Engine Operating Temperature

What is normal engine operating temperature on the Esprit?

What model are you referring to? V8's run a little warmer than 4 cyl and ambient temp affects the temps as well.

As a vague generality, normal operating temp for a 4 cyl would be 85-95 degrees C. V8's approximately 10 degrees hotter.

Are you having a specific problem?

Depends on your location. Here in Georgia mine runs around 90 A/C on and driving. Creeps up to 100 in stop and go traffic I will usually beat the radiator to the punch and turn off the AC and open the windows and drops right back down if I am caught in traffic. Long winded answer, but I believe it should run between 85 and 95.

on the 4pot - if your car is using stock ECU programming (non-chipped):
- thermostat opens at 90°C
- fans come on at 92°C
- tell light comes on at 105°C

if I'm moving and it's 90°F or less - I never get over 85°C. This Texas summer was crazy hot (68 days over 100°F) so my SE spent a lot of time bouncing between 85°C and 95°C constantly up and down.

it's common for the gauge to be a little off so check using Freescan.

The 4 cylinder Esprits have a thermostat that is SUPPOSED to open at 82C. Fan actuation depends on year. (ECU or Otter-switch controlled)

YMMV...I've replaced several t-stats during my 16 years of Esprit ownership.

Again we need to know what year Dere2000 is referring to. If he has a 2000 V8, they DO run warmer...but they are prone to coolant loss out of the overflow bottle in the RR wheel housing. Once the coolant gets low, a proper radiator bleed is often needed.

Same here, my V8 runs up to about 100c when sitting in traffic, the fan seems to hold it there, once you get moving again it's back to 85c.

V8s will run around 85-90 on the gauge when moving, 95-100 with the fans cycling on the craptastic stock radiator.

With a good aluminum unit, you have to try very hard to exceed 85.

My 1991 SE has only rarely reached 90 - it's usually mid-80's.

If it's running hot the first thing to check is how much junk is in the radiator. Difficult because it is "sandwiched" with the A/C condensor coil. It is amazing how much stuff can get caught in there. You also have to be sure the system is properly bled and the header tank is filled cold, and the over flow is filled to the cold mark. The hose between the header tank and the overflow can get plugged up and the low coolant sensor in the header bottle gets dirty and gets stuck in the OK position. Always have 50/50 anti-freeze and soft water in the system. Change it every other year.
