Replacing A Glow Plug

Need to replace a glow plug on my 07 diesel. Repair instructions say to make sure that the engine is minimum 90 degrees C before removing the glow plug. Any idea how I will know what the engine temp is? Thanks

I would buy an infrared thermometer. 90 C is pretty hot so be careful and wear gloves.

Thanks. I have read somewhere else that if you place a drop of water near the glow plug, it should sizzle and evaporate in 5-10 seconds at operating temp. If it takes longer than it is still to cool.
