Heater was optional in the Standard model for most countries. All USA models came with a heater (by law).

Heater Inspection
Heater core:
- Leaks (before removing, check for leaks in passenger area, under carpet, on firewall cardboard, etc)
- Flow (ensure it is not plugged). You can test similar to radiator blocked test
- Clean out debris in exterior of core
Hoses: Check for cracks, overly soft hoses, tight clamps
Flow valve: ensure it opens & closes easily through entire range. Also check linkage for easy and complete movement (before taking apart)
Air ducts: Ensure they are clean and connected properly
Electrical: Ensure fan spins at both High & Low speed
Coolant Thermostat: Test

Heater Hoses
The heater hoses are 1/2 inch inside diameter hose. However, the original Nissan hoses were thin wall. Standard 1/2 inch hose is thick wall and will work but has to be forced through the firewall grommets.
Also, the original Nissan thin-wall hoses had a braided cover like this:
Original long heater hose, replaced rear heater hose
Heater Connector (fits in between the two lower radiator hoses:
Cylinder head fitting (back of cylinder head)
Removal
Heater was optional. If you wish to remove the heater, how is it done?
- Drain engine coolant
- Remove heater hose from the fitting behind the cylinder head and plug this fitting
- Remove heater hose from the lower radiator hose tee. Plug this fitting
- Remove heater from inside car
You can either remove the fitting from the back of the head & put a plug in there, or get heater blank off rubbers & plug them both. You can get these from local Auto stores, it is 1/2" heater hose.
Heater hose plug for cylinder head (as fitted to no-heater models)
Or the simpler way: Run a new longer hose from front to back of engine.
