I finally got tired of the noise and inefficiency of the mechanical fan on my 88 5.7L. The temp would rise sitting in Atlanta traffic. The clutch likely needed to be replaced but decided to switch to electric fans.
This is my daily driver and it needs to be reliable. There are a number of different ways to do this swap. I followed the method from TBICHIPS.COM.
http://tbichips.com/?page_id=46
Required parts:
- LS1 Fan set (I used a Dorman part) $130
- Temp switch (used a universal switch @ 175-195) $10
- Four blade relays (2) $3 / each
- JB Weld (to support the temp switch in the thermostat housing) $6
- Thermostat Housing $10.
Steps:
- Pulled the mechanical fan and shroud.
- Wired the fans and routed the wires to the firewall.
- Wired the relays and mounted to the firewall.
- Drilled the hole in the t-stat housing, placed a bead of JB Weld inside and outside of the switch.
- Mounted the t-stat housing.
- Let it sit overnight, fired it up the next day. Runs great.
It went pretty well. The fans could use a nicer looking top bracket to replace the tie wraps. I may fab a couple of brackets for the fan and radiator. For now, tie wraps work. Keeping an eye on the current draw. Might eventually need to upgrade to a 140amp alternator.
So far so good.
