Dorman Coolant Hose Connector 800-919

When a coolant hose connection needs attention, identifying the right connector matters more than choosing a broad replacement part. The Dorman 800-919 is listed as a coolant hose connector for select Chevrolet and GMC models.

It is a focused part, not a complete hose assembly. That distinction matters when you are deciding what to replace.

The listing names compatible makes but does not spell out the specific vehicles, years or other fitment details. Match the part to your vehicle before buying.

What matters most

The key detail is the stated compatibility: select Chevrolet/GMC models. “Select” is an important qualification, it does not mean the connector fits every vehicle from either make. The product name provides the part number, 800-919, which can help when checking a repair estimate or comparing it with the connector you need.

This is intended for a connector-specific repair rather than a general cooling-system upgrade. If inspection points to the connector while the hose itself is still suitable, a part of this type may be the more targeted approach than replacing a larger hose section. If the hose is also damaged, choosing a connector alone may not address the whole problem.

Keep in mind that the listing does not identify the exact compatible models or provide material, installation or included-component details. Based on the listing, you have a part number and a broad make-level fitment description, not enough information to confirm fit for a particular vehicle by itself.

Best use cases

It suits you if you have identified the coolant hose connector as the part requiring replacement and have a way to confirm that 800-919 matches your vehicle. For example, if a technician points out a problem at the connector during a cooling-system inspection, you can use the part number to check the proposed repair rather than shopping for a complete hose assembly without knowing whether that is necessary.

It may not suit you if you are still diagnosing a coolant issue, need a full hose, or cannot verify the vehicle fit. A connector and a hose assembly are different buying choices: the right one depends on which component needs attention. The product title does not establish that the connector will resolve a leak or other cooling-system symptom on its own.

Tips for day-to-day use

Before ordering, compare the 800-919 part number with the fitment information for your exact vehicle. Do not rely on Chevrolet or GMC make alone. If the vehicle details or the current connector are available to the person handling the repair, use them to confirm the match before work begins.

For a practical repair hand-off, note the part number alongside the vehicle details and ask whether the diagnosis concerns the connector, the hose, or both. That simple check helps avoid treating a connector-specific part as a complete repair kit. The listing gives a country of origin of the United States, but does not provide further details about construction or installation.

Three specific questions

Which Chevrolet or GMC models does it fit? The listing says select models but does not name them. Confirm the exact application before purchase.

Is the hose included? The product is identified as a coolant hose connector, the listing does not say that a hose or other components are included.

Where is it made? The listed country of origin is the United States.

Is it worth it?

The Dorman 800-919 is worth considering when the repair has been narrowed to a coolant hose connector and you can verify the fit for your specific Chevrolet or GMC. Its appeal is its focused purpose and identifiable part number, rather than any stated material or installation feature.

If you still need to diagnose the fault, require a complete hose, or cannot confirm application, pause before choosing it. The fitment information supplied here is too broad to settle those questions, so the best buying decision depends on matching the part number to the vehicle and the repair actually needed.
