Stant 27003 Thermostat Gasket (BU 3) – Original Stant Packaging, from Don's Own Shelf

Keep your car or truck on the road with a genuine Stant 27003, the multi-fit Stant thermostat gasket listed for Datsun and Nissan four-cylinder engines and the 2.8L inline-six diesel, 1975–1997: the B210, F10, 210, 310, 510, 610, 710, 200SX, 810 and Maxima diesel, Sentra, Stanza, Pulsar NX, NX and the 1995–1997 Nissan 200SX. It's a multi-fit gasket: a shaped gasket with a large round center opening, several bolt holes and an ear. You rotate it until the holes match your housing, then trim off what you don't need.

Key Features

• Part Number: Stant 27003 (single gasket on a Stant BU 3 card)
• Type: pre-cut, multi-fit engine coolant thermostat (water outlet) gasket
• Design: a shaped gasket with a large round center opening, several bolt holes and an ear
• Condition: from Don's own shelf, still sealed in original Stant packaging (see the photo)
• Series: Stant's "BU" cards are a different series from the "BB" cards used for the 271xx gaskets

Stant's own printed application catalogs (1928–1994 and 1995–2017) don't list the 27003. The vehicle list below comes from parts-catalog compatibility data for the Stant 27003 (162 vehicle lines), so treat it as a strong lead and confirm the bolt pattern on your housing.

Compatible Makes & Models (from parts-catalog data)

• Datsun (1975–1983): 200SX (1977–1979), 210 (1979–1982), 310 (1979–1980, 1982), 510 (1978–1979), 610 (1975–1976), 710 (1975–1977), 810 (1981), B210 (1976–1978), F10 (1976–1978), Maxima (1982–1983)
• Nissan (1982–1983, 1987–1989, 1991–1997): 200SX (1995–1997), NX (1991–1993), Pulsar NX (1988–1989), Sentra (1982–1983, 1987, 1991–1996), Stanza (1983)

Note: Always verify fitment for your specific year, make, model and engine, then match the bolt pattern. The full engine-by-engine list is in the fitment appendix below. If you have your old gasket, compare its shape, opening and bolt holes with the photo, or just ask Don and Kathy.

Price is $9.95 plus $3.00 for shipping. Don and Kathy offer a fair deal for this. Buying for a club, a shop, or a whole fleet of project cars? Even better.

At present I have a total of 8 of these Stant thermostat gaskets number 27003 if you want more even some with different numbers let's talk.

The Stant 27003 Thermostat Gasket: One Gasket, Several Bolt Patterns

Thermostat gaskets are small, but they decide whether a cooling system stays dry. When the thermostat housing comes off a project car or truck, the right gasket is the quiet part that keeps the job from turning into a second trip to the parts counter.

The Stant 27003 takes a different approach from most Stant gaskets. Instead of one gasket cut for one housing, it carries several bolt patterns on one piece. Stant's installation instructions on the back of the card:

1. Wipe oil, water and foreign material from the thermostat mounting surface on engine and on thermostat housing.
2. Place thermostat into engine block or water outlet housing, whichever contains the shallow recess (counterbore). NOTE: Copper pellet of thermostat must face towards the engine.
3. Rotate the gasket about the opening lining up the thermostat and mounting bolt holes in the gasket with the matching holes in the engine or outlet housing.
4. Replace housing and tighten bolts evenly. Trim excess gasket material.

How It Differs From Its Neighbors Not the same as Stant 27103. The 27003 comes on a "BU 3" card and is pre-cut. The Stant 27103 comes on a "BB 3" card, and that card reads "Blank Gasket Material. Cut Gasket Material To Fit Your Application": it's a 3-1/4 by 3-1/2 inch blank sheet. Don's Obsolete Auto Parts carries both, and a few Nissans show up on both lists, so pick the pre-cut 27003 if you want a ready-made multi-fit gasket and the 27103 if you'd rather cut your own.

Stant's printed catalogs cover many of these same Datsun and Nissan engines with later, dedicated gasket numbers. The 27003 is the multi-fit alternative: one gasket with several bolt patterns that you rotate and trim to fit.

Buying Tips

• Match three things before ordering: year, model and engine.
• Compare the bolt pattern: the 27003 has a large round opening and several bolt holes, so line it up with your housing and trim the excess.
• The vehicle list is parts-catalog data, not Stant's printed catalog. If your housing doesn't match any of the patterns, ask before you order.
• Keep the Stant card with the part for authenticity.
• Restoration shops, clubs and collectors can ask about quantity pricing.
