Good product
Excellent product, no problem installing the Oil Sending/Pressure switch. I was getting an oil leak on my previous switch so I decided to change the switch out. No oil leaks so far. Although, I believe the oil leak was caused by a louse connection on my Oil Filter. So I changed both of the items , the oil filter & the oil pressure switch. Good product and went in a snap!

1 Question
Does a 2005 Chevy trailblazer have a filter behind oil pressure sensor some people I've talked to say is yes and some say no?

The oil filter is below the oil pressure sensor. Not behind on my 2003 GMC ENVOY.

No questions have been asked about this item.
