Hose kit?
So I've had the car for 3 days now... did a quick fix on a leaking hose (going into the throttle body), but really, if one is bad, the rest are probably not far away from leaking.
I looked the rest over carefully, some are bulging a bit near the clamps, some aren't. Should I replace all of them? Anything else I should replace while I'm doing this?
Car is a '93 40th Anniv. car, 100k miles, auto, and it runs great.
I can't find a single set of all the hoses I'll need, which means a) it's expensive buying them one by one and b) I'm not sure what to buy, there are a whole mess of 'em.
Is there a cross reference list somewhere of which hoses to buy? How should I go about this?
Thanks

If you are going to replace one it's well worth it to replace all of the coolant system hoses. Check EBay for these hose kits. They are usually silicone. Also try and find the good made in Sweden hose clamps with the blue plastic. These will never loosen up or back off. Don't reuse the factory hose clamps.

If you look at the hoses, there should be a date stamped in white on the hose that will tell you how old it is. I would replace all the hoses. Rockauto has a good price on them as singles.
Note: there are several hoses that are attached to metal lines with a pressed fitting. You can't get these anymore, but and make them up by cutting off the clamp. Check out my old post...

I see two options on ebay. This: http://www.ebay.com/itm/1993-1994-Co...Z_xSNQ&vxp=mtr
And this: http://www.ebay.com/itm/Mishimoto-Si...NXjwjO&vxp=mtr
This Mishimoto set doesn't look complete. How would I handle this? Would have to get all the other hoses separately.
The entire set (first link) looks tempting to buy.
Thanks

Thanks. What's different about the 1995 model? They dropped the routing through the throttle body?
It does get cold here in NJ. But I've never seen a heated throttle body before, and never had a problem with any of my other cars :-)

I'm born and raised in Jersey and have been a Vette owner for many years and have never seen a throttle body freeze. Enjoy your Vette and all the best.

I ordered the standard 1995 kit. Thanks for your help, all!
Now - what about the serpentine belt, and thermostat/water pump? If those all seem to be fine, should I leave them alone?
The car runs VERY cool when idling with the A/C on. When the car is stopped at a traffic light, the temp drops to what looks to me like "very low". probably about a quarter of the way up the scale.
So it seems all is working OK. I don't see any other leaks.

From who and what part #? COMPLETE is HOW COMPLETE? I don't know that I'd have "rushed" to this purchase.
Molded hoses that have conventional clamping properties are very few 5 - total I believe. The rest of the coolant hoses are purpose built using machine compressed short hoses and formed tube.
I believe if I were doing all I'd do the heater flow control valve also.

You should pretty much ignore the analog temp gauge and use the digital gauge. The digital gauge will be more accurate and will show temp changes faster than the analog gauge. When you say "very cool", what temp value does the digital gauge show? What is the coolant temperature when the engine is fully warmed up and cruising? Could be that a prior owner installed a thermostat with a lower temp opening.
C4's are designed to run at slightly higher coolant temps in order to reduce emissions. A "normal" coolant temp will be anywhere from 190 to 210.
