Check which engine you have
The 1GM and 1GM10 are closely related, but not every part fits both engines. Differences can also occur between the 1GM, 1GMC, 1GML, 1GM10 and 1GM10C.
Check the complete model designation on the engine plate before ordering. Compare the original part number with the information on the product page whenever possible.
If you’re unsure, send us the engine model, serial number and any number shown on the old part. A clear photo can help too. We’ll help you check the correct part.
