Their should only be two bolts holding it in. If you want to remove the oil cooler lines and thus not use the oil cooler system at all you must do the following and not put plugs into the inlet and outlet ports. Diconnected the two oil lines, remove the oil filter adapter. Install the proper oil pressure regulator ( a dealer part) onto the block where the oil filter swrews on. If you only plug the ports in the original oil cooler adapter you will starve the engine of oil pressure since the oil flow will be blocked off. Required adapter GM #3952301 and the gasket GM #31028280.
1 gm = 1000 milligrams therefore 3.1 gm = 3100 milligrams

I assume you are working on a 350 Chevrolet small block with the factory GM oil to water cooler in the radiator? Why remove the oil cooler? With the engine cold, remove the oil filter from the adapter. Remove the lines from the remote cooler adaptor first. Then look up into the cavity (above where the oil filter screws on) and you will see two bolts. Remove these two bolts and the adaptor will come off. Obtain a regular GM (Chevrolet small block) oil filter adaptor from any non-oil cooler application with the bolts. There are a million places to get these. Bolt the new adaptor in place, screw on a new oil filter and off you go. The factory filter seals against the flat surface of the engine block and the filter now screws onto the oil filter adaptor instead of the cooler adaptor. You may want to remove the oil lines to the radiator and plug the oil cooler openings in the radiator. If the oil cooler is already or begins to leak you will loose coolant through the cooler openings. mlynch003@yahoo.com
I've done it multiple times and never had any issue. Absolutely no change in oil pressure.
There are 3 coils on all 3100 gm
I BELIEVE it is 4 quarts. Put in 4 quarts, and then check your dipstick. I know 3100's and 3400's are 4.5quarts but the newer engine is different.

The General Motors 3100 family of after 1996 underwent a changeover to interference designs. This standardized GM powertrains design across multiple platforms such as the 3400 and 3500.
