    Coolant hose extension?

    Hey guys I'm looking for this plastic coolant hose extension that connects my expansion tank hose to the spider hose.

    Anyone know where to find it?

    Realoem.com? Just looked, are you sure it's not part of the expansion tank?

    Thanks for the replies guys. It's actually the little plastic piece that doesn't have a number between hoses 6 and 7. I've searched for hose extension, adapter, connector, etc and I'm coming up dry.

    Dorman makes a bunch of universal coolant hose connectors. You can usually find them at any of the mainline auto part stores. I don't recall the ID of those hoses but take the old connector to the store and you should be able to find a match.

    Thanks Twistytee, I ended up at home depot today, went to their plumbing section and although I didn't find the exact sizes I needed, I found out what they are called.. Barbs. I specifically needed one that converted my 3/4" #7 to a custom 7/8" #6 I have routed directly to the waterpump. I found one here in case anyone else it. I bypassed the heater core and throttle body lines so no need for the spider hose.

    Maybe it was part of the hose, put the part numbers into ECS's website. They've got the best pictures of parts. That way you can see which hose it's a part of.

    I replaced both of those hoses last fall and the plastic connector wasn't included with either part number. Mine was still in good shape so I re-used it, but it's a pretty generic piece so I'm sure the plumbing barb with hose clamps or a Dorman reducer connector from your FLAPS would serve the same purpose well enough.

    IDK how the PVC will hold up to hot coolant, brass would be better, find barbs that adapt to pipe thread and make a three piece fitting. Might be easier than trying to find a barb with the two sizes you need.
