FAQ - GENERAL RADIATOR & COOLING pg.2

16) My car runs hot on the highway and boils over in traffic? Is this a radiator problem?
A hot running car needs to be properly diagnosed. It may be caused by a defective or undersized radiator; however, there may be many other causes such as a defective thermostat, water pump, low coolant, wrong pulley ratios, etc.

17) How do I mount one of your race radiators?
Saddle mount with rubber isolators is our recommended mounting for a race radiator.

18) If I put a screw through the sideband, will it be strong enough to support the weight of the radiator?
You must use enough screws to support the weight. Make sure the screws do not puncture a tube.

19) Will Griffin weld brackets on the race radiators?
Griffin recommends cradle mounts but will weld brackets to the radiator if specifically requested by the customer. This will require an additional charge.

20) I bought one of your race radiators and it does not have a drain. Why?
Since most racers don’t use a drain, Griffin does not put one on the race radiators. Also, given the variety of chassis, it is impossible to find one location that would suit every application.

21) What is the alloy that Griffin uses?
Griffin uses 3003 as a base alloy. Our braze alloy is either 4004 or 4104. These alloys contain a significant amount of magnesium making them stronger than any alloy that can be used in a CAB or COB (also known as NOCOLOC) process.

22) Do you build triple pass radiators?
A triple pass radiator is not a standard build; however, we can build one to a customer’s specific specifications.

23) How thick is the material Griffin uses for the radiator tanks?
The radiator tank material used by Griffin is between .063 and 0.125" thick depending on the application.

24) What is the distance between the tubes?
The distance between the tubes is 0.351" at the inside and 0.430" at the outside.

25) What is the height inside the tube?
The height at the inside of the tube is 0.0511".

26) Why is Griffin’s core glued to the tank?
Griffin’s core is always welded to the tank. Griffin does not use any glue in the manufacturing process.

27) How tall is your filler neck?
Approximately 7/8" tall.

28) How far does the gambler neck extend toward the engine?
It varies with each design.

29) How long are your hose connections?
Hose connections are generally about 1.75". This can vary according to application.

30) What is the inside diameter of a -16 AN fitting?
The diameter of part -16 AN fitting is .840 I.D. (slightly larger than 3/4").

31) At what temperature will the epoxy melt?
Epoxy will resume curing at 375 degrees F and proceed to over cure.

32) If I weld brackets on your radiator, will it melt the epoxy?
Welding brackets too close to the epoxy may raise the epoxy temperature over 375 degrees which will cause the epoxy to over cure.

32) If I melt the epoxy on your radiator, will it leak?
Epoxy is not used to disguise leaks. It is added for strength and protection; however, epoxy will resume curing at 375 degrees F and proceed to over cure.

33) If I weld brackets on your radiator how do I keep them from melting the epoxy?
Griffin doesn’t recommend welding brackets and by doing so the warranty will be void. If welded brackets are required, Griffin can do so prior to the epoxy process. The epoxy cures at 375 degrees. Welding after epoxy is applied may cause it to over cure.
