For a coolant to be most effective, the cohesion between the surface of the engine's metal cooling passages and the actual antifreeze/coolant is necessary. The coolant will then absorb more heat from the engine and expel that heat in a radiator with clean passages. A major intent of antifreeze chemistry is to keep your cooling passages clean. Mike explainedhow a 2-row radiator with a 1 inch to 1-1/8 inch cooling tubes were moreefficient than a 3 or 4 row with smaller tubes. Auto City Classic offers aradiator, part # SL-090A-AT-F, with 1 inch to 1-1/8 inch tubes. The outlet is onthe driver's side which allows a cross flow. Contaminated coolant increase the fluid acidity which wears down the aluminum until leaks start to appear. Collision. As a front-end part, radiators are often involved in collisions. Even if the initial impact does not damage the radiator, smaller leaks in the cooling system can be found afterwards which also warrants radiator replacement. Do Aluminum radiators require special fluid? ??? What do you know? What have you heard? I bought an aluminum radiator for my DD from Petrowerks in Mar of this year, and now it is leaking. No visable damage. Leaks from one of the passes. I called up Petrowerks and talked to Rob't (I If the SCAs are becoming depleted, a supplemental SCA known as coolant conditioner can be added to help boost levels back where they need to be. Conventional coolant does not have a very long life and should be changed roughly every two years. Conventional Coolants. Silicates for aluminum protection; Nitrites for liner cavitation protection

Copper transfers heat better than aluminum. Assuming the radiator design is equal, what you're paying for with aluminum is lighter weight and bling factor.

3 Nov 09 08:09. I have been getting conflicting information from aluminum radiator suppliers. One supplier has told us that the use of non-aluminum compatible antifreeze will eat away the radiator in as little as a few days. Another supplier has told us the worse effect of non-compatible antifreeze is that it will turn to a sludge like substance.
Yes, aluminum radiators usually require special coolants. This is because the radiator fins are made of aluminum and some types of traditional coolant can react with the metal and cause corrosion or rusting. The best way to ensure that your radiator doesn't experience any damage is to use a coolant specifically designed for use with aluminum
Another user on the forum enlarged the 1/8 NTP hole in the 22mm radiator to 1/4 NTP and used a 1/4 NTP x 1/8 NTP reducer. Either way would work. Both has it challenges. And both accomplished the same thing. To get the sending unit just barely in the coolant. If you just put the sending unit in. IMO it just blocks too much of the coolant flow.
The old brass types do a better job. Racers use aluminum radiators to save weight, but that would be kind of silly on a 3500-pound street machine. Besides, if your classic-era car is designed for water only, an aluminum radiator will have a short life unless you run coolant as well, and that puts you back to running hot. Use the Zerex Z05 is the recommended antifreeze for your new aluminum radiator. Dave. Zerex G-05 is a HOAT formulation (hybrid organic acid tech.)that will not precipitate silicates into the cooling system that eventually will clog the radiator passages. Reply Like. Be Cool radiators are made with a quality grade aluminum and are 100 percent aluminum welded. We don't use epoxy on our radiators.". Furnace brazing is when a dissimilar material is used to join metal components. These materials can include copper, aluminum-silicon, silver, nickel, or a variety of materials. Aluminium is recyclable, so if you want to minimise your carbon footprint, then this material is good for you. You can find lots of designs and styles. If you want to know a little more about each of these benefits head to our Are Aluminium Radiators Worth It post that goes through them all in more detail. You can use even car coolants in ATVs as long it is compatible with Aluminum. But remember for long-lasting performance, it is always better to go with ATV coolants that are specific to your engine type. Generally, there are only 2 types of coolants available: Propylene glycol coolant and. Ethylene glycol coolant.
This is due to the fact that they contain 50% demineralized water. As a result, the solution does not need to be diluted before use. Universal coolants contain a low silica content to protect sensitive engine and radiator components from corrosion. Organic Antifreeze. Organic antifreeze is created with the help of Organic Acid Technology (OAT).
It gives your engine and cooling system protection against boil overs, heat damage, and corrosion throughout the year. 2. BMW 82-14-2-209-769 Antifreeze/Coolant. BMW 82-14-2-209-769 Antifreeze/Coolant. $33.39. This is our recommended coolant and comes in one-liter package. Buy Now. Check Latest Price. Maxima is another brand name that you can trust. We love their products, and the company's specially formulated engine coolant is no different.This product's full name is technically "Maxima Coolanol 50/50 Blend Performance" and that's because it's formulated with a cool 50/50 blend of two different things: a radiator fluid that's both a coolant and antifreeze Running straight coolant is an idea whether ethylene or propylene glycol. Propylene seems more popular for what's called non-aqueous systems that most all production has gone to in recent years. This eliminates the aluminum corrosion problem but does require a slightly better radiator as this stuff is not as efficient at heat transfer as water. The radiator in a car should be replaced every five years or 60,000 miles, whichever comes first. This will help keep the engine running at its best and keep the cooling system from malfunctioning. If the radiator is not replaced, it can cause the engine to overheat and damage vital components. 0SRfkt.
