![]() ![]() I would start with ordering the correct 1971 part and then compare it to the 1976 part and see if it could even fit, or at least get a ohm meter on the sensor and see what the range is you can use a pot of boiling water to test the sensors. Action: Follow the Service Procedure steps to. To correct the condition, follow the Service Procedure steps to replace the long block engine assembly. This may be due to coolant intrusion into the cylinder. But when the low coolant sensor turns on and off no matter what the season is, you may have several questions in mind. Diagnostic trouble codes (DTCs) may include P0300, P0301-P0304, P0316, P0217, P1285 and/or P1299 stored in powertrain control module (PCM). Coolant or more aptly antifreeze is that colored liquid that prevents water from freezing in winter and from overheating in summer. However, the light may remain on or can come back on due to another issue, such as a coolant fluid leak or a problem with a sensor in the system. In most cases, simply topping off with the correct fluid will resolve this issue. So you would need to see if a 1971 coolant idiot light sensor can fit the same threads in the 1976 block, if it does you could swap the sensor and that should turn the light off.Īs a hack, you could install a 5Watt lets say 10 ohm resistor inline with the current sensor that would increase ohms and might turn the light off but then it would be even less calibrated to when the light should turn on. Low Coolant Light Comes On and Off 4 Common Reasons. This warning light most commonly comes on to let you know that your cars coolant fluid level is low. if you change them to blue, you will have this light illuminated in blue, and it can't really be the warning light You can also check the fuel gauge on the other side, you should have the pump icon lighted but this not means that you are running out of gas. Since the temp here in nj has gone up quite a bit Ive noticed my check coolant light has been coming on once in awhile when the car heats all the way up. ![]() Later model engines like 195-200 degrees F for proper electronic engine control function. Oh, and the smell gets worse during hard acceleration because the water pump is spinning up and pumping more coolant through your heater core leak. Then you have a 1971 mustang idiot light coolant sensor which is different from the coolant temp gauge sensor. In the first picture it is red only because you are using red ambient lights. Vintage Mustang engines like to operate around 180-200 degrees F coolant temperature. My low coolant light has started to come on at times, but both the radiator and overflow are full. +1, but it doesnt explain the power loss or the coolant light with coolant not being low. Well if you are sure the engine is not overheating my guess would be the coolant sensor for the 1976 engine has a different ohms reading then the original 1971 mustang coolant sensor.īeing a 1976 that would be a winsor sensor. ![]()
