I see you're back! Thanks for the response. I'll look up the price on IoS website. Have you replaced your radiator yet? Yeah I think that I'm going to go with what's in here now. I need to get this replaced asap since I'm on the road a lot. I'm thankful that the leak isn't large now.maxnix wrote:Hello Joe!
There are brass ones aftermarket, but I would stay with aluminum considering how much there is in the engine and how different valance metals can interact through an electrolytic solution. I wonder if there is a sacrificail anode like on the G60?
Well if I were to purchase from the dealer then it would be almost $600 but purchasing from IofS...it was a little cheaper. I went to Advance Auto Parts website just to look at radiators and theirs is $280. I went to eBay and they are around the $100-150 range but it's with brands that I've never heard of or auctions with wording that isn't spelled correctly. More important, if something were to go wrong, I wouldn't be able to get in touch with them since it's an online auction.BCC93QT wrote:Honestly, I thought it would run far past 500. When my MAF went out on me they quoted me at $435 or something for a brand new one.

Only expensive test equipment can tell the difference during the first year or two.
Really depends on the longevity desired.
My oem rad lasted 10 years and I expect 15-20 years out of my $900 custom thick all aluminum unit.
Some times getting 1-2-3 degrees improvement can cost multi hundreds.
That makes sense but I just can't see myself spending $900 on a radiator. I guess that I'm going to purchase one from AAP with the lifetime warranty. If something happens, I'll just get another one. I guess I should change out the thermostat while I'm at it huh?Q45tech wrote:Generally aftermarket rads save cost by thinner metal and plastic, fewer fins per inch etx.

Do you have data to back up your decrease in efficiency numbers; if so I would like to see? I know multiple people who have purchase non-oem radiators and they are not changing them out every 3yrs. I will go ahead and purchase the radiator from AAP and if it goes out in 7yrs, I'll just get another one with the warranty. 7yrs from now, my Q45 would be downgraded to just a work vehicle since I would've purchase a new vehicle by then. The Lexus GS350 is looking very sexy now and days...Q45tech wrote:THE POINT is the $199 replacements can last a few years [maybe even 7 years] but you must be sensitive to slow annual decreases in efficiency. Most people don't care or are immune to a few degrees rise.
AS opposed to a $900 unit I would probably feel safer in replacing a $199 unit every 3 years {<50k] if I wasn't sure I would be keeping the Q for 10 years more!
Net net the efficiency would end the same.
I did. I don't have anything from you. Don't send it to that old gapac.com address. I don't work there anymore. My updated email is on my profile.maxnix wrote:Check your email.
The end tanks are the tanks that mount on the ends (or top and bottom) of the radiator. That's the part that's leaking on yours. Sounds like you've made up your mind though...NightRiderQ45 wrote:Q451990...I'm sorry but what are the end tanks? The work involved with what you mention, I think that I could go ahead and purchase a new radiator.
I have my BS in Electrical Engineering so don't get it misconstrued I'm not an idiot. Stop throwing out your MS credential because I can obtain that with an extra 1.5-2yrs schooling...as I chose NOT to since I was offered a great salary/position coming out of college with my previous employer. Everything you stated about aluminum corrosion is true, but you still didn't answer my question. Show me proof that an aftermarket radiator is at least 15% worst than an oem radiator. Show me proof that an aftermarket is built worse than my present oem radiator. Show me proof that my oem radiator will run cooler than the aftermarket. IF you can't present proof then I respectfully tell you to be quiet. I mean every Bachelor of Science in Electrical Engineering knows that you can't pass by assumption but by proof...Q45tech wrote:Almost every Master in Science engineer understands aluminum alloy corrosion and oxidation and it's effects on heat transfer.
All every ________ has to do is look and measure fins and their deformation to see these effects.............without even a microscope.http://www.keytometals.com/Article14.htm
The are 7 major series of alloys and hundreds of sub blends in each series
Couldn't have said it better. With the price you pay for a oem oil filter, you would think that you have the best build/quatily inside of that can...WRONG! Cut that sucker open and see how cheaply it's constructed. Once again price is a poor indicator.qship96 wrote:Yes, but who is to say the factory radiator is better, equal to, or worse than an aftermarket radiator.......price alone is a poor measure as all nissan branded replacement parts are overpriced these days.
Thanks for clearing that up. I don't know of any radiator shops in this area that can do that but Brian sent me some good info for radiators so I think I'll go ahead and purchase the new one.Q451990 wrote:
