Questions & Answers

I want to know if this fits on a 2009 Chevrolet Impala SS V8 5.0. Would you mind sharing the 3 liters?

It would be best to look up this item on the Advance Auto website and compare the part number to see if it will work. I had no problems fitting my 2006 impala v8

What does this item actually do? Is it a radiator cap that delivers 18 psi?

In short, yes. There are two parts to this item - a radiator cap and a psi

It was a big hassle to replace an old cap

5/5

I had a leaking problem with my old cap. There are more threads on this cap, which makes it much more durable. The first time I tried it on, I thought it was the wrong cap, but after looking closer and comparing it to the old one, I found out it did not leak. I had a leak in my old cap that caused my water pump to go out, and it ended up leaking onto the clutch for my AC compressor! Buying a new compressor clutch for under 80 dollars and installing it without evacuating the system was very easy for me. Now all is okay with the new cap because the old one caused a lot of problems. I'm so excited!.

What I have written is the exact replacement of what I had written

5/5

I couldn't really add anything else The cap is for a radiator. just a replacement for the stock one. Take one off, toss it, and take a new one on. There is no more leak.
