Dayco 71448 coolant bypass hose for the 1987-1999 Toyota Tercel and other vehicles connects the pipe to the thermostat and water pump.
A hose that is cracked, swollen or soft, or that seeps coolant at its ends, can let coolant escape and lead to overheating. A leaking thermostat housing or water pump, or a loose clamp, can cause those signs too, so find the cause before buying. The engine takes one, at the pipe-to-thermostat and water pump connection.
This hose is a direct-fit replacement for the 1987-1999 Toyota Tercel and the 1994-1998 Toyota Paseo. The 1987-1988 Toyota Tercel is listed with the L4-1.5L engine.
