    Disecting coolant hoses p/n

    Since I'm tearing the car apart, I figure I might as well replace my coolant hoses while I'm at it.

    I've decided I want to get the aftermarket, thicker, cooler looking ones for the 6 main hoses.. and then get the smaller OEM hoses.

    Question is - can someone tell me which P/N I need to remove from this list?

    Re: Disecting coolant hoses p/n

    What is the reasonable price and hours it'll take to replace all the coolant hoses? Assuming I am getting the hoses myself.

    Thx

    Just recieved my hoses from Tim, @ honda acura world 2 weeks ago. Great pricing. A local nsx mechanic qouted me $800 for thermostat and hose replacement. I feel that is high, my friend is actually doing the job next weekend. Frank

    $800 is for labor only?

    How much are the complete set of hoses?

    $800 was labor only. I paid $311.84. This price includes all 23 hoses+ a oem thermostat. Shipping was free.

    Re: Disecting coolant hoses p/n

    Finishing up collant hoses this weekend. Only have the mibble 3 left, then add the anti-freeze, and bleed the system. Actually, this job didn't take that long. So far took my mechanic 3-4 hours so far, and he wiped everything down and had me standing close by to make sure the new paint job didn't get damaged.Frank

    Hi guys,

    i've done this recently, so i leave here all the Info about this "Hose Job"

    I used a kit for the "Big 6" hoses from VENAIR and all the other ones, 16 of them, were OEM.

    Hose Scheme from the Honda Online Catalogue:

    Oil Cooler

    Radiator Hose

    Water Valve


    All Hoses above, one by one:

    Hose 01 Hose 02 Hose 03 Hose 04

    Hose 05 Hose 06 Hose 07 Hose 08

    Hose 09 Hose 10 Hose 11 Hose 12

    Hose 13 Hose 14 Hose 15 Hose 16



    All Hoses, 16 OEM and 6 Silicone (VENAIR):

    OEM Silicone

    Hope that this helps to clear all doubts

    Thanks,
    Nuno

    first of all, thanks very much.... but man... with those kind of compliments, i may drown in my own drool

    i really like to document everything i do the best i can, but sometimes the ich to install things is so intense, that i forgot to photo and when i realize, it's all already installed ...

    Thanks once again,
