I currently have the Dewitts short radiator in my C6. It's been great and has been installed since 2012. The oil cooler needed to be bypassed a few years ago due to leaking at the radiator. I'll want to retain that option moving forward. Now it's leaking coolant pretty bad after bottoming out the front end on a buckle in the concrete. Figured I'd make a new post and see if there are other options out there before I pay a premium for another Dewitts. I will want to run the same dual spal fans.

Reason: update
Think I'll try the CSF. Hopefully it performs as well as.the Dewitts. Im wondering if i can get away with a stock radiator support instead of buying the lowered procharger unit that is currently on the car thats mangled.
Just an FYI - I'm finding out that the short CSF radiator is not stocked. I'm looking at a month lead time. It's fine for me since I rarely drive the car anyway. However if someone needs it right away, keep this in mind.

They are probably custom made to order to help reduce inventory costs.
Update - It's nearly October and I am still waiting on a CSF radiator. I've heard about 5 projected ship dates at this point. One would think they would want to compete with Dewitts, guess not.
On Oct. 1st, I'm cancelling the order and going back to a Dewitts, I might be able to take the car out on one last hurrah before winter.
I'd call now. Tell them about your first radiator and ask for a little pro-rated discount. They are pretty flexible with loyal return customers
Thats exactly what I just did. The sales rep took very good care of me and I should have a radiator to install early next week.
thanks for the advice tom.
Should be up and running soon. Thanks Dewitts for the excellent service and taking care of a previous customer!
In my line of work, it does not go unnoticed!
Really would have liked to try the CSF. The date has even gotten pushed out further now. Manufacturing could use some improvement to be a competitor in the C6 market.
