Q: I bought a 1988 Camaro IROC-Z with a 350 TPI (the second I have owned). My question is about engine running temperature. When the car is not moving faster than 30 miles-per-hour, the temperature climbs over 200 degrees, and the fans won’t turn on until the temperature reaches 240 degrees. Both of my IROCs did this.
A: There are a couple of more cost-effective ways to get that engine temperature down. One is with a fan switch that kicks the fans on at a lower temperature. JET Performance makes a switch that engages the fan at 195 degrees and turns it off at 185 degrees. You can also get a thermostat that opens at a lower temperature such as Hypertech’s 160-degree or 170-degree thermostat.
We would try these parts and see how much the temperature changes before thinking about a new radiator or high-flow water pump.
