Hi Tom, I was actually talking to Christyn at your office today just firming up my order on a rad for my 70 454! The old one is leaking and the car overheats while sitting in traffic. I can't wait to try out a DeWitt!

Excellent quality! I'm very happy with my Dewitt rad/ fan combo, SP037, in my 80'.

All you have to do is bolt it in and forget about it.I don't look at the temp gauge all the time like I used to.No worries.

ok... Here’s my angle.... As you are very well aware Tom, I purchased one of those eBay radiators, and it fit fine and has run great... for a lot less money....Proposition: Ship me one of your radiators, I will take both outside temps and measure engine temps in my car for 1 week. Then I will install your radiator, run it for a week also taking temps both outside and engine cooling temps. If you radiator cools better, I will publicly announce here how I have been wrong and that yes, yours is in fact better.... but, if there is no difference, or yours does worse, I will announce these results as well. So, if you are so sure of your "superior" radiator, please take me up on this challenge... if you are not really that sure, well.... I would understand that also. If yours works better, I will buy it… if it work worse… you will pay shipping to get it back….And BTW, mine was also 100% made in USA. So, prove me wrong with real world readings, ……. Paul

Actually I dont think it's real appropriate to put a sponsor and Vendor on the spot, but Thats just my view?

I understand how you may feel. But our forum is also a place to separate hype from truth.. I seek truth, not advertising hype... I have no moneys to be made here one way or the other.... Tom stated at the start of this thread that he welcomed other opinions or thoughts... So these are mine.... This is an opertunity to prove me wrong...

See how long the cheap one last.When it plays out see what kind of service you get off of fleabay.Even a good becool radiator will cost you 400 bucks and still won't look close to original.You get what you pay fore.Buy a cheap one and whine about it when it starts leaking two years later or how hard it was to find hoses that would fit it.I don't like doing things twice nor paying for them twice in a short amount of time.Buy what you want.It's a free country.I like stuff that fits and works without re engineering it.Customer service and backing up what they sell means more to me than a cheap price.If the difference in something have to worry with to make fit and one that bolts in. with no problems is a hundred bucks.I'm buying what I know works.I knew when I got into these cars they weren't cheap to own in the first place.

It's not about proving you wrong. It's not about 1 Corvette or 1 radiator. It's about a body of work over a long period of time with a "proven" track record.

Yes you may have a saved a bunch of money and if you did that's great. For others it's not just about saving money. It's about buying a "proven" quality product from a vender that specializes in Corvettes knowing that there is no fitment or performance issues and if there is the company has shown that they stand behind their product. For the Dewitt's supporters Tom has nothing to "prove". He and his company have already done that.

I know it seems like I'm calling you out on this and that's not my intention at all. I'm just trying to show you why many of Dewitt's satisfied customers support him in these threads (at least before it gets locked ).

ok... im not in any way degrading Tom's units or his service. And I do believe both to be top notch. All I am saying is, that "I" believe there are comparable units out there for less money. Mine being one. And I have had mine now for about 2 years and it works great... guess I may have to wait another 2...5...10 years to find out hugh????? There are always options, and there is rarely one only best. I think this is a fair test... and it would require a fair amount of labor on my part, and... if Tom's does cool better... its going to cost me ~$400 and a statement to all about how good it is and how I am wrong....What is so unfair about my proposal? Do we compare heads? cam manufactories? and everything else????!?!?!.... So why can we not compare and test radiators?

to be honest, I hope im wrong, I would love to see my car run 10* cooler or something like that... p

Ok, hold on boys. Let's not turn this into another one of those threads. Paul has an interesting proposal and I think we should discuss it, just not here. Email me or better yet, call me next week 517-548-0600 and you and I can talk about it. I'm at Carlisle now and we'll be pretty busy here for the rest of the week.

That would be a great experiment, but you need to do it in a well controlled environment, like having both radiators in a lab with a temp. controlled coolant passing through them.

You won't regret it - I bought one from Tom about 6 months ago for my '70 454 4-speed and it was perfect fit plus stabilized my temps considerably. No huge temp drop from my OEM but the original was weeping at the seams.

-Hose Connections rarely fit stock radiator hoses correctly ( You will find the hoses now rub on places they didn't before)
-Poor fit of standard mounting brackets (Have to modify at least one upper bracket)
-Poor fit of radiator fan shroud
-Lack of Warranty or Service

Do you want one that fits in correctly with no modifications? DeWitts is the only choice.
Not so Grasshopper

There is another drop in rad that fits the rads support perfectly and the hose connectors come out at the correct angle. I spent large on mine ( I could have bought a kit for much less ) for a custom made setup with an adjustable controller that I can set to come on at any temp and twin 13 in spal fans which really only needs one, I have a switch for the other but have never really needed to turn it on.

I was going to buy Dewitts rad but at the time the rad came with a non adjustable on/off switch. Apparently he had experimented with all kinds of adjustable controllers including a PWM version if I remember correctly. And decided they were nothing but trouble. The problem was I didn't like the on/off temps available in a package deal.

Fact remains there is another drop in aluminum rad that cools a 600HP no problems, and it's it not a feabay rad it's a quality piece. I'm not going to mention the name but I will post a pic, Dewitts products are top notch from what I hear from everyone

Don't worry Tom no one is as stupid as me to spend so much money on a rad package, the cap alone is 60 bananas

Dear Mr Tom DeWitt:
I took the tour of your factory, very impressive! You make everything under one roof in the "Good Old USA" The work stations are spotless and I'll bet you pay your workers a good "living wage" and they appreciate it and do the best work they can.
You original post made reference to "changing perceptions and to justify cost" so lets get to it.
There are lots of posts asking who has the best (whatever)? When it comes to radiators you get the most compliments. It "dropped right in" no more overheat problems and so on. When I install a replacement part and it fits and works I'm a happy camper. What is the cost to have to re-repair in time and money?
You sell the Best and the Best of anything cost more because it's worth it!

Your on line catalogue is easy to read it's nice to find the part quickly.

Paul got lucky that his fit and works well and that's great! but I don't want to cross my fingers hoping that brand X doesn't leak.
The origional post was to justify the cost and after seeing the factory I'll pay a little more for the Best and I'll smile that I kept another American working.
Regards,
PG

yea, maybe lucky... I like to think I did my research by calling the manufactures first,,, numerous e-mails about where it made, cores, core size, fine count etc,,, but, yea.. a little luck never hurts.

That's a pretty poor measure. As long as a radiator has sufficient cooling capacity, your engine temp will be controlled by your thermostat. So what, exactly, do you think your proposal would prove? For example, if your engine only requires 3000 btu to keep it cool and the radiator you now have cools 3001 btu while Tom's cools 5000; you get to say "no difference" and post your 'results'. Where's the upside for DeWitt's? A measly single radiator sale?

It looks like it was made in Glendale, AZ perhaps? If so, then yes, they are very well made and will drop-in. BUT, they don't have the factory appearing tanks either. That may not be important unless you're a purist, but it is something to consider. My 72 has a dewitts.

With regards to using a pulse-width modulator (pwm) for the fan control, I used a Delta Current control unit. The small temp probe fits nicely between the fins in the radiator. No bung required.

+1 on Toms hardware. There are others out there that will work and cost less. But I have not seen any that fit as well or as easy as his. Mine is a custom and it dropped right in with no fartin around with it. My time was worth the difference in price. FWIW I took the cheap one I bought some time before I started making mods and put in a dump truck, its still running good. A Real world, same car and conditions test will be interesting
