To ensure correct installation, you should:
* Consult a repair manual: A factory service manual for your specific year and model Grand Am is crucial. It will have diagrams showing the exact location of each pushrod and its corresponding valve. Improper placement can cause serious engine damage.
* Label everything: Before disassembly, carefully label each pushrod and its location (e.g., with tape and a number or marker). This will prevent confusion during reassembly.
* Pay close attention to length: Pushrods are often slightly different lengths (though not always obvious). Mix-ups are disastrous. Double-check that each rod goes to the correct location.
In short, there's no magical pushrod order – it's about matching each rod to its specific valve. Use a repair manual and be meticulous.
