Genuine Mazda Small Coolant Lines KIT (4pc) – 1989-2005 Mazda Miata
Mazda Miata 89-05 (NA/NB)
Smaller Coolant Hose Kit
(4 hoses that route coolant from throttle body, oil cooler, back and front of head)
These hoses are often overlooked by most people. These hoses are the SAME AGE as your radiator hoses. These run the SAME COOLANT through them. If your radiator and or hoses are new and these aren’t, you might have to take care of them.
We see a lot of cars fail due to these hoses letting go. These small hoses route coolant from the back of the head to the oil cooler(if you have one), then from there to the throttle body, from there it goes to the thermostat housing and then from there to the side by the water pump.
EVERY YEAR CAR is different! 1990-1993 is one set of hoses, 1994-1997 is one set of hoses, 1999-2000 is one set of hoses, 2001-2005 is one set of hoses. If you have done a motor swap into your car, please verify before ordering.
*these hose kits will not work with a MSM/Turbo model.
