Question about 1999 Isuzu Rodeo
The water temp (coolant temp) is cold all the time? Thermostat stuck open. Replace, not good for car. Computer can't adjust well to that and will cause fuel economy issues, never allow car to warm up properly. Opposite of thermostat stuck shut causing overheating. If the water can't be restricted enought to heat up and then be maintained at the correct temperature your car is not operating efficiently, won't pass smog I'd assume, etc. Thermostat is at end of upper radiator hose in thermostat housing. Two bolts to remove. Pop out thermostat and see if its stuck open. It'll have a gap if it is and it will be shut if not. You can boil water vigorously and hang your thermostat in it with a wire or something and watch it. It should move open from closed at a noticeable rate. When removed after fully opening, it will close as it cools. If it doesn't move and is stuck or moves EXTREMELY slowly it's done. Replace gasket, replace thermostat, light coat of sealant on gasket if you wish and torque down evenly. Replace lost coolant. Hope this helps.
