    Coolant Cross Over O-Rings

    If anyone needs o-rings for the coolant crossover I can supply 4 rings for 10$ (1 extra incase of a goof up). Thats alot better then 3 for 20$ + ship + tax from MMR. The quality is the same. Made of EPDM commercial grade rubber rated for water, steam and several other chemicals like Glycol (main coolant chemical). temp range from -70 F to 300F. I've got them on my Lincoln Aviator and have been doing just fine.

    Sorry if I'm being dense here ... but, between what pipes?

    I've taken off 3 Marauder crossover tubes now, and each time the crossover tube only had 2 O-rings on it.

    The crossover tube is 2 pieces joined in the middle with a double O ring seal.
    Each 'downleg' has a single O ring seal.

    The COT takes (4) O Rings total. 2 in the center of the pipe, one on each side that go into the heads. Just to make it clear for everyone.
