Drilling thermostat

[tpunx99GSX]

Water actually cools much better than anti-freeze. Anti-freeze is basically to keep the coolant in your block from feezing durring the winter anc cracking your block and sheit. Pressure test the system, and go from there. and yes, jello shots FTMFT :)

I believe it also prevents rusting in the coolent runners.

Also make sure that both fans are running. I had this kind of problem when i was running only one fan. Managed to fit the other fan and it cooled right down.

So... anyone know where I can get a coolant system pressure tester thingamajig?

Just use a boost leak tester and attach it to your radiator hose, but be sure not to plug the other end of the hose.
LOL jk

Both fans were not running, hence the reason I put a new one in yesterday. Did not affect things much.

just stop up today and we will get it fixed

I'm pretty sure you can rent them from checker too

Did you adjust your coolant temp off-set in dsmlink? My car worked very well with the fluidyne radiator, 160 deg thermostat and water wetter. I ran 70%water, 30% anti-freeze. I adjusted my temp off-set to 20 deg so the fans would come on 20 deg sooner. Worked great. Just remember that a cooling system has a "window" of operation. The thermostat determines the low end, the fans and cooling efficiency of the system determines the high end.

You could try building a sheet metal air scoop under the radiator to direct cooler air twards the radiator. This way the radiator won't only be getting air thats been pre warmed by the IC and AC core

I dont think the 1g dsm link version has the coolant off-set. The fans on a 1g arnt controled by the ECU.

^^ Ahh Very nice idea! I think I will try that with the scraps I got laying around. Any clearance issues carltalon?

None of the Auto stores around here that I called, had a tester (napa, checker, auto zone). Mark had one so I went up there and we tested it. On the drive up there, the car was just fine. Probably because it's a cooler day today then it was yesterday. Anywho, we did the test and found one tiny little leak where the clamp wasn't holding real tight. So we replaced the small rubber line and used the screw type clamps so it'll hold and seal. Topped off the coolant, burped the system, and so far so good. But again, it was working good on the way there also because of the cooler day today. But we beat on the car a bit on the way home to see if we could get it to overheat, but it didn't. So we'll see how it works on a hotter day.

Also, I will be getting a vent for my hood to help some of that hot air escape out of there. I figure it can only help.

Well I took it on a little road trip to test it again since Mark's shop really wasn't that far away. After about 15 minutes, the temps climbed and the CEL came on. So I turned on the heater, CEL went away, and we drove probably another 45 minutes with the heater on and it worked fine. If we turned the heater off, the temps would climb again. I am going to be installing a vent in the hood, just over the exhaust manifold. Hopefully that will help to expel a lot of the heat in that area, and help out my situation a little. It'll look similar to this, but I'm only doing the big one in the center, not 2 of them like they did here http://carbontrix.com/images/inhood.JPG
