What finally worked well was using the tip of a small flat bladed screw driver to press in on the slot of the electrical connector latch, while holding it up against the engine, and gently pulling on the sensor to separate.

I also didn't have success following any of the recommendations on how to unlatch and separate the electrical connector provided. Lube the O-ring to reduce chance of pinching.Ģ.

This provides ample stress free time to separate the electrical connector and connect the new sensor.
Simply pull the ECT out with one hand, verifying the O-Ring comes out with it, then pop a wine bottle cork into the hole with the other hand, stemming the flow of coolant. Especially since coolant still drained out when pulling the ECT. While I jacked the right side of the car up, pulled the panzer plate, and drained the coolant, I wouldn't again. A wine bottle cork fits in the ECT hole perfectly. Wanted to reciprocate by sharing what I experienced and learned.ġ. I really appreciate all who posted, your posts really made replacing the ECT straight forward on my 03 Jetta Wagon. Isn't it funny how a $40 piece can cause so much troubles! was on its way out and we thought we would need replacing, Pretty scary since they're over $4000 to replace. gauge in the car always indicated normal even when the scan gauge showed -45 would start acting up, hard shifting, slipping ect.I guess the ECU was telling the trans that temp and adjusted shifts accordingly. I was driving the car and noticed it would show normal operating temperature, then suddenly it would show a coolant temp. By chance I hooked up my scan gauge but no codes were ever thrown. She complained about the car bucking and slipping between gears. This sensor was a culprit of many odd transmission shifting issues. with no option left, I removed the upper coolant hose connected to the flange where the sensor was, stuck a long drift pin an gently knocked the sucker out. Eventually the plastic plug was all broken and cracked. That bugger refused to come out after twisting and prying. Similarly, when the engine coolant temperature decreases, the sensor resistance also decreases, which sends low earth signal to the temperature gauge, and the indicator rests on the cool indication.I replaced the coolant sensor in my GF's 2006 golf 5sp Auto. When the temperature of the coolant increases, the resistance of the sensor decreases, which sends high earth signal to the temperature gauge, and you see the temperature gauge indicator fully turned to the hot indication. Higher the temperature of the engine’s coolant, the lower the resistance of the ECT sensor, and vice versa. The coolant temperature sensor provides an earth signal according to the temperature of the coolant. In three wire coolant temperature sensors, the ECU does not control the temperature gauge in the cluster.
The two wires, a “5-volt reference”, and a “ground wire” go to the ECU, and the third wire “Earth Signal Wire for Temperature Gauge” goes to the cluster-mounted temperature gauge by providing an earth signal to the temperature gauge.
