Key Features

Guaranteed fitment for listed Volvo applications
Molded to OE heater hose shape for proper routing and appearance
EPDM rubber resists heat, ozone, and electrolysis-related breakdown
Temperature rating from -40°F to 275°F (-40°C to 135°C)
24-month unlimited mileage warranty

Detailed Description

URO 1378850 is an HVAC heater hose designed for the cylinder head to heater inlet path on select Volvo models. The molded profile supports factory-style routing, which helps maintain clearance and simplifies replacement on Volvo 740 heater hose, Volvo 760 heater hose, Volvo 745 heater hose, Volvo 780 heater hose, and Volvo 940 heater hose applications. The hose material is engineered to handle underhood heat while resisting ozone exposure and internal degradation caused by electrolysis.

What It Helps Address

Coolant leaks at the heater hose connection
Cracked or hardened rubber from age and heat exposure
Poor hose routing caused by a misshaped replacement hose
Heater inlet flow issues related to a damaged hose section
Service delays when the original hose no longer seals properly

Installation Notes

For listed Volvo 740, 760, 745, 780, and 940 applications, this hose is used at the cylinder head to heater inlet connection. The manufacturer notes that it must be cut in two to install the heater valve; use the original hose to measure the approximate distance before trimming. Confirm routing and fitment against the vehicle before final installation.

Quality Assurance

URO 1378850 is made from durable EPDM material and carries a 24-month unlimited mileage warranty. Its molded OE-style shape and temperature resistance support consistent performance in demanding HVAC heater hose service.
