Upgraded radiator = thicker towards front bumper or engine?
 

Quick question. All these thicker upgraded radiators. Are they thicker towards the front of the car or the engine?

Point is my fan is already right up against my intake piping. The stock fan shroud is huge so I guess I'd have to get a low profile fan.

Next round of mods is cooling. LG oil cooler for sure and maybe radiator if that doesn't do enough.

Dewitts is the same dimension at the top & bottom, only the core itself is thicker, drops right in:thumbs:

How's that possible? I don't understand... Like, it's not taller ? I don't think any are.

The answer is both, front and back. The stock core is 26mm thick and this leaves a gap in front and back for more core. The DeWitts is 52mm

So does the fan not move backwards?

I believe they are saying, the DeWitts' core fills in the "Expansion Area". So fan stays the same

Our fan/radiator combo will clear easily.

exactly, same mounting position in relation to stock. it is much easier to do if you remove the radiator & fan and replace the radiator then install the fan

I'm confused how it wouldn't move since my fan shroud is right up against the radiator.

The fan shroud is mounted to the radiator's shoulders (one on each end). The cores (middle) are thicker and do not affect the mounting position on the shoulders.

Look at the illustration. The cores are thicker, but the shroud does not mount onto the cores. It mounts onto the shoulder (two blue end squares on the illustration).

BTW: DeWitts has a lifetime warranty. I developed a small leak in mine and sent it to them for repair. They repaired it and sent it back at no charge. Note: Only DeWitts can make warranty repairs, do not send to another shop or your warranty will be voided.

Edit: "Tanks sre the proper term not shoulders" LOL

correct it more apparent when you get it out

Do not use radiator zip ties as pictured by LG. Most mfgs will void the core warranty if you do.

Thanks a ton guys

your welcome those spring clamps on the radiator hoses are a BI#$&
:ack:

We wouldn't void warranty on our radiator due to an issue caused by the ties that we supplied...

I had a custom laid forward radiator in my C5 race car and a custom one for our Panoz road race car made by a major Nascar supplier in NC. They treated core zip-ties like a 4-letter word and would void any/all warranties on the core if used. They said in their experience the vibrations/shiting will eventually wear a hole in the radiator tube. Just one data point. That said, I see them used at the track all the time.

I can 100% see them being an issue on a dedicated race car with aero that's sprung to high heaven or on a TA Car/ Nascar as those have a huge amount of vibration. That being said we don't use fans on forward tilt radiators in race cars, application is key in recommendations.

Do all of you guys take out the shroud that goes to the hood? I have heard that actually gets more cooling than having the shroud there. Any lift issues under the hood?

We get rid of them.

I did a quick test at a track day at 105 degrees ambient and my car overheated at the exact same 8 minute mark. But I keep it off anyhow. I tend to believe it's just to reduce chances of snow falling onto the engine. Remember these have to be ok to be sold to everywhere.
