• Corrosion, impact, or blockage due to environmental or chemical exposure

Warranty Busters: Costly Mistakes to Avoid

Protect your investment by steering clear of these common errors that could void your warranty.

1. Avoid Stripping Threads

When installing a new oil cooler fitting, ensure the threads are properly aligned before tightening. Forcing a misaligned thread can cause stripping, leading to warranty issues.

2. Prevent Electrolysis Damage

Electrolysis from stray electrical currents can corrode the aluminum core, leading to premature leaks and system failure. Always ensure the vehicle or equipment is properly grounded to prevent the heat exchanger from becoming a conductor. Electrolysis-related damage is excluded from warranty coverage.

3. Stop Erosion Before It Starts

Damage to the filler neck or hose connections caused by water, steam, recycled antifreeze, or unauthorized additives is not covered under warranty. Always use OEM-approved/specified, uncontaminated coolant to maintain system integrity.

4. Maintain Proper System Pressure

A well-functioning radiator performs best within a balanced system. An over-pressurized radiator often signals a larger mechanical issue, such as a blown head gasket or, in rare cases, a worn radiator cap. Always replace the radiator cap when installing a new radiator. Over-pressurization may damage the radiator and void warranty coverage. A blocked DPF (Diesel Particulate Filter) can result in issues with the radiator. Similarly, if the EGR cooler is blocked, both the radiator and CAC (Charge Air Cooler) will be affected.

5. Keep Chemicals Away from Your Radiator

Exposure to fertilizers and other chemical catalysts accelerates deterioration, which is not covered under warranty. Keep your radiator away from such substances. For example, in agricultural environments, radiators used near fertilizer storage or spraying equipment may be exposed to ammonia-based compounds. When materials under tensile stress, such as aluminum or copper alloys in the heat exchanger, are subjected to airborne chlorides or ammonia, there is a significant risk of ammonia stress corrosion cracking (ASCC).

6. Ensure Proper Installation

When removing the old radiator, carefully note bolt placements. Using the wrong bolt size, especially one that is too long, can cause damage and void your warranty.

7. Use Compatible, Contaminant-Free Coolant

Coolant contamination, whether from oxidation, mixing incompatible formulations, or system rust, can severely damage your radiator or cooler. Only use manufacturer-approved coolant. Contaminated systems can cause premature failure, which is excluded from warranty protection.

8. Handle Shipping Damage Correctly

If your product arrives damaged, do not install it. Document the damage and file a freight claim with the carrier immediately, along with wording on the Bill of Lading document. Warranty coverage does not apply to shipping-related damage. If returning a product to Dolphin Heat Exchanger, ensure it is securely repackaged to prevent further damage in transit. In certain scenarios, Dolphin may request to bring back the damaged unit.

9. Pack and Stack for Safe Transport

To ensure safe transport, always use secure packaging and stack boxes vertically for maximum protection. Proper packing reduces the risk of damage, preventing additional costs such as re-boxing fees.

Dolphin Heat Exchanger – Freight & Damage Claim Policy

At Dolphin Heat Exchanger, we are committed to reliable service and product integrity. In response to increased restrictions and evolving policies within the freight industry, this Damage Claim Policy outlines the steps and conditions required to successfully submit and process freight-related damage claims. To ensure timely and successful resolution, please make sure all personnel receiving shipments are familiar with this policy.

In response to changes in the freight/shipping industry over the last few years, Dolphin Radiator has been forced to amend the way damage claims are processed. Dolphin’s current Damage Claim Policy (adopted in July of 2022) is detailed below.

To receive expedited damage claim processing, please ensure that anyone involved in receiving shipments on behalf of your organization is aware of this policy.

Common (Ground) Carriers

Examples: UPS, FedEx Ground, GLS, SpeeDee, etc.

If your shipment arrives visibly damaged:

• Do NOT refuse the package
• Sign for it as “damaged” when receiving, even if the driver leaves without collecting a signature, on the BOL
• Notify Dolphin Heat Exchanger within 24 hours of delivery via email or phone
• Include photos of the package and product damage

Single Order Truck (Pallet) Carriers

Examples: FedEx Priority, Southeastern, Central Transfer, RLS, etc.

To process a claim, the following conditions must be met:

• The Bill of Lading (BOL) must be signed and clearly marked “DAMAGED” by the receiver at the time of delivery with the driver’s signature
• Dolphin must be notified within 24 hours of delivery to initiate a carrier claim
• Do not refuse the shipment. Even if the packaging appears intact, inspect thoroughly. If any damage is visible to the box or product, ensure it is noted on the BOL before signing
• Claims cannot be processed if the BOL is clean or if notification is delayed beyond 24 hours

Stock Order Truck Freight

We understand stock orders are received and stored differently than single-order shipments.

• If damage is visible at delivery, follow the LTL instructions above
• For concealed damage, you may notify us within 7 days of delivery
• Claims may still require photographic documentation

Photographic Documentation (Required)

To support all damage claims, please include:

• Clear photos of external packaging damage
• Images of product damage (close-up and wide shots)
• Photo of the shipping label
• Image of the BOL with damage notation (if applicable)

Dolphin Heat Exchanger is not liable for damage claims that do not meet the criteria outlined in this policy. Carrier terms and freight claim procedures govern all third-party freight claims. This policy does not modify or extend product warranty terms.

For questions about this policy or if you need assistance with a damage claim, call (844) 536-5744

Return Policy

At Dolphin Heat Exchanger, we are committed to providing exceptional service and support. We understand that there may be times when a product needs to be returned due to reasons such as incorrect orders, shipping damage, or warranty concerns. The following return policy outlines the process and requirements for all types of returns. Please read this information carefully before initiating a return request.

Please note that issuance of full credit, including reimbursement for freight or drop-ship charges, is not guaranteed. All returned products must pass inspection and meet return criteria to qualify for credit.

We accept returns for active, resalable condition products (new and unused), within 30 days of the original purchase date. Returns will not be accepted under the following conditions:

• The product is discontinued or obsolete
• The product has been opened, installed, or used
• The product is missing its serial number or original packaging
• The product was custom-made or special-ordered without prior return authorization
• Deductions may be applied to the return credit, or credit may be denied altogether if items are missing or damaged

For replacement orders, standard freight charges will apply. In cases of approved warranty returns, freight reimbursement may be provided after inspection and approval.

An RMA (Return Merchandise Authorization) number is required for all returns. To avoid delays or re-boxing fees:

• Do not write the RMA directly on the product packaging
• Place the RMA number clearly on a separate label or paper attached securely to the package

A credit will automatically be applied to your account through the original method of payment at the time of sale, excluding the original shipping cost and/or call tag freight-back costs.

Dolphin Heat Exchanger is not responsible for returned parts damaged in shipping or products returned without an RMA number.

All heavy-duty truck products purchased after August 1, 2019, include a limited warranty of 2 years or 250,000 miles, whichever occurs first. Please review the full warranty policy for terms and conditions.
