Afco Radiator (current performance) and TB coolant lines
I am so close to starting and my last thing I have to do is to hook up throttle body coolant line to the radiator, but I just realized there is no place to hook it to the afco radiator. Am I going to have to fab up a pipe that allows me to hook up the TB coolant hose?
Once this is hooked up, I am cranking this turd up tonight. |

Re: Afco Radiator (current performance) and TB coolant lines
Unless you are really serious about running those coolant lines I wouldnt mess with it.......it just heats up the throttle air going into it when its at normal operating temp. A lot of people just bypass it.

Re: Afco Radiator (current performance) and TB coolant lines
Hes saying there is no place on the radiator to hook to. You need it, these engines get massive air pockets in the front of the heads.
On the dyno there is no place for that line either, so I have to bleed the crossover after I heat it up for a minute or so. Tons of air comes, its amazing... |

Re: Afco Radiator (current performance) and TB coolant lines
Just put a brass T in before going to the heater core

Re: Afco Radiator (current performance) and TB coolant lines
Or you could have an aluminum hose barb welded to your filler neck.

Re: Afco Radiator (current performance) and TB coolant lines
What we have done is take out the drain bung, and just put a hose barb in place of it on the bottom driver's side.
If you need to drain it, just pull out the barb. We have revised them and added in a spot for that under the upper hose on our latest shipment. |

Re: Afco Radiator (current performance) and TB coolant lines
i drilled and tapped a hole in my driverside tank right under my cap and put a hose barb in it. And in regards to what SweetS10V8 said about air pockets...its true. My radiator cap is on the driver side and when you take my cap off you can see all the bubbly water coming out of the hose from the crossover.

Re: Afco Radiator (current performance) and TB coolant lines
Ok what I did was use some thin pipe the size of the bottom hose and welded a fitting on. Works great. Just started it for the first time after fixing the solenoid stickin. Water seems to be flowing with no problems.
Thanks guys. |

Re: Afco Radiator (current performance) and TB coolant lines
The LS2 DBW and Truck DBW TB don't have fitting for the line to go straight from the coolant crossover to the TB. I've read of guys just tapping their waterpumps and running a line to it. But I don't want to tap my waterpump so it would be alright to just have the hose go from the coolant crossover straight to the "new" barb fitting on the radiator...Right?

Re: Afco Radiator (current performance) and TB coolant lines
Ok update...
I guess things are not ok. When I take my cap off, it bubbles so violently that it will shoot gulps/bubbles of water all the way to the headers. If I put the cap back on, it shoots that water into the overfill tank which of course gets full and purges. This causing all my water to eventually leave the system after a few drives. I also think there is a leak in the afco radiator now. I looked at all the hoses and cannot see leaks, but fluid looks like it is coming out of one of the welds on the bottom of the radiator. I am going to move the TB line to the drain valve like Jared said and see if it helps. |

Re: Afco Radiator (current performance) and TB coolant lines
Sounds like you're either pushing compression or exhaust fumes into your cooling system by the details you gave. I'd do a leakdown test also.

I agree with ^.
You need to do some diagnostics |

Re: Afco Radiator (current performance) and TB coolant lines
well I did a compression test ...
1) 175 2) 175 3) 174 4) 179 <- this is the cylinder where I modified the header to keep from hitting the steering column. Makes some exhaust noise there also (like a lawn mower) 5) 166 6) 220 <-wow wtf? 7) 171 8) 176 Number 6 scares the shit out of me, but according to the manual that indicates carbon build up. I am so freaking confused right now. All cylinders built up pressure on the first crank. |

Re: Afco Radiator (current performance) and TB coolant lines
Also to note..
1) No coolant coming out of exhaust. 2) No oil in coolant 3) No coolant in oil. I think I am going to move the TB bleeder hose again. Move it to the heater hose with a T. I just should have done this in the first place. someone else had the same problem as me and fixed it by doing this. http://www.ls1tech.com/forums/genera...out-210-a.html Do you guys think I should just fix the leak in the radiator by welding the leak or just send it back to Jared?

Re: Afco Radiator (current performance) and TB coolant lines
Update:
Long story short: The radiator was leaking. The truck now runs at 195 and the fans barely kick on. The reason I did not think it was leaking is because the overflow tank was dumping water so I assumed that is where the water was coming from. Jared replaced the radiator even though I damaged it taking it out (I accidentally poked some fins and damaged a tube). He trusted my story about how it was leaking months prior to taking it out. This swap has been the worst experience I have ever had with my truck. My computer was programmed wrong three times, radiator leaking, alternator relocation bracket squeals, and speedometer still does not work. Having said that, I would still do it all over again. The truck is crazy ass fast and is fun as hell!!! Thanks for all your help guys. |

Re: Afco Radiator (current performance) and TB coolant lines
I noticed my cooling system was loosing coolant about a week ago. upon further inspection, it's the radiator. --- seems to be losing it from the top on both sides where the mounting points are I think.

Re: Afco Radiator (current performance) and TB coolant lines
I took it out and had it pressure tested. When it was submerged into the test tank, you could see bubbles coming from both sides at the top of the radiator headers. You need to let Jared know because I think Afco had a bad batch of radiators. It wouldn't even hold 2lbs of pressure. It is only going to get worse. Be really careful taking it out because Afco will shit a brick if they see any damage to the fins. They will try to say that you caused the leak. Take pictures. |

Re: Afco Radiator (current performance) and TB coolant lines
Does it appear to be from where the actual pieces are welded to the top of the tanks, or somewhere else?

Re: Afco Radiator (current performance) and TB coolant lines
I can't really tell without taking it out. When it gets up to temp, I get a little steam from both sides at the top.

Re: Afco Radiator (current performance) and TB coolant lines
make sure there are some kinda of rubber mounts used when installing the radiator
AL radiators does not take vibrations too well |
