Primed the filter and cooler during assembly to minimize air in the system when started. The two things I didn't like about the kit was the oil lines could have been a couple of inches shorter. I was also not pleased with the Mocal adapter construction and machine work. I've done engine work in the pass so it was time to get out the die grinder and smooth the oil passage and sharp machine edges, The other thing I didn't like about the adapter was the way the oil filter extension fitting seats on the adapter. You have to be careful when tightening to get the socket fully seated so you don't strip the nut, 6-point socket is strongly recommended. Since all this I found that Mocal makes a new heavy duty more robust adapter for only a few dollars more. I would check the sensor's and wires and make sure nothing is damaged or grounded.
