Multiquip EE42662 Intake Manifold Heater Locknut TAD1240G

The Multiquip EE42662 Intake Manifold Heater Locknut TAD1240G is a genuine OEM fastener designed for TAD1240 series equipment. Sourced directly from Multiquip, this locknut is the exact component specified for the intake manifold heater assembly on TAD1240 applications. Correct fitment is confirmed for TAD1240 models, giving you confidence that this part installs and performs as originally engineered.

Key Features

• Genuine OEM Fastener Grade — Manufactured to the precise thread specification and torque rating required for the intake manifold heater mounting position, ensuring a secure, leak-free connection.
• Direct Drop-In Fit for TAD1240 — Engineered to the original thread pitch and dimensions for the TAD1240 intake manifold heater, so installation seats correctly without rework or modification.
• Confirmed TAD1240 Compatibility — Fitment is verified for TAD1240 series equipment; cross-reference part number EE42662 with your machine's parts manual before ordering.
• Maintains Heater Assembly Integrity — A properly torqued locknut holds the intake manifold heater firmly in position, supporting consistent cold-start performance and protecting surrounding manifold components from vibration-induced loosening.
• Fuel System Safety Relevance — Secure fastening of the intake manifold heater is critical to maintaining sealed intake circuit integrity; a missing or damaged locknut can introduce air leaks that affect engine starting and fuel efficiency.

The intake manifold heater locknut is a critical fastener that secures the intake manifold heater element in place within the engine's air intake circuit. The heater itself warms incoming air during cold-start conditions, helping the engine fire reliably in low-temperature environments — and the locknut is what keeps that component seated firmly against vibration and thermal cycling. When this locknut is missing, stripped, or improperly torqued, the heater can shift or loosen, introducing air leaks into the intake manifold that disrupt the air-fuel mixture and make cold starts difficult or unreliable.
