2003 Chevrolet Suburban 1500 Q&A
2003 Chevrolet Suburban 1500 Question: Where is oil pressure switch located on the engine ? 4.3l V8 engine.
No 4.3L engine option for the Suburban! You most likely have the 5.3L. To change this part requires special tools, some knowledge and skill that most diy persons do not have. It is located at the rear of the intake manifold next to the firewall atop the engine block. Fairly inaccessable without proper tools and skill. Suggest having this work performed by a mechanic or a car savvy buddy. It is most likely your problem though! - pushrod
