can a pick-up truck run without a thermostat?

Answer 1

no- the engine will overheat and will have no way of regulating coolant temperature.

Answer 2

Yes it will, although it will run cooler. They use thermostats to keep an engine at a specific temperature. When the thermostat closes, it retains the coolant in the engine until it increases to the same temperature at the rating of the thermostat, usually 180 or 190 or 195 degrees, at which point the thermostat opens and circulates the coolant throught the radiator where it is cooled. Removing the thermostat used to be a common practice in warmer climates where you want your engine to run cooler more than you might need hotter air blowing through your heater for defrosting, etc. But in today's automobiles, removing the thermostat will screw up your emission control system as it is designed to operate at a given temperature. While it truly won't hurt the engine, it could make it run poorly by forcing the ECM to make adjustments to compensate for the temperature difference.

Answer 3

Emissions of Hydrocarbon and Carbon monoxide will go up because the engine is to cold to long. Modern fuel injection and exhaust emission control require corect fuel mixture control so most engines run on the lean side and almost hot. 240 degrees is not at all uncommon. Remove the thermostat and even light the check engine light. If the truck has a overheating problem that is not fixed by replacing the thermostat look elsewhere like tree seeds cotton wood and other clogging the cooling fins of the radatator. Or coolant flow inside the radatior because the owner decided to allow the cooling system to rust. Water is not a replacement for the proper coolant water mixture.

Answer 4

The thermostat in all cars and trucks is there for a reason.The thermostat keeps the engine at the correct temp for the fuel injection system to work peak.Without the thermostat the onboard computer will run the fuel injectors like the engine is cold.Low timeing curve and max fuel injector spray.

Answer 5

Has an motor vehicle technician ever shown if there are certainly any exhaust gases present day interior the radiator/cooling device? it is extra often than not finished the two with a chemical approach "Block examine" or with an exhaust analyzer which will degree the presence of unburned hydrocarbons interior the coolant. Are you using production facility alternative areas or after marketplace areas? There are no regular overheating problems with the Ranger 3.0L engine, and the radiator is a single row layout without HD version with 2 rows available. Do you run a 50/50 combination of the the main suitable option coolant/water? working a hundred% coolant would reason the engine to overheat. What thermostat are you working, does it have an air bleed passage? we used to drill a small bleed hollow to circumvent trapped air at the back of the stat.

Answer 6

any vehicle can run without a thermostat however it is not recommneded, for one you wont have very much if any heat and for another reason vehicles are designed to run "hot" thus running with out a thermostat could cause severe engine damage after a while. However if your truck overheats a lot this is a cheap fix for a while.

Answer 7

an engine thermostat is a vital part of your vehicle. it tells you what is going on inside the motor. since your engine produces heat from combustion and too much heat is a very bad thing, then you definitely need a thermostat if your going to drive it anywhere other than to go a mile or so to get it fixed. remember that a thermostat only works when there is water in the cooling system. if you have no water everything will seem fine but you are in for a very expensive mistake. a good friend of mine found this out in his cummins diesel and since it is not a good idea to try and rebuild a overheated cummins, he spent over 6,000 for a new motor and that was a bargain. it is good to always check your water level before you travel somewhere if you are using an older vehicle or one that has a leak somewhere.

Answer 8

Obviously some people dont know what a thermostat does, it dosent keep the engine from over heating, unless it is broken, but it is temperature actuated to open when the engine reaches a certain temperature, without it, the car wont reach full operating temperature and you will not have heat, but will still run without a problem.

Answer 9

Yes it can. It will be like the thermostat is stuck open so it might take some time to warmup.

In the warmer weather it's not so bad as it will get to operating temp.

In cooler weather the engine will run cold a lot longer and suck extra fuel. Also in cooler weather the engine will cool down while running as no thermostat to slow flow of coolant so it stays hot.

For newer vehicles it is not recommended.

Answer 10

Yes, although in the winter time it will take quite a while before the heater starts working due to the coolant continuously running through the engine. So the engine has to heat up all of the coolant before the heater will start to work. In the warmer month it can cause overheating due to again the coolant continuously circulating and not having enough time in the radiator to be cooled down properly.

Answer 11

yes but it will run cold for a while cuz the thermostat keeps the fluid in the motor until its warm then the thermastat opens up and slowly lets the cold fluid in until the the thermostat is wide open which is usually operating temp
