G37 Engine Parts for the 3.7 Liter V6
What is on this page
Wiring harnesses are the largest group with 102 listings, followed by 81 oil filters, 44 engine control modules and 27 camshaft followers. Crankshaft main bearings, coolant hoses, timing chain tensioners and timing cover gaskets are here too. Many parts are shared with other INFINITI models that use the same engine, so read the notes on each listing. A part listed for the Q60 or the EX37 can still be the right one for your G37 when the notes match your engine and drivetrain.
Camshaft followers come in sizes
The valve train is where part numbers multiply. Camshaft followers are sold by thickness, from 7.94 mm to 8.38 mm in these listings, because the thickness sets valve clearance. 13231-EY00A, 13231-EY03B and 13231-EY05A are three of them. Measure the clearance and the old follower before you order a replacement.
Timing parts and the intake
Timing chain tensioners 13070-JK21C and 13070-EY00A, camshaft sprocket 13025-EY02B and timing cover 13500-EY03B are on the list, along with the gaskets for the timing cover. Intake manifold 14010-EY02A comes with its gasket and carries notes for the G37, Q60, Q50 and other 3.7 liter models from 2012.
Drivetrain changes the part
Engine cradle 54401-JK500 is listed for AWD cars, with notes for the G25, G35, G37, Q60 and Q40, while 54401-JK02A covers the rear wheel drive versions. Engine mount bracket 11272-4GA5A is an AWD part, and coolant pipe 21022-JK21C has a note for 3.7 liter cars without the sport package. A G37x and a rear wheel drive G37 can need different parts in the same spot.
Before you order
Trim matters even for covers: engine cover 14041EY05A is listed for the 3.7 liter without the IPL model. For a rebuild, piston ring set 12033-JK20D is a complete standard size set. Search by VIN, compare the notes, and plan on new gaskets whenever a cover comes off. If an oil leak at the timing cover or a valve cover is the reason the engine is coming apart, order the seals together with the main part.
