Revision as of 06:35, 20 February 2013

Datsun 1200 used a traditional vane-type water pump, driven by the fan belt. The same pump was used from 1966 Datsun B10 to some 1982 Datsun B310. However, air conditioning-equipped models used a different hi-performance pump, and some models used a short-shaft pump.

Comparison

There are two basic water pumps for A-series engines, each of which uses a different pulley and fan.

NOTE: Both setups are exactly the same length block-to-fan, so they interchangeable as a set along with the pump.

1. Short pump with short pulley, spacer and high offset fan

2. Long pump with long pulley and low-offset fan

You can't mix and match these parts, as the short pump uses a different bolt pattern (the spacer is an adapter allowing the fan to bolt up).

Datsun 1200 is long shaft, large pulley (spins slower)
Newer is short shaft with spacer, small pully (spins faster)

Note that the pulley bolts are wider apart in the newer pump
Newer pump has studs for the spacer
Some aftermarkets pumps have a sheet-metal impeller, smaller but more agressive
Genuine Hitachi and Atsugi pumps (both A12 and A15) have a cast iron impeller

Heavy duty water pump installed on all 210s starting with late September 1979 productino of 1980 model year vehicles.

Fan

Datsun 1000 used a metal 4-blade fan. Datsun 1200 uses a tough plastic 4-blade fan of 310 mm diameter (12.2 inch). They are strong and not known to break. Some newer A14 used the same diameter fan but with a negative offset and was used with a spacer. Most newer engines used a 330mm fan with spacer. Datsun 1200 used no spacer, but used a longer water pump. 330mm fan was Datsun 1200 OPTION FOR TROPICAL USE.

Pulley ratio: 1.08
Fan pulley: 129 mm
Crankshaft Pulley: 139 mm

USA dealer option flex-fan

Comparison

There are five diameter of fans for RWD A-series engines:

Small steel fan: 280 mm used on Datsun 1000
Lo-output engine: 310 mm diameter plastic (used on A10/A12/A13/A14/A15)
High-output engine: 330 mm diameter plastic (also B110 OPTION)
PB310 and HB310: 350 mm diameter - thermo, 7 blades
Electric fan: 320 mm diameter, steel 5-blade (some 1980-1982 B310s)

In USA, A/C 1200s got a flexi-fan (fibreglas blades), while B210, B310 used #2 above.

Electric Fan

You can fit the Datsun 310 (N10 Pulsar) fan into a 1200:

The thermo switch is in the lower radiator hose

Presumably the lower temp switch is used with the standard 82C engine thermostat and with A14/A15 OPTIONAL 76.5 engine thermostat "For Tropical Zones" (76.5 was not used with E15S).

And the higher switch was used with standard 82C or 88C "For Frigid Zones" (A14/A15/E15).

B310

The Datsun 210 (B310) "MPG" model featured an electric fan. MPG models had Manual transmission, chassis RSFU, RFN, from Sep 1980 with A14 engine w/o AC:

Like other B310s it used a 13 psi radiator cap.

Others

These are radiator-mounted switches. Instead of the extended-sensor type (extends into coolant flow) for use with a hose adapter they are low-profile type.

B11, N12 fitted the temp switch directly into the lowest part of the radiator, using the same threads M16 x 1.5 as the A-series type.

Pulleys

These are the common pulleys:
- Datsun B110: 129 mm (~5.05") diameter, 2.33" high, locating hub 0.85"
- Datsun B310: 4.22" (~107mm) diameter, 1.74" high, uses spacer, locating hub 1.98"

The long pump (B110) uses a fan with positive offset. The short pump (B310) uses a fan with negative offset, but with a spacer. The overall height of fan from block face is the same for both models.

21051-18000 PULLEY-FAN & WATER PUMP
- Original Style: 1.970 inch bolt centers
- A10, A12, A13, A14, A12A
- B10, B110
- B210 (with spacer)
- B310 to 0779 (with spacer)
  - 11720-18002 BELT-FAN L=838 [For B110]

21051-H9900 PULLEY-FAN & WATER PUMP
- New style: 2.362 inch bolt centers.
- Spacer has 1.970 holes on the fan end
- B310 from 0879
- A12A, A14, A15
  - 11720-H9910 BELT-FAN(987) A12A Cal From 0879 [For B310]
    - replaced 11720-77701 BELT-FAN(980)

The two combos of pump/fan/spacer interchange as a whole combo. The newer type allows the fan to be unbolted while the radiator is still in the car.

Presumably the A-series moved to a small diameter pulley to slow down pumping flow, perhaps to prevent cavitation at high speeds.

A third pulley is the B310 Aircon setup:

21051-H7200 PULLEY-FAN & WATER PUMP (D=103)
- B310
- OPTION A14,A15
- No spacer, but instead a clutch
- 7-blade fan (350 mm)
  - 11721-H7210 BELT-FAN(970)(FOR AIR-CON)
