What are you running for coolant? Glycol mix or straight water or water wetter and water?

Hi Vince!

I'm running a 50/50 mix of Oreilly's version of GM Dex-cool.

I have a second PCM off getting reprogrammed at the moment and he's going to turn down the fan on temperature as well as fix the programming for the AC and the reverse lockout. I also talked to him about this issue.

It may be because I'm not using (as of yet) a coolant overflow/recovery tank and it's sucking air back into the system. I guess I'm not sure how the more modern caps/radiators/vehicles are technically "supposed" to work as the stuff I worked on before was mostly designed to spew on the ground.

I'm going to get a cheapo reservoir from the auto parts store tonight to test the theory out and if it works, will be going to something a little nicer for a permanent solution.

yep, you will run low eventually,

I like this tank and run it on everything. Tucks in next to the battery.

That was my concern regarding cooling when I first ran the engine (LM7). I reprogrammed the fan controller to have the fan come on at 190* (I think the thermostat is 185*). Engine stayed constantly at 195*.

Vince, what is the proper cap to go with that jar? Since nothing comes with anything anymore, I'm assuming it's not included if I order the jar.


So, you had the same symptoms or did you reprogram it before you ever started it up? I actually forgot to ask what my PCM guy was going to reprogram it to....haha. He did express concerns about programming it to a temperature that is too low but I didn't ask him where the "cut-off" was.

any GM spin on cap from 1975-2000 will work. Still available at GM under pn 15630112. Also Oreilly's or Pep boys from Dorman Help. about 4 bucks

Actually the fans came on before the thermostat open. I have a stand alone fan controller (Dakota Digital), and it was programmed for the old Pontiac engine (fan came on at 185*). I reprogramed the controller to have it come on at 195*.

I ordered the Nova reservoir. Hopefully I'll have it tomorrow or Saturday since it's coming from Illinois via "speedy delivery" but we'll see.

Vince, was there anything special about mounting this part in a Camaro?

Thanks!

Just one screw through the inner fender brace. Most cars already have the hole there. The base of the tank just sits on the inner fender well flat. Theres a decent picture in that link I posted earlier.

I looked at the picture but I must be getting old. It was a little too small for me to make out the detail. I do think that I already have a hole there. I noticed it last night when I was installing the hood.

Speaking of which, UPDATE; I installed the hood last night! She's getting close!
