Ya know my GN sat for over 10 years, no good reason other than I had a lot of stuff going on, so I ended up changing all gas lines, pump, gas tank etc. went to drive it and had to fix heater core&*^&%#^&zi. g that done and figured out I'm now home free. wrong!! drove it and radiator is leaking! Dam. I've done a lot of reading trying to figure out what to buy, I'm one of these people that try and keep my car as stock as possible. I read guy have done all kinds of things which to me is ringing the cash register on the value of my car. Sooooooo I decided to go with the replacement with the Alradco unit with both coolers. I'm lucky as my son just bought for me. not here yet but believe this is the best option for me.
