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 Template:Radiator
  • 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 is braided. Compare to the rear heater hose, which has been replaced with a plain hose.

Removal

Heater was optional, so it is not reuired for safe engine operation. If you wish to remove the heater, how is it done?

  1. Drain engine coolant
  2. Remove heater hose from the fitting behind the cylinder head and plug this fitting with a 1/2" rubber cap
  3. Remove heater hose from the lower radiator hose tee. Plug this fitting with a 1/2" rubber cap
  4. Remove heater from inside car, & plug the two holes in the firewall

Plugs can be purchased at your local auto parts store. They have a selection - just ask!

1/2" plug

Firewall plug

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.

The most elegant way: Remove both lower radiator hoses and the heater adapter, and replace with a single-piece lower radiator hose.

Discussion: POST A-series heater removal

Heater Bypass

If the heater core is leaking, the easiest fix is to bypass the heater. Connect the long heater hose to the back of the cylinder head.

heater_bypass.jpg

You may leave it this way temporarily or permanently -- the engine runs fine either way. Just depends on whether you need the heater for de-misting the windshield.

Alternatives

Maddat sells a Universal Heater Box which is smaller than the stock unit.
