Engine Part Identification

[boosd]

Could you please help me identify the part next to the alternator and infront of the oil pan, .....the one that appears to be leaking anti freeze. Thanks

The large thing there is the center under the crank pulley is the oil pump. It's more then likely not leaky coolant, its probably leaking from above and coming down all way there. If you look at the top left of the picture you can see coolant sitting on one of the bolts up there. Something above there is leaking. Check the water pump, hoses and all the fitting that the hoses go to.

Hope that helps

Check the weep holes on the water pump. (I can't remember whether or not the S30 water pumps have them.) I would not be surprised if your water pump was giving up the ghost.

[boosd]

so does the oil pump appear to be leaking given its covered in dried oil/grease?

The oil pump will leak if its missing that thin paper gasket but make sure you know what you're doing if you take it down to check it

I would suggest cleaning it first. Then you might be able to trace the source of the oil that is covering it.

Flushed my cooling system today, got home and checked the radiator.....no coolant, looked underneath the car, coolant dripping of of the same bolt on the oil pump,

heart stopped, grumbles....this can't be good.

Checked around and realized it was coming from the water pump weep hole.......big sigh of relief...............check your water pump
