Product Number: 11142N
The WAI 11142N is a brand-new 12V 125A alternator. It is built to replace VALEO original-equipment units, including references TG12C027, TG12C042, TG12C045, TG12C048, TG12C084, TG13S018, and TG13S021 — seven VALEO OE numbers in total. Designed as a direct-fit replacement, it carries the IR/IF (internal regulator/internal fan) design that matches the original VALEO specification across Chevrolet, Pontiac, and Saturn applications.
The unit outputs 125 amperes at 12 volts and rotates clockwise, with an S6 pulley configuration to match the OE belt drive arrangement. The IR/IF design integrates the voltage regulator inside the unit, keeping installation clean and straightforward. Lester numbers 11141 and 11142 are associated with this alternator, providing an additional cross-reference point for workshop catalogue look-ups.
Fitment covers 13 applications across Chevrolet, Pontiac, and Saturn, with confirmed fitment including the Chevrolet Malibu (2006–2007), Pontiac G6 (2006), and Saturn Aura (2007–2008). Always verify against your vehicle's engine variant and existing alternator reference before ordering.

A. The WAI 11142N replaces seven VALEO OE alternator references: TG12C027, TG12C042, TG12C045, TG12C048, TG12C084, TG13S018, and TG13S021. If your existing unit carries one of these numbers, this is the direct replacement. You can also search our cross-referenced catalogue by OEM number to confirm suitability, or ask Simon if you need further assistance.
A. This alternator fits 13 applications across Chevrolet, Pontiac, and Saturn, including the Chevrolet Malibu (2006–2007), Pontiac G6 (2006), and Saturn Aura (2007–2008). Use the selection widget to match your exact make, model, and engine variant, or search by OEM number in our catalogue. Every fitment shown is backed by our Fit Guarantee.
A. The WAI 11142N is a brand-new 12V, 125A alternator with clockwise rotation and an S6 pulley. It uses an IR/IF (internal regulator/internal fan) design, matching the original VALEO unit's layout. Lester references 11141 and 11142 are associated with this part for workshop catalogue identification.
A. IR/IF stands for internal regulator/internal fan. This means the voltage regulator and cooling fan are both built inside the alternator housing — exactly as on the original VALEO unit. When replacing an IR/IF alternator, you must fit another IR/IF unit; fitting an externally regulated type would not be compatible. The WAI 11142N matches the OE IR/IF design throughout.
A. The WAI 11142N is supplied brand new — not reconditioned or remanufactured. It is manufactured to VALEO OE specification and ready to fit straight from the box.
A. Yes — ask Simon, or WhatsApp our team on 07754 288583 with any questions about specifications, suitability, or compatibility.
A. Yes. Every vehicle and OE cross-reference shown for this part is checked against manufacturer data and backed by our Fit Guarantee. If it is not right, our Fit Guarantee or hassle-free returns have you covered.
