Hey pfilean,
I don't really have too much more to add on the waterpump front. Yep, I put the 58-594 in and finally took her out for a spin last weekend. Everything looks good so far, but yes, it's fall/winter and outside temps are in a sweet 40-60 degree range around here these days. I have a 160 degree thermostat and the car is averaging right around 160 - 180 degrees. That's where I'd love to see my gauge on a hot, 90 degree day, but will have to hold off until next year, that is unless it really IS the end of the world come Dec 21st! lol
I will say I was impressed with the quality of the Cardone pump. Looked and felt good holding it. It's got the same impeller as that junkyard one I took a pic of, so I'd say it's a real life actual Pontiac pump and not some Frankensteined together pump like some of the others in the thread. Can't really say if it's better than those ones with the propeller looking vanes either. we'll just have to see what this coming car season's going to bring us.
I'm hoping this will do the trick as I've gone through my cooling system so many times now, and tried just about every trick out there. I've got the shroud, sealed off all the gaps between the radiator and core support. I've had an aluminum radiator, but now have my original in there, but it's been re-cored, so it's like new. The motor was fresh back in 2008 and I've done what I can to take care and keep it clean inside and out. I've tried that water wetter stuff, but recently found it doesn't really do much if you're using coolant. It's supposed to go into cars running only water. Loses it's effectiveness when mixed with antifreeze.
My system is clean, fresh coolant, new thermostat, and this new pump. Life is good now. I'm fine going down the road. My trouble hs been similar to you...Pull up to a light or get stuck in traffic and watch that temp climb. Funny thing is, I swapped intakes last summer. My last intake was an Offenhouser and I had heat issues with it too, but had 'em solved until I made the swap to a factory Pontiac 2X4 intake. Things were fine at ffirst, but as summer rolled on, the gauge started rising too.
I'm gonna keep hammering this. Almost considering an electric fan, but I think the darn car should work as it was built with no aftermarket stuff. My tune is good also. If this was an advance issue, the consensus is the car would be overheating going down the road. That doesn't seem to be the case, but I'd like to learn and play more with it if for nothing else, more experience. It MIGHT help. Couldn't hurt.
well that's the story so far until next summer and I'm sticking to it!
I'd say, the 58-594 is THE pump that should be in our old cars. I sure hope Cardone has gotten better these days than your past experience. Time will tell!
