Water pump...
Well, that elusive coolant smell has finally be tracked down. Had it up on the rack for an oil change and I could see a little bit of antifreeze on the cross member.... Looks like the water pump is leaking a little bit...
$234.00 sound about right for an OEM pump on a 95?
I guess this would be a good time to change out the thermostat to a lower temp. What's the best way to go?
Once I get the T-Stat changed, I can get a dealer to change the fan settings, right?

Re: Water pump... (joecaver)
On the LT1, they improved it so much the pump cost $200 and the distributor costs $300!
If your pump has been leaking, you might want to go to the next step and remove the opti, split it open and see if it's clean. The opti on the 95 has much better seals and the vent lines to keep it dry, so I guess it's a toss-up whether to do it. It only adds another 1 - 1 1/2 to the job. If it were mine, I would do it, just for peace of mind.

I checked around and the average price seems to be about $200 for the pump.
Is there a higher-performace pump available? I noticed that there are for the earlier C4's...
What temp t-stat is best? The stock is a 195, I think, so drop to what? 180? 160?

To answer the question...

I've had great results from the Edelbrock hi-perf water pump.
Flows about 25% more fluid. Look at Jeg's or some other catalog.
Good luck!

You can install an electric water pump. It dropped my temps 8-10 degrees in regular driving, at 115MPH with ambient at ~80 degrees in the desert the temps never went above 218.

Arisa suggested an Electric. Anyone have any experience with ELectric Water pumps?
Hey John, I see you posted while I was posting. What brand electric did you get and where?

Re: Water pump... (Preacher)
I have a Meziere, I can't say enough about the company or the quality of their product. I'd do it again in a heartbeat.
I bought the HD pump from SpeedDemon (CF supporting vendor), but I've heard that internetracerssupply's price is $20-30 cheaper. It goes for about $200-$230. You'll have another $15-$20 of electrical to add to it.
