low Coolant Sensor offering false readings since of entry gasket leak. I've had actually the gasket replaced however the Sensor is still acting up, showing Low Coolant once the coolant is no low. Moreover the short Coolant light generally goes off as soon as the engine has warmed up after three or four miles of driving. My inquiry is room the low Coolant Sensor and also the Engine Temperature gauge connected? have the right to I overlook the low coolant light and also use the engine temperature gauge to identify when mine engine is truly short on coolant and overheating.Tks

Hi. Came across your message around the low coolant sensor. I have a 2001 Buick Century v the very same problem. Low Coolant light come on even when coolant is not low.If you"ve uncovered the prize I"d appreciate knowing what the is.Thanks.Johnjohnandjanet
shot removing the lowcoolant sensor native the reservoir bottle and also cleaning it.If that doesn"t work, replace the sensor.
I had actually the same difficulty shortly after ~ correcting a reduced intake manifold leak that had enabled oil to enter the coolant. The oil apparently fouled the sensor. I can"t mental if i tried come clean the or not, however I do know that ns ulitmately changed it and also the difficulty went away because that good. The sensor is on the passnger side of the radiator below the radiator cap. That is black and square and has a single plug at the bottom. That is organized onto the radiator by a metal retaining clip. Remove the clip and the sensor pulls the end of the radiator. Disconnect the cable by pulling very closely on the plastic lock and also pull ~ above the plug. Fluid will leak out to level that sensor. Drain or ar catch basin below sensor plug to capture radiator fluid. Ns ordered mine replacement component from E-bay.

mine Buick had actually the low coolant light on intermitently. After 3 times in the shop (the catalytic convertor likewise went out) the is quiet on. Problem is the mechanic changed the head gasket ~ above that 3rd trip, an high-quality repair together oil was leaking into the coolant from the engine. That actually gave it ago to me through the light still on. I gather that did not change the sensor which to be gummed up, so ns took that elsewhere and they switched the end the sensor. Now after a month the sensor is back on solid.So my inquiry is, because the sensor to be replaced, can there have actually been residual oil still in the coolant which is now gumming increase the new sensor? Is that even possible to change the head gasket without draining turn off the old coolant? i hope it would certainly be very unlikely the they could have screwed increase the repair in together a means as the is still leaking.I can't bought any an ext repairs. I would certainly appreciate her input.Thanks
