This Civic Si is also lighter and stiffer than its predecessor, though Honda doesn't specify exactly by how much. Adaptive dampers with Normal and Sport settings are standard, as is a helical front limited-slip differential. The Si also shares its front upper control arms with the ultra-hardcore Civic Type R.
The seats in both vehicles were cloth. RESULTS Within 20 minutes, readings in both cars exceeded 125 F and reached a maximum stabilized temperature in 40 minutes (Figure). The temperature rise in the first 10-minute interval was more severe for the dark-colored enclosed sedan than for the light-colored minivan. The maximum stabilized temperature was also higher for the dark enclosed sedan (140 F compared to 138 F), which was a temperature rise of over 45 F in less than 1 hour.
When ambient temperature is 75d and coolant is 190d, temperature differential driving heat out of the radiator into the air is 115d. For this you can use a radiator 40% smaller than for conditions described in the prior paragraph.MGs are sports cars built to be as light as possible (within economic reason).o the answer to the question is, normal operating temperature is a range with minimum determined by the thermostat. Maximum it determined by work load of engine, size of radiator, and ambient temperature (and requiring some minimal air flow to keep it working).
