temperature gauge dropping

[SilverOne]

lately I've noticed that my temperature drops all the way to the bottom of the gauge at highway speed (2nd bar). Once I idle for a few minutes, then it goes back to the middle of the gauge. If i really push the car, the temp gauge will stay at the first bar.

is there something wrong? I thought temp gauge should stay fairly constant around the middle.

Sounds to me like you're low on coolant. Wait overnight until the car is totally cold, and open the radiator. Make sure it's full, and then fill the overflow tank to the full mark.

If everything looks fine, check your thermostat, maybe it's stuck...just replace it since it's cheap. If all else fails...it's possible you have a bad waterpump :-/

I'd check the thermostat first which is suppose to keep your temperature level at all times..good luck..

I agree. It sounds like the thermostat is stuck open.

I had the EXACT same problem with my '96 a year ago. Simply replace your thermostat for a quick and easy fix. $170 for the parts, but I'm sure you can get it cheaper (I didn't bother shopping around).

The problem is that the thermostat stays stuck open.

talked to mechanic, i was told that one needs to bleed the entire cooling system in order to replace the thermostat, takes about 4 hours, is this true?

what is average time/labor for replacing the thermostat?

I'll post the labor costs when I get home from work today and take a look at the service receipts.

SilverOne,

I would have to say your dealer is a little too rich for me!!!!!!!!! I would say 2-2.5 tops. The thermostat should be about at hour, since you have to drain the coolant, which will take loosening a few drain plugs and watching!

The bleed process is about 1/2 hour - 1 hour total. I have done it personally in 20 minutes, a quick drive to warm it up, then topped if off with a final quart.

BTW, I just spoke to Tim at www.hondacuraworld.com and the thermostat and gasket is under $25. So 2 hours labor @ $70 + $25 = $165. (I also would add about $20 for coolant, 2 gal. @$10, It takes 12.3 quarts 50/50 mix, so you will need two gallons of Honda coolant, so let's say $185 MAX)

Sounds very close to the cost from Soulstice!!

(If the labor rate is $65/hr it would be even closer with Soulstice's quote)

Frankly, if it will take the tech 4 hours, I would be concerned about his NSX experience level.

HTH,
