Throttle Body: Service and Repair
Throttle Body Cleaning
CLEANING CAUTIONS
All TBI component parts, with the exception of those noted below, should be cleaned in a cold immersion cleaner such as GMX-55 or equivalent.
CAUTION: The Throttle Position (TP) sensor, Idle Air Control (IAC) valve, pressure regulator diaphragm assembly, fuel injectors or other
components containing rubber, should NOT be placed in a solvent or cleaner bath. A chemical reaction will cause these parts to swell, harden or
distort. Do Not soak the throttle body with the above parts attached. If the throttle body assembly requires cleaning, soak time in the cleaner should
he kept to a minimum. Some models have hidden throttle shaft dust seals that could lose their effectiveness by extended soaking.
1. Clean all metal parts thoroughly and blow dry with shop air. Be sure that all fuel and air passages are free of dirt or burrs.
2. Inspect mating casting surfaces for darnage that could affect gasket sealing.
Thread-locking Compound
Service repair kits are supplied with a small vial of thread-locking compound with directions for use. If material is not available, use Loctite 262 or
equivalent.
CAUTION: In precoating screws, do not use a higher strength locking compound than recommended, since to do so could make removing the
screw extremely difficult, or result in damaging the screw head.
