FAQ for wholesale service

Q. "What type of warranty do you offer?"
A. RadiatorLand prides itself in being one of the few online radiator shops to offer you an UNLIMITED lifetime warranty. That means your radiator is covered for life. Simply contact us, we'll process your warranty and get you back on the road the very next day.

Q. "Why does a warranty matter?"
A. If a company provides you with a limited warranty or no warranty at all, odds are the quality is poor and they fear they may have to replace every radiator that goes bad. In addition to being the ultimate in customer service, RadiatorLand guarantees an UNLIMITED warranty with every radiator. This tells you a lot about the quality radiator you are about to receive.

Q. "How do I know if I need a new radiator?"
A. If you're having cooling or AC problems, have the system checked by someone who is qualified to diagnose the problem. You may not need to replace anything at this time. However, beware of quick-fix radiator welding and re-cores. They offer extremely temporary solutions to your problems, and are almost NEVER guaranteed past a few months. Our parts are guaranteed for LIFE.

Q. "What brand is this radiator?"
A. We stock several different major brands, all with Lifetime Warranties, and all built to OEM specifications for fit and quality. These brands include Modine, Visteon (Ford OEM), Valeo (Chrysler/Dodge OEM), Behr (Mercedes and BMW OEM) CSF, Go/Dan Industries (GDI), and Koyo (Honda/Acura OEM).

Q. "Where is the nearest location to me?"
A. We have 3 locations in the Santa Clara area if you want to pick up the radiator yourself.

Q. "What type of payments do you accept?"
A. We accept almost all types of payment. We can accept Discover, MasterCard, Visa and American Express. If you do not own a credit card, we are also equipped with the latest technology to process checks via phone (call us for details).

Q. "What if I am not satisfied with my experience?"
A. It's as simple as a phone call or email. We are not satisfied until you are. We will do everything possible to ensure you are satisfied.

FAQ for retail service

Overheating usually occurs for one of the following reasons -

1. Insufficient amount of coolant in the system.
2. Defective or improperly adjusted drive belt.
3. Blocked radiator core.
4. Dirty or restricted radiator grille.
5. Faulty thermostat.
6. Improperly functioning fan.
7. Improper pressure. Have your radiator cap pressure tested by a gas station or repair shop.
8. Incorrect ignition timing.
9. Defective water pump.
10. Wrong grade of engine oil.
11. Inaccurate temperature gauge.

Overcooling usually occurs for one of the two following reasons -

1. Faulty thermostat.
2. Inaccurate temperature gauge.

External Coolant Leakage usually occurs for one of the following reasons -

1. Deteriorated or damaged hoses, or loose clamps at the hose connections.
2. Defective water pump seals. If this happens, water drips from the weep hole in the water pump body.
3. Leakage from the radiator core or header tank. If this is the case, the radiator must be professionally repaired.
4. Leaking engine drain plugs or water jacket freeze plugs.
5. Leakage from damaged gaskets or small cracks.
6. Damaged head gasket. To verify this, check the engine oil condition.

Internal Coolant Leakage usually occurs for one of the following reasons -
Note: You can detect internal coolant leaks by examining the oil. Check the dipstick and inside the rocker arm for water deposits and milkshake-like oil consistency.

1. Leaking cylinder head gasket. If this occurs, test the system pressure or remove the cylinder head and inspect.
2. Cracked cylinder bore or cylinder head. If this is the case, dismantle and inspect the engine.
3. Loose cylinder head bolts.

Abnormal coolant loss usually occurs for one of the following reasons -

1. Overfilled system.
2. Coolant evaporation due to overheating.
3. Internal or external leakage.
4. Faulty radiator cap. If this is the case, have the cap pressure tested.
5. Engine compression is pressurizing the cooling system. A cracked head or block, or leaking head gasket (s) could cause this.

Poor coolant circulation usually occurs for one of the following reasons -

1. Inoperative water pump. To test, pinch the top radiator hose closed with hour hand while the engine idles, then release. If the pump is working properly, you should feel a surge of coolant.
2. Restriction in the cooling system. To fix, you should drain, flush, and refill the system. If necessary, remove the radiator and have it reverse flushed or professionally cleaned.
3. Loose water pump drive belt.
4. Sticking thermostat.
5. Insufficient coolant.

Corrosion usually occurs for one of the following reasons -

1. Excessive impurities in the water. We recommend you use soft water, rainwater, or distilled water.
2. Infrequently flushed and drained system. You should regularly drain and flush your cooling system to maintain optimum functioning and prevent corrosion.
