Hi, I am replacing the thermostat housing filler neck on my 2008 Hyundai Accent. I have run into a problem. The filler neck I have only has 2 bolt holes while my research shows the thermostat housing filler neck has 3 bolt holes. All part stores and the internet shows the filler neck has 3 bolt holes. Does anyone know if my car could have had an engine swap? if so to what types of engines? I need to find a filler neck part that fits my thermostat housing and can't find anything anywhere since MY parts do NOT match.

My Thermostat housing (note only 2 bolt holes for filler neck on bottom)

Stock thermostat housing.

 

Suggest you check with a Hyundai parts dept. Provide your VIN and they should be able to tell you which belongs in your vehicle.

 

same problem, needs to find the same parte , can you help me... Only two holes
