When i first bought my car it would take like 20 minutes for it to get warmed up. I figured it didnt have a thermostat since it always ran so cold. Then recently as ive been driving my car daily, it now takes the regular amount of 5-10 mins to get to 1/4 temp. When sitting it gets to 1/2 but the fan almost never turns on. While driving it stays around 1/4 to near 1/2 temp, and it varies. Now, is there a SIMPLE way to check if i do have a thermostat and my 2nd question is, is it better to run with NO thermostat, or With?? i have a 94 integra with 190k
