I am interested in all the replacements. Who sells a complete kit or maybe a silicone hose coolent hose kit? Thanks

You can get silicone reinforced radiator hoses, but not the other hoses. (They need to be formed to the correct shape, so generic silicone coolant hose won't work).

Like DaveW said, Malloy will sell you the whole kit for a good price, AND get the correct parts (unlike many dealers)

try SAMCO main hose kit, # TCS23/C ~$130 and Mazda for all the secondary hoses.

you can get that corrogated stainless steel hose and do the bends yourself ~130 at any performance store, and the kit should be about enough for the radiator and heater hoses. bling too

The Mazda hoses are just a good idea. They have been updated over time to a better grade of rubber that deal with the heat better. Not to mention they fit perfectly and work right.

I really can't see justifying the expense of the silicone radiator hoses. The radiator hoses are typically the most durable of all the hoses in the system - you can buy new Mazda hoses many times over for the price of the silicone hoses, and the Mazda hoses will easily get you 150,000 miles of service. The only reason I can see for the silicone is for blingin' up the engine bay a bit - nothing wrong with that, but I wouldn't get them as an upgrade.

also, you might want to use the stock C hose clamps. using the worm gear type hose clamps can often cause you to overtighten the clamp and leads to the hose splitting.

Ditto. Not to mention the stock spring clamps are constant torque - as the cooling system expands and contracts, they always provide the same pressure on the joint.

When you say Mazda hoses do you mean rubber hoses?

There is nothing wrong with the OEM hoses, you are wasting your money on anything else. I'm replacing all of my coolant hoses during my engine rebuild, but they are all original at 10-years old/85k miles. I did replace my upper and lower radiator hose 1-1/2 years ago when I replaced my radiator but I don't recall there being anything wrong with the old hoses.

Mazda OEM hoses = cheap, pre-formed, and they work
Samco = pre-formed radiator only, they work, and you have to sell your first-born

I just got a complete hose kit from Ray at Malloy for something like $145 for all 14 coolant hoses. It's a good deal, and the hoses are very good quality with all of the correct bends built in.

My original 13yr old, 62K mile hoses were in surprisingly decent shape. The turbo coolant lines were the only ones with substantial wear (pretty crispy due to all of the heat). I just couldn't see on skimping for $100 on a cooling system as "delicate" as the FD's where one little hiccup can lead to a many thousand dollar rebuild.

Be prepared for some bruised knuckles. It seems that the factory faced all of the clips on the band clamps in the most difficult position to get access to. It probably took me a total of 6hrs to change all of the hoses on a partially disassembled engine bay.

I got a set on ebay for $45, the are reinforced silicone. The brand is OBX, im not very fond of the brand, but i gave them a try. i cant really say if it was a perfect fit for stock, because i cut them for the Greddy FMIC install.

So far so good though.
