235°!
There is a better way:
My 195° on and 185° off or my 210° on and 200° off fan switch will keep your Fiero running cool.
The 200°-210° fan switch allows you to retain the stock factory 195° thermostat but will turn the fan on at a more reasonable temperature! Just sit back and drive with no overheating worries!
Worried about "closed loop" operation? Closed loop occurs between 125° and 150° in the Fiero. Fuel mapping does get slightly richer at a lower temperatures but only slightly in this range. This comes from several "experts" in the field of engine management.
Fan switch location on the V-6 intake manifold.
To replace the switch you only have to remove the black rubber hose above it. If you replace the switch with the engine cold you will not loose a drop of anifreeze!
Installing this switch requires no wire cutting. The connector is the correct one for the stock Fiero wiring harness.
No need to sit in a traffic jam and worry about the coolant temperature and when will that fan come on!

Stant 13818 180 degree thermostat must be used in conjunction with the 195° /185° fan switch. A 210° on / 200° off switch is also available that will work with the both the stock 195° thermostat and the 180° thermostat and provides an excellent increase in cooling efficiency.
Note: Will not fit 84-86 L4 engines equiped with air conditioning, as these models use a dual connector switch. You can convert your dual speed fan to run on high only. There is no need to have a dual speed fan on a Fiero. Click here for this conversion kit.
Does not fit the 87-88 L4 Fiero. The fan is controlled by the ECM on the 87-88 L4 Fiero.
This switch fits most GM engines. It will also fit many other non GM engines as the 3/8" x 18 NPT is a very common size for fan switches. It is popular with Lotus owners.
The thread size is 3/8" x 18 NPT. If you would like to use this in a different vehicle the correct pigtail is available here.

Shipping: Shipping in the USA via First Class Mail is a flat rate of $5.00
Shipping to areas outside of the USA: Generally I ship postal air first class mail. Shipping varies depending on what country they are going to. It ranges from $6 to Canada to $11 or more to Australia etc.
I do not offer free shipping.
Because I use postal flat rate boxes for heavy orders there is no program that can add the proper amount of shipping to every order. So all shipping is added manually by myself after you place your order. That is explained here: Shipping added later explanation
When you place an order the shipping amount will show $0.00. Soon after you place an order you will receive an email confirmation that shows the amount of shipping that was added to your order.
