Seeking Help / Advice Regarding Coolant Temp Sensor

Hello,

I have a 2003 406 Hdi 90 hp. When starting from cold Stop Engine Warning Light comes on & "Engine Temperature too high" message comes up on display.

So ordered a Bosch Coolant Temperature Sensor online. OEM Part Number: 0 986 280 404
Link below:

This is a threaded / screw in type of sensor.

However, the original one in the car is a push in type that has a retaining clip holding the sensor into the housing. Link below to an image of the original type of sensor currently in the car. If you cut & paste into Google it brings up an image.

I have looked online at a few online sellers & they all give the Part Number 0 986 280 404 and images online are threaded / Screw in & not push in Sensors.

Would be very grateful if anyone could throw some light on this for me? Or if anyone knows a part number of the part I need.

Thanks in advance.

Couldn't get either of your links to work, but I reckon you need an OE part no. 1338 C1

Google that and you get many options, including https://www.ebay.co.uk/itm/290676836737 (which has a decent picture)

Should be available form your local motor factors / parts stockist
