I got it started and started chasing leaks all but one were hose clamp retightening, but that one was fun to get to and do. It was the lower water neck on the water pump. I have one of those rotatable necks and I loosened it and rotated it but the t-stat moved and the gasket is attached to the t-stat and that leaked. So I had to drain the coolant and I fought it for about 30 minutes before I got it in place and used some right stuff also for extra sealing. The t-stat kept falling out as I was twisting myself into position to get the bolts started, which led to the Right Stuff getting all over my hands and arms a few times. Just all-out fun. Then the bleeding of the system started and I filled it and it got to 225* and I shut it down. Brought out the special LS fill funnel that allows you to fill the funnel to help bleed the system. So air bubbles are coming out and then the funnel fills up and is spilling coolant and so I get another funnel and jug to catch spilling coolant and then Mount St. Helens commencing and I have coolant spitting 1-3 feet into the air, so I bale out of the bed and shut it off. Yeah, I got sprayed with coolant, but not bad and it didn't burn, which I find interesting but I'll take it. Now in one of my iterations of let's run the steam line like this, I put in a 1/8" brass pipe extension with plug. So I uncork the plug and air escapes and that's good, but I'm wondering why the special LS funnel thing didn't work, but it may be because of the height and routing of the hose and length. Anyway I bleed it a couple of more times and I may have to bleed it more, but we shall see. The steam line runs into the water pump. OK, leaks fixed and bleeding the system is pretty much done,
Now why does only 1 fan come on?!!!!
Both trigger wires click the relays, but one fan won't come on. I have power thru the wire to where I connected it to the fan harness, when I test it with the battery and I switched the connectors on the fans to make sure it's not a dead fan or bad connector and it's not. One fan refuses to come on. There are 3 relays, 2 are 4-prong and one is 5-prong, so I swapped the two 4-prong relays and that's not it. So I cleaned up and went online and ordered new relays and fuses to make sure I do not have an issue with any of the relays(or as spares), and two 40amp fuses. I'll swap out the 5-prong to see if it's a relay or fuse issue, although I'm leaning that the 5-prong relay is the issue. I should get the 5 prong relay tomorrow, so stay tuned. The other stuff comes on Wednesday. I hope it's that one relay. It runs at 214* with one fan at the time I stopped working on the fan issue. This is 4-6 degrees hotter than I remember from when I had the radiator in the bed before. What I can't remember is if both fans worked then, but I'm pretty sure they did, so why only one works now is baffling as it was all in my garage this whole time. It will be interesting to see what the temp does when both fans work.
I still need an overflow, and although I said I was going to leave the other radiator in until I test this new setup and am happy, I'm not. I'm going to remove it and fight the new set-up even if I have to buy a Meziere electric pump or a bosch electric pump that I saw one guy talk about and take a water pump and pull the impeller out of. I should have the old water pump that I can check to see what it will take to do that.
I have to secure some hoses and put some anti-rub thru devices( known as cut up hose to wrap around the EPDM for extra protection) at some possible contact areas.
