its too cold and my car won't start.. I wanted to install a block heater on it.. can anyone tell me where the freeze plug is at on my '92 nissan sentra

your sentra should have several freeze plugs. Look for half dollar sized plugs on the block.

there is a write up for an SR20, Nissan has one freeze plug with a screw thread for a block heater. It under the intake towards the Oil filter.
People are putting this in all the Nissans from Sentra's to Maxima's.
I will post a link if I can find or copy the material over if the link is blocked

Before you go through all the trouble of putting a block heater in, i'd have your battery checked.
