I took my 2005 base C6 into the shop and was told my radiator had a leak and would have to be replaced. at the moment money is tight and looking online i have found replacement for $200-300, instead of the $800 the dealership quoted. my question is, are the cheaper radiators a feasible option? and how hard is it to replace yourself on a scale of 1-10 and 10 being the most difficult.

It depends on which radiator you have. I would say it is about a 2 or 3 if you do not have the oil cooler version of the radiator. If you have a radiator without the cooler lines, I have a used one that I purchased from another member for $50.

Who have you gotten quotes from? Have you tried radiator.com?

Its about a 2. If you don't care about originality, take a look at the aftermarket ones. The OEM radiators are aluminum with plastic end tanks. Not that exotic, so there should be pretty good aftermarket ones available. I bought one a long time ago and it was just thinner by a fraction. Not enough to make a difference, in my opinion, as there was plenty of capacity.

Find out if yours can be fixed. Most good shops can fix just about any radiator.

I've got a radiator out of my 2008 collectiong dust in my garage. Took it out at about 22k miles to install a DeWitts. You can have it for $100 plus whatever UPS charges to ship it if you like.

If you do a search for some of the DIY cam installs, certain threads will give you directions on R&R the radiator. It's not very difficult.

I've got my stock Z06 radiator since I upgraded to a DeWitt's if you are interested. It has provisions for the trans oil cooler, but you don't have to hook that up.

I thought the new radiators with plastic tanks were "throw-aways" and could not be fixed?

The tank can be replaced and the rest fixed.

Cool. In the old days they never replaced the plastic tanks, it's good to know they can do that now. What does it cost to rebuild an aluminum/plastic radiator?

Is it worth replacing with a Dewitts radiator? I've learned that the newer radiators with the plastic tanks are only good for a few years and they're disposable-not worth repairing. Figure when it's time to replace the radiator in my C6 I'd upgrade to a larger radiator for better capacity and cooling.

I just had my radiator on my Z replaced w/a Dewitts. Its worth the peace of mind in South Fl traffic with the A/C running.

I vote for DeWitts Too!

Best place to pick up a Dewitts radiator?

I have to replace my LS3 Z51 radiator - how many hours does it usually takes to replace it? I will buy a LS7 radiator, that should fit?

Has any one infos for replacement?

Thanks from Europe (Austria)

I put a dewitts radiator in my C5. All alluminum. Very good radiator IMO. If you can swing it get the dewitts but they will run about 6 to 700 dollars. If you get a cheap one you might or might not have problems installing it or it might not last, but you get what you pay for. Not hard to replace yourself if you have some mechanical skills.

Get an exact replacement if you don't want possible problems. Different models used different radiators. The trans cooler/oil cooler lines have to be the same type of connector in the same location as stock.
