Hi All,

When replacing the digital temperature coolant sensor on a 92 (the one in the water pump) do I need to drain the coolant?

I noticed the digital coolant temp does not raise past 142 degrees, also seeing a H15 code.

Thanks for the help you all provide.

Regards,
Roy

You need to drain some you don't want to get your opti wet a good time to flush it take both your knock senors out to do it right.
