    First post but digging into some over due research to fix my partially blown head gasket. It's been bad since I went through Death Valley and it was 128 degrees out! Not cool. Literally. I just ordered the Ranger heater core and Tees suggested here and will install that as part of the rebuild.

    Anyway, it might be minor but won't adding the extra cooling effect the flow of coolant to the internal front heater core of the van? It seems like you are counting on the coolant flow being strong enough to circulate through both cores or maybe the front heat isn't that important to you, like here in San Francisco.

    Thanks so much for this amazing forum BTW!!

    I installed a shutoff valve (scavenged from a junkyard vehicle) and find it useful. I live in Utah where it gets cold in the winter. I want my engine to heat up quickly and my heater to blow as hot as possible when it's -10 degrees! I didn't install a remote cable though, usually I just crawl under the van to open the valve in the spring once freezing temperatures are over with and leave it open through the summer.

    That's a good point if you live where it gets extremely cold. It rarely gets below freezing where I live. If you live where it gets below zero then having a valve there could be beneficial. Tim

    Just wanted to share my experience with this process. I chose to go with the dorman y 5/8 47238hp. I think this will provide better flow than the standard T and create less turbulence in the cooling system. It also makes for a cleaner install or at least cleaner for my install skills. The hose can be held closer to the body and reduces the amount of any hanging hoses or kinks.
