Cooling ideas for V8 305 TPI 5.0 FI

That is my engine and I'm looking into upgrading parts to keep it cooler then normal. I bought a 170 thermostat and just curious for other ideas and other products I can buy to help in my quest for a very literally cool engine.

Like electric water pumps and cooling liquids etc..

Please don't just read and move on please give any tips and ideas or links that may help.

Thanks

 

I guess the question is why do you want such a cool running engine?

 

I bought the car so I can make it better than stock. It has been abused and anything to turn back the clock or add some life on the engine would be great. I just liek working withm y hands and looking forward to toy with the engine in small but effective ways.

 

I hear ya on that one buddy!
But I think getting it running cooler is not going in the right direction for ya, old carb'd motors, maybe, but thiese FI motors like this don't benefit at all from running cooler (despite all the reasoning you can throw at it). They run best at stock temp, just as GM designed them for.
PS - The computer kicks on the electric fans at a determined temp, changing t-stat and coolants won't help you in the slightest until you change that temp for the fan to kick on. I still don't think its a great idea, but thats how you can accomplish your goals.

If you want to work with your hands, and get that car running even better, there's a schwack of things to do that'll give more bang for the $$.... Headers, SFC's, etc etc etc!

 

Throw a tranny cooler on it and keep your tranny cool. Want to do some work to it, give the old girl a tune-up. -Nick.

 

Great guys thanks. The previous owner shorted the fan to a hot wire so its always on with the ignition. I'm going to rewire it back to stock relying on the computer and sensors. But i'm also going to put in a switch to the fan in my dash just for fun but for more control over the fan incase I want it on sooner.

The transmission lines already go into the radiator because its an automatic.

Are you referring to a different kind of tranny cooler or thought I had a 5-speed?

tune up is a good idea. Im doign research on how much I can do myself or with friends who know stuff. I hate paying a mechanic labor. haha

 

I think he means and aftermarket transmission cooler. The stock cooler doesn't do much, aftermarket ones are essentially mini radiators and are much more effective.

 

When thirdgens are at stop and go traffic, they will heat up due to no air getting to the radiator. All of the air is brought up by the air dam.

You want to be sure the engine gets up to a proper operating temperature, to ensure the oil is warm enough so it has the ability to lubricate properly.

With the fan switch and a lower temp t-stat, you should be find for cooling.

The fan switch is a simple mod. The green/wht wire on relay gets grounded by ECM. If you have dual fan setup only one fan is turned on by ECM, and at about 220. I used to have an extra foglamp switch in my GTA dash for turning on the ECM controlled fan. Had a illuminated fan logo and everything. It was so trick for 1998. He he

It is easy enough to simply add an extra wire to the green and run it through a switch to your ground of choice. This way, it will turn on by ECM when open, and close by ECM when closed/on. No, ECM wont mind if you ground it yourself. (I got some funny looks at a car club meeting) LOL

Yes, I have done this myself.

Your car goes into closed loop (reads all sensors) at about 190-200. Unless you alter ECM chip, it will run a lil rich on tabled default values, which is harmless enough. Although your combustion chambers wll be more sooty than usual.
