Chevy as most GM cars usually needs Dex-cool antefreeze
But Peak is OK as it can be used to top-off any color of automotive antifreeze including green, yellow, orange, fuschia, blue and red

Also check the system for leaks. If you need to add coolant at least once a month there is a leak.
Good Luck

Overheating gage when stop & go -2004 chevy tahoe


natural for engine temp to rise in Traffic - Until Themostat opens ) cooling fan sensor kicks on fan . But Antifreeze is not just a Cold weather item . Coolant is Absolutely Necessary for Hot Days . You must be full to recovery bottle setting of cold when checked prior to start up . Coolant for your make / model is Reddish - Pink colour and should have a reading of -25 thats negative 25 degrees the Lower the Better even - 50 .. Why ?? - 50 is 50 %% antifreeze / Coolant Concentrate MIX Gives Hot weather cooling Ability or very cold weather starting / winter HEAT .

I have a 02 Chevy tahoe....it sounds like coolant rushing throughout the engine while sitting at an idle and about every 2 or 3 days I gotta add coolant its not much also the low coolant light comes on...


I would perform a coolant pressure test because these engines are known for leaking intake manifold gaskets.Check and see if your oil is starting to turn a creamy tan color.

A light come on with a box with arrow pointing down looks like waves what does it mean


This indicates a low level of coolant in the coolant bottle/resevoir..... this symbol represents the radiator or coolant system liquid level.

Warning comes on to warn of coolant level too low.

When the engine is cold...remove the cap and check level. Add 50/50 antifreeze/water to level indicated on the side of the coolant bottle or tank.

Reservoir Bottles/tanks are usually transparent and you can see the coolant level through the plastic.

When coolant topped off to correct level, lamp will go out automaticly...no need for scanner or shop to turn it off. It will come on as a 'self check' when you turn on the ignition and if level is okay will go out when engine starts.

I have a 1997 chevy lumina what kind of antifreeze should i use?


The dealer recommend GM Dex Cool Antifreeze.
But there are complaint against this type of coolant.
http://www.stevesnovasite.com/forums/archive/index.php/t-128547.html
In GM cars we replace Dex Cool with Prestone green coolant.
It's up to you. Ask before but if you decide to change the type of coolant then:
If your intention is to add coolant only, then you need:
Mix with
ANY COLOR ANTIFREEZE
ALL MAKES ALL MODELS
of cars and light trucks
add to ANY color antifreeze
PRESTONE
50/50
PREDILUTED ANTIFREEZE/COOLANT
EXTENDED LIFE up to 150000/mile 5 year protection.
DO NOT ADD WATER.

If your intention is to flush the RADIATOR (Cooling System), then you need:
Mix with
ANY COLOR ANTIFREEZE
ALL MAKES ALL MODELS
of cars and light trucks
add to ANY color antifrezze
PRESTONE
EXTENDED LIFE up to 150000/mile 5 year protection.
On the back you have to read directions:
Step 1 Drain. Step 2 Flush. Step 3 Fill.
Recommended to ad 30% to 50% volume, distilled water. If you flush the system and rinse with water you must add only 30% water to the antifreeze. There is more water trapped inside the engine compartment, because the thermostat is closed. Make sure to have a coolant density tester. When you finish one of 5 balls must sink, that indicates that you reached 50/50 strength. That means 50% Prestone and 50% Water, which will provide to your car a -34F degree FREEZE-UP Protection , and +265F degree BOILOVER protection.The next day,with a cooled engine open radiator cap, and test the strength of coolant. If not quite right, then siphon coolant from the radiator and add antifreeze, or distilled water as necessary.
Make sure to disposal the used coolant properly.

Air conditioning works but not heat. blows out


At the radiator, drain and then flush with water then add 1 gallon of new antifreeze and top off with cool water. Now the cooling system will work.
If you have not performed routine maintenance on your cooling system - it will clog the heater in 10 years or less. Sometimes a bottle of radiator flush (purchased at any walmart or kmart) can clear the heater core - but you will have to run it with the heater on full heat setting for a few hours of driving.

I keep having to refill my coolant tank what do i need to do


There is a small hole under the extension behind where the pulley is mounted, most times barely visible. If you see any coolant there the pump seal is leaking. Many times it will show up better with the cap off, as internal pressure can sometimes push the seal against the shaft and temporarily stop the leak. If any coolant is found there,(sometimes it will run down the lower hose and appear like a bad hose or clamp) the pump needs to be changed. No, it is in no way related to a manifold gasket leak.

Check Engine light came on....


Coolant=Antifreeze. It's the same stuff. It lowers your freezing point and raises your boiling point. That way you don't freeze your engine and you don't boil it when it gets hots. Now, onward....

The easiest thing to do is go buy 50/50 premixed antifreeze. The ratio is ready to be poured right in. The parts store will be able to tell which antifreeze will work best for your Jeep. It more than likely just uses plain jane green antifreeze. That's what I put in mine.

Otherwise you can buy non-diluted antifreeze and add water to make a 50/50 ratio.

A 50/50 ratio is important because too little antifreeze is bad, and so is too much. For instance, a system ratio of 80% is highly ineffecient. That's why I'm suggesting the prediluted stuff. A ratio too low risks having your block freeze up and bust.

If you do add water, DO NOT use regular tap water. Only use DISTILLED WATER. It's cheap, and it's free from impurities, whereas tap water is good to drink, but it bad for your antifreeze system balance due to extra minerals, etc in that water.

You can buy distilled water at any grocery store. It'll be labeled distilled, not drinking, water.

Your coolant should be changed every 2 years unless you have extended life coolant.

Be sure to check for leaks so make sure you're not loosing too much antifreeze. The tank where you pour it is called the reservoir tank, or expansion tank. It's where the coolant goes when it expands when heated.

Be sure not to let animals near the antifreeze. It has a sweet smell to them, but it's deadly. Antifreeze can be recycled. But if you must dispose of it, carry it to your local hazardous waste facility. It only take a small portion of that stuff to taint thousands of gallons of water.

If you have a 4.0 six cylinder especially, be sure to follow these directions. The blocks and heads are iron and they will rust really quick internally with too little antifreeze is used. These are awesome engines often getting 200k miles+.

Coolant system


If your coolant level is dropping, I would suggest that you take a good look at the water pump. That is a very common coolant leakage probelm area on your vehicle. I change 2-3 a week.
Hope this helps.
