Default Project Mission: STAY COOL BABY!

So, in light of recent cooling system temperature issues, I have decided to embark on a mission to combat the heat being generated.


I know the standard scuttlebutt lays claim to these babies running hot...but I am just not a fan of the extra heat produced by an already hot running engine - especially since the before mentioned purpose is emissions related and emissions are not regulated where I live.
To add; the high desert heat has been a bit high this year.


My C5 has around 85K on the odo and since the previous owner is deceased (may he rest in love), I have absolutely NO CLUE what has or has not been done to this car either performance wise or preventative maintenance wise. That being said, even if what I am about to do is not really necessary, I can at least view it as preventative maintenance with higher quality products.




A little back-story.


My C5 came from California. I recently picked it up and drove back to New Mexico, this past fourth of July weekend. On my way back and about the time I hit Arizona, my temp gauge - which was running at about 190 the whole way, jumped up to the 230-245 range. I immediately stopped at a rest area and checked for debris in the radiator housing (nothing) and observed the coolant surge tank boiling...and leaking from the cap.


I cranked the AC and along with the night temps being lower (60s), I was able to maintain the temps around 220, until I arrived home in Santa Fe.


Since I returned, I have installed a new water pump, new thermostat and a new surge tank cap. Now, the temps do not go above 230, but it still gets to around 227 regardless of the outside temperature or distance driving. I am pretty sure the AC condenser and radiator are most likely caked with road grime and with the age of my 2004, along with the miles added - it probably has some baked hoses and the surge tank looks a little old.


All of that, plus my feeling that my baby runs a bit too hot, has led me to this mission.




The project will begin this weekend...*Stay tuned for more!

Good luck - hope things go well when you're working on the car.

...I am still waiting for a few parts to arrive. Sans any shipping issues, hopefully I will have everything to get started this weekend.


I will post photos and descriptions of everything I have acquired for this project, plus my opinions and reviews of the products.




Should be fun! Stay tuned!

I would like to see the results whenever you finish!

I used to worry about mine, but it will stay at a cool 196 unless its HOT HOT outside or I'm driving it really hard/in stop and go traffic

Since it seems to me that temps are controlled by a combination of the cooling capacity (in BTUs), thermostat, and fan switches, I'm curious where you're going? Saldana Racing has a fascinating pdf on cooling system operation. No idea if they make C5 radiators or not, but the information makes me really ponder if a DeWitt is in my future...

In for the results and products you use. I'll be changing all my stuff this fall when it cools off a little.

Not sure if these will fit our C5s but I recently put one (30102800 ) in my Eagle Talon TsiAWD. Holy cow! These move some air compared to the other fans I had. If I still had my 98 C5, I'd find a way to put two of these in. They will solve ANY hot issues.
The only downside is you have to upgrade the wiring (or run all new wiring like I did) as they take allot of amps compared to stock.

For a little more than the price of two of those fans (C5 has 2 fans) you can have the Dewitts Spal fan upgrade which is plug and play with no rewiring needed and no modifications to the factory shroud to attempt to mount the fans.

https://www.dewitts.com/collections/...products/sp015

These fans move over twice the CFM of air that the factory setup uses. Works with the factory radiator or many aftermarket radiators that use the factory style for mounting the shroud.

...Everything came in Today!
...Today is also my birthday!
...Tomorrow, I am free and clear to begin my work!


*I will lay everything I purchased for the project out in the morning, and provide details.


Interesting side note; we just moved into a new house and this will be my first car-related project in my new garage - Time to break it in!!!

Default Essentials for the mission...

Okay,


Here are all the items I purchased for Project: Stay Cool Baby...




The first is the cool it kit from SacCityCorvettes.


Even though I probably would not need it after the other changes...I figured it best to have as an emergency back-up and it only makes sense to add it while I am working on the cooling system.














I got the wired version...so I can put the little switch wherever I want!

Default Dewitts

















I picked-up a dual-core, all-aluminum radiator from Dewitts, plus the new fan assembly which claims double the CFM of air flow over stock.

Also purchased a silicone hose kit for the cooling system, and a new surge tank.
The old one was looking a bit brittle.


This new one came with a new cap as well

Default ...in addition...



Not specifically related to the project; I also decided to take car of throwing in new plugs and wires, along with an oil change.
...and some much needed wiper blades (been raining a lot here in the desert!

The low-profile jack just barely made it!

Default The tear-down...

Tearing it down...


I have no manuals for this car, and this is the first time working on a Corvette.


There are four 10mm bolts to remove in order to take off the radiator top cover. Two on each side.


Once I got mine off, I began to see all the junk stuck in my AC condenser and radiator.
