They have a lot more coverage, plus the extra power you should have plenty of cooling. Nice find.

Andrew, What year Volt are these from. Im using a windstar fan. It works but is old school and has high amp draw. Would like to swap to something like this later. How were you planning on tying in to get the ac to control speed?

[ryeguy2006a]

Wow, you aren't kidding. Those fans look like they belong with that radiator.

This one is from a 2015 Volt, but I think the range is 2011-2015.

I plan on installing a AC pressure sensor in my AC system, which will allow me to use it as a variable to determine fan speed.

I love that you’ve found an OE solution that’s affordable and does exactly what you need. You’ve got me thinking of trying something similar.

I’m curious, will you tie the signal wires together so that both fans are working in unison, driven off of a single Terminator output?

Yes. I am going to use a single output to drive both fans. With variable speed fan control, there is not need to run the fans separately.

Thanks for the input, guys, and sorry to derail the conversation. Back to the build!

Andrew , whos or what car did the windshield wiper motor come from , does it park the wipers ? im assuming it has delay as well . certainly looks like a modern motor

That's a DSE kit from 20 years ago, without a park feature.

thats what i was guessing and afraid of lol. Thanks

The weather was really nice this weekend, so I decided to mess around with the engine a little bit. Popped the valve covers off just to do a visual inspection. Everything looked really good.







Pulled the spark plugs and they all look like this. Also pretty good.



The counter sunk bolts that hold the engine mount adapter plates to the engine are going to be a problem. I got one loose, but the rest are stuck pretty good. I broke one 3/8" drive 6mm allen wrench in the process.

I am soaking them with some PB Blaster, so I hope that does the trick. If not, might have to add some heat.

Nice update Andrew!
When you get them out, before reassembling put some anti seize on the threads of the bolts but not on the cone/ counter sunk part of the bolt . That will help next time you need to remove them.
If you can’t get them to come out because the Allen rounds out you can weld a nut to the head of the bolt and use a socket.
Keep the updates coming!

I actually did use anti seize on the threads but not on the cone. I'm thinking there is a little rust in the cone area.

[David Sloan]

Gotcha! The cone is the very reason these type of bolts hold so well with out coming loose. It’s a love / hate relationship.��

I've found flathead capscrews can be difficult. If there is room I typically hit the sticky ones with a flat ended punch. It usually shocks them enough to get them loose.

Jeff,

Thanks for the tip. I actually just tried one of those manual impact drivers, without much luck. Might be time for some heat.

[andrewb70]

Still haven't gotten the bolts out, but haven't really tried. Today was super busy with having to juggle four tuning customers, but I did did get a few more parts.

I have mentioned it before, but part of the goal is to get the AC system fully functioning. It is an older VA Super Gen II system, but I see no reason why it can't work as it should. Another thing that I want to do is fully integrate the AC system with the Holley ECU. Today I received some of the parts to do that.

This is a new drier that I got from BP Automotive. What makes it unique is that it has both a binary switch for the compressor and it has a GM pressure sensor.





The binary switch will work as a safety for the compressor. The AC pressure switch will be an input to the Terminator X and will allow me to integrate AC as part of the cooling fan control.



I also picked up these pressure sensor connectors from EFI Connection. These connectors are pretty standard for GM and aftermarket 5v pressure transducers. What makes these a little unique is the little lip that is molded at the end of the connector. I plan to modify a lot of the Holley EFI harness and part of the modification will be sealing off the sections of harness for the pressure sensors. These sections of harness will be encapsulated in Raychem Dr25 heat shrink tubing and the connectors will have heat shrink boots on them.

It looks like a nice setup.

[David Sloan]

Sweet thanks for sharing! I plan on using your build as I get to that point with the Elcamino. I’m sure when I get closer to that part of the build we will be taking more as you will get to tuning on it.

I really like what's going on here...
