Many things can cause an engine to run hot, make sure that the cooling system is full, that there are no leaks, make sure the cooling fan is operating properly, make sure that the there is nothing blocking air circulation thru the radiator fins, check for corrosion inside the radiator causing blockage and reduced cooling.
A thermostat that is stuck in the closed position is a very common cause of overheating. A new thermostat should be installed every time the coolant is changed.
Replace it with the exact same temperature thermostat as the one you removed. Do not run the engine without a thermostat. The thermostat is required to keep the engine running at the optimum temperature that will give the best performance and mileage. If it is overheating running it without a thermostat is not the solution.
Yes, an engine can overheat without a thermostat. The thermostat regulates the flow of coolant to maintain optimal operating temperature; without it, the coolant may not circulate properly, leading to inefficient cooling. Additionally, the engine may not reach its ideal temperature quickly, which can also cause overheating under certain conditions. Overall, the absence of a thermostat disrupts the cooling system's balance, increasing the risk of overheating.
Take your thermostat out and put everything back together, run your car without a thermostat... If your car no longer overheats, replace your thermostat.
Lack of coolant, cooling fan not working, thermostat bad, bad temp. sensor, fuse, relay for the fan, water pump, head gasket, cracked head or block. Without more information, it is impossible to point to anything in particular.
1) ONE THING YOU COULD TRY IS CHANGING THE RADIATOR CAP...IF IT'S BAD THE CAR WILL BOIL OVER AND APPEAR TO BE ALWAYS OVERHEATED WHEN ALL THAT'S REALLY WRONG IS THE LACK OF PROPER BACK PRESSURE DUE TO AN OLD/DEFECTIVE RADIATOR CAP. 2) IF THAT DOESN'T WORK YOU COULD TAKE THE THERMOSTAT OUT AND TRY DRIVING THE CAR WITHOUT IT IN AND SEE IF THE CAR RUNS LONGER BEFORE OVERHEATING...IF IT DOES THEN THE THERMOSTAT IS STICKING. THE THERMOSTAT COULD ALSO BE UPSIDE DOWN...IF IT IS IT WON'T WORK RIGHT. patricklaw1957@yahoo.com You might also check the timing.If it is retarded due to a bad timing chain or needing a tune up this will cause overheating.
Bypassing a thermostat involves connecting the heating or cooling system directly to the power source without going through the thermostat. This can be done by connecting the wires that would normally go to the thermostat directly to each other, effectively bypassing the thermostat's control. However, bypassing a thermostat is not recommended as it can cause the system to run continuously and may lead to overheating or other issues.
It won't 'blow' your engine to run it without a thermostat. However, it could accelerate wear on the engine over the long term. Also, fuel economy and heater performance will generally deteriorate. Simply put, engines are designed to be run at a certain temperature. For this reason, it is always best to run an engine with the proper thermostat. If your engine is overheating, then the cause of the overheating should be found and addressed rather than trying a band-aid fix such as removing the thermostat.
prob a 16 but that would be pushing it 22s will fit without changing anything
Your 1993 Grand Marquis may be overheating without the thermostat indicating a problem due to a faulty thermostat, a malfunctioning coolant temperature sensor, or low coolant levels. Additionally, a clogged radiator or a failing water pump could impede proper coolant circulation, causing overheating. It's essential to check for leaks, ensure the cooling system is filled with the correct coolant, and inspect for any obstructed hoses or components. If the issue persists, consider having a mechanic perform a thorough diagnostic.
Technically, yes they can run without a thermostat. (not without coolant, just no thermostat) However, several things will happen. First, the engine will be cold all the time which will make it use more gas. Also, your heater will not work. Another thing is that your engine will not produce as much power because it's cold. etc. note: if this is being done to fix a problem like overheating, it will only work if the problem is caused by a faulty thermostat.
An independent variable is something you can change without changing anything else.
