Ok so im new to the Nissan game! Bought a 1990 Nissan 240sx SE the other night for next to nothing! This is the first Nissan I have ever owned. And I love it! The car has very little heat even with the heater on full blast. Anyone might know what is causing this? All help is greatly appreciated. Will post pics up tomorrow! Thanks

You probably need a new heater core

Heat is about the same on all cars. Could be a clogged / clogging heater core, clogged line, bad t-stat, or an unbled system.

Start the car run it and blast the heat. Let it run a few minutes and then check both of the heater core hoses. Touch both of them see if one is cold or not, if it is its most likey the core or hose.

Does the engine regulate it's own temp pretty well? if not the t-stat may need replacing.

In the engine bay on the passanger side firewall. You'll see 2 coolant lines one above the other both going into the firewall. They're to the right of the A/C lines going into the firewall
