What temp Thermostat does a 2002 Blazer have?

[MikeMike]

just wondering, GF's blazer was running at 210 today which seems high compared to what i remember

produced the answer 195.

Looks like a 195 stat according to O'Reilly.

Edit: Too slow.

thats what i thought it was.

so 210 means something is up.

she says her coolant fluid is either gone or really low.

if it was gone, i figure it would be hotter than 210, but with a lil in there i figure it should keep it around there.

As a lifelong shadetree mechanic, let me assure you that for a 195 degree thermostat, 210 degrees is the "normal" operating temperature.
Keep it topped off with coolant and keep an eye on it, should it start to rise considerably over 210 degrees, I would have it checked out.

In these newer vehicles, with the DexCool coolant, it is a good idea to add a "cooling system sealant" (stop leak) to your coolant.

The DexCool is acid based, meaning it dissolves any impurities in the system, keeping them from clogging the radiator and/or heater core.

These impurities are usually helpful in the older cars as they tend to migrate toward small, pinhole type leaks and casting deficiencies in the block, thereby sealing themselves.
With the acid based coolant, there are no impurities circulating in the system, and any tiny pinhole is subject to loosing coolant.

The best supplement (GM recommended) sealant is available at Wal-Mart, it is Bars-Leaks Golden, it is a powder in a small tube. All organic, so it will not stop up any circulatory system components. Adding 2 tubes directly into the upper radiator hose will be sufficient. Never use ANY metallic or metal based "Stop Leak".

I added this to my Caddy when I did the engine swap, it barely loses any coolant, while my newer Silverado needs a 1/2 quart every 3 months or so (I've yet to add the supplement).

depending on what year your silverado is the intake manifold gaskets are very common that they leak coolant.
