All coolant hose part numbers

The FD's are getting old and the rubber coolant hoses are often overlooked. As high as the underhood temps of these cars are all hoses should be replaced.

Here are all the Mazda part numbers for every coolant hose:

radiator hoses:
N3A1-15-185A lower radiator hose
N3A1-15-186 upper radiator hose

turbo coolant hoses:
N3A1-13-536 turbo coolant hose #1
N3A1-13-54X turbo coolant hose #2

AST hoses:
N3A1-15-380C AST to overflow bottle
N3A1-15-184A AST to radiator
N3A1-15-183 AST to coolant neck

throttle body hoses:
N3A1-13-681A upper throttle body
N3A1-13-691B lower throttle body
N3a1-13-692A water pump housing to hard line (behind alternator)

heater hoses:
FD01-61-213B block to firewall hard line (driver side)
FD01-61-212A heater core at firewall
FD01-61-214A water pump housing to hardline (passenger side)
FD01-61-211A hardline to heater core (passenger side)

If you go to Mazdatrix.com, you can price the list on these. Then reduce it by about 15-20% if you call Ray at Malloy.

Damon, thanks for giving out that info!

So far I have paid:

$18 for the upper turbo hose
$28 for the heater hard line to the pump housing
$11 for the lower turbo hose
$07 for the lower UIM hose

BTW, the lower turbo hose is a PITA to get to. It is very hard to get the lower turbo hose clamp off; especially when the engine assembler left the tangs of the clamp at a 05:35 attitude.

Has anyone replaced the spring clamp with a screw type?

Check the Ray Crowe/Malloy Mazda thread on coolant hoses right now. IIRC he is selling all 14 for $140, which if you do the math averages out to $10/ea.

If you call Malloy and tell them you want all the hoses then you will not need to recite all those part numbers.

thanks Damon.

i remember driving my 80,000 mile 1st gen on the expressway and smelling just a whiff of coolant. i immediately switched off the ignition. it was a rupture in the driver's side coolant line from the heater/firewall to the block just below the oil filter.

the engine vibrates, the firewall connection doesn't...... creating lots of challenges for that specific hose.

the two coolant hoses absorbing all these vibrations are the driver's side firewall to just below the oil filter and the front coolant hose from the hardpipe ( runs alongside the motor )to the front of the motor on the passenger side.

mix in our underhood temperatures and the fact that the rotary is prone to immediate failure from coolant loss, unlike a piston engine, and you should have significant motivation to call Ray.

either buy some new coolant hoses or a motor.

Sage advice. Not too long after buying my FD I ruptured a turbo coolant hose. What made me mad was that I swore for a few days previous I could smell whisps of coolant after shutting the car down but could locate no leaks and was losing no coolant. Once the hose ruptured t was obvious and I was lucky to be close to home.

Back then I didn't know where all the hoses were. Starting over again I would have replaced them all the first week or two I had the car.

The 14 hoses for $140 is about as low as he can go, prolly right above cost.

For me its worth replacing them all at the same time. That way I know exactly how old every one is.

yes, the 2nd turbo hose is a PITA!! i have screw type on both, they came loose after 70,000 so it is something to be retightend every 50k i would assume. they were leaking on the turbos.. just enough to loose coolant but never see any on the ground, i hope this solves my over flow problem.

Does anyone know what type exactly these rubber coolant hoses are made of?

Cause i think it would be cheaper and make more sense in the longrun to go to like an autozone and getting a roll and just cutting to your desired length.

Also have any of you used silicone hose instead of rubber hose for coolant?

SARD sells a roll for coolant, wondering if thats any good.

The main issue is that the OEM hoses are pre-formed. You can use standard "heater hose" from NAPA or Autozone, but you'll end up getting kinks in the lines to make the required bends. You can also get pre-formed heater hoses made for other cars and cut them up for your own use. However, that will end up being just as expensive and more time consuming than just getting the OEM hoses.

Just a wild guess here but maybe someone in the FC section?

Look through the FAQ and stickies in there. I remember there being a parts diagram in there somewhere so you can get your own part numbers if needed.

There is a thread about how silicone hoses have a high water permeation rate and cause loss of water in your cooling system..
