starstarstarstarstar 		Engine coolant Temp 205o NEW
by: Terry

After getting my 1993 convertible, LT-1 350 cu inch engine, summer came and with it high temps scaring me to death. It would run at at 205oF and when slowly cruising it would soar to 220 to 230, causing to think something was wrong. I learnrd that when AC was "on" fans run and that turning heater on would cool the engine slightly, or at least hold the temp at 220 or 230. I also note that the hotter the day, operating temps were also higher out of proportion to outside temp. 80 - 85o day, temp would run 205; 90o - 95o, 220o -230o. Anytime you stop at light, temp will soar, even with both fans running. I bought a kit from Ekler than turns on both fans at 200o which helps slow the run up, but it still gets hot. I've been to dealer who told me he'd seen lots of peoole with this complaint, many spending lots of money on one thing or another without much success. He told me this is the way these cars run and that seems right. When weather cools to 50-70o, the car will cruise at 195 -198o and all is well. Even then when you stop at light, up it goes, just not as much, comes down when you get moving. One time I had leaves between radiator and condenser, so check that. The temps of 205 to 240 always scare me, but this has been going on for 23 years. Car has only 78,000 miles since new. Just installed new water pump, thermostat, distributer and plug wires, timing factory specs, both fans work, still dies exactly the same thing. I've decided it must be "normal" but it sure is uncomfortable when the digital temp hits 205+. The regular temoerature gauge always stays below the midpoint mark which is about 180o, rarely it has gone past midpoint to about 200o, but digital read out was 238o. I understand temp probes are in different locations. Possibly manual readout temp probe sending unit could be defective? Just wanted to share my experience.
