DEI - Radiator Relief - Works like Water Wetter but better

NIZMOZ · 05-15-2009, 11:58 AM

Since a few of you are having overheating issues, this might help the problem a little as well.

Nissan Sport sent me some of this product a while back to test for them. I was very impressed how well it worked compared to Redline Water Wetter that I have used in the past. This stuff does not foam up like Redline's does and foam is a bad thing in the coolant system.

Review the product and give it a try. I believe Pep Boys carries it in stock at some locations and it is pretty reasonable. My car has had it in the coolant since it was new. My needle did drop slightly after this was installed. I have been to many track events, and the temps stayed normal except one event that it was 100+ degrees out and the ground was 120+. My car saw a little raise in temp but not much.

Nissan Sport did a article on this a while back so you might be able to find it.

Motul also makes their own solution too:

This seems more appropriate for our cars.

Heater Hotter

Read this...I don't think you want this.

Heater Hotter™ formulated specifically to accelerate the transfer of heat from engine to cooling system in frigid climates that otherwise increase engine wear. Heater Hotter's™ unique formula allows your vehicle's heater to warm up 50% faster in even sub-zero temperatures and is safe to mix with all types of anti-freeze. Just simply add to your radiator.

Ignoring the part about freezing temperatures which is irrelevant from the engineering perspective, it is exactly what we want. It appears to be designed to accelerate the transfer of heat from the engine block to the coolant. Now if there was only a way to help accelerate the heat transfer from the oil to the block we would be all set.

No it is not. This allows the coolant to get HOT FASTER by transferring the heat of the engine to the coolant faster, which could also allow the engine to get HOTTER than it should. You want something to keep the engine cooler not hotter. This just speeds up the coolant temps so you get heat faster and will not keep the coolant cooler.

I really want the proper solution versus a stop-gap-wait-n-see-wtf-Nissan-is-going-to-do solution.

I think you're failing to understand the overheating problem the car has. The oil (and in theory the engine block) overheat but yet the coolant always remains at a neutral temperature. The data has been showing that the coolant always remains between 180 and 195 no matter how hard you beat on the car, which means the coolant system is capable. The oil on the other hand passes 260 with ease, yet the coolant is failing to do its job of absorbing the heat from the block. So by increasing the efficiency of heat transfer from block to coolant, the oil would cool faster and the heat would be transferred to the coolant where it can be easily dispatched by the radiator. It wouldn't make the car run hotter, it would actually make it run cooler by trading oil temp for water temp.

Edit: I'm sure from an engineering perspective both products are nearly identical. They are both designed to accelerate the transfer of heat from metal to fluid or fluid to metal (radiator).

Thanks for bringing all the products to my attention. i will see if i can get one localy.
