2003 Chevrolet Coolant Flush

I need to flush the coolant on my 2003 Chevy 1500 Suburban. I have done this in the past on other vehicles. However, I cannot locate the pitcock-sp? valve on my Sub.

Is there a way I can do it myself? or does it require a dealer type apparatus?

Thanks!

I see no problem you doing this yourself. First i would pour some coolant flush in it and run it a couple of days, secound instead of useing the pip **** to drain it, when its cool remove the bottom radiator hose from the radiator and drain it that way, its faster and you will get more out of the engine block that way, (unless your going to pull the block drains.) Just make sure you get it full when you refill it so you don't get any air pockets in the system. What i do is pull the thermostat and fill the engine block from there and reinstall thermostat and then the radiator that way i know that i did not get any air in the system.

I have a blackish color in my coolant resevore. Is this due to due to demodox coolant or do i need a radiator flush done.


You mean DexCool coolant? If it's black, you need to flush the system and refill with the recommended coolant. A radiator flush only removes 1/3 of the coolant in the system. YOu want a full coolant flush.

Someone added water to my DEX-COOL only 1996Chevrolet. 1500 suburban. What should I do. I only ran it for about 45 miles


Was the water added to the coolant reservoir or into the radiator? If the coolant reservoir it's a simple matter to unbolt it, drain it, reinstall and refill to proper level. If water was added to the radiator, it's best to drain the coolingg system and refill with the proper 50/50 mix of Dexcool. Water in the radiator will not hurt anything in the short term, but will not provide adequate protection.

How do I drain the coolant from my 2004 chevy suburban


locate your radiator ( usually bolted to the front of the car under the hood) and look at the bottom and find a little plug that screws off and take it off. Make sure and have a bucket cause there will be a lot of coolant that comes out. then take the bottom radiator hose off of the radiator ( not the water pump) and there may be some more coolant that comes out there and that should be it. If the coolant is really dirty i recommend just taking it to a shop so they can perform a coolant flush and get all the dirt and grime out of your engine before it clogs up.

Hi:
The only way to clear up a clogged heater core, is ti have the coolant system flushed. Take you car to a reputable radiator shop. They will add a radiator cleaner to your heater core directly, and let it sit there for a while. Then the vehicle will need to be started and allow the thermostat to open. Once heated, they will flush out the entire coolant system, and replace it with new coolant. The cost will be approx. $100 - $200.......better than the $1500 to replace a heater core. A well maintained vehicle should have this procedure done every "5" years.

My equinox temperature gauge heats up when i idle. what could be the casue of this?


many things can make this happen
I would inspect all hoses to see if none are collasped
Also change the thermostat and coolant if not done in the past two years. Flush the old coolant out with a flush kit made by Prestone or equivalant
You may see a big change in performance. If not a blockage can be in the heater core or radiator but I don't think so for this vehicle is 4 years old only

once truck is warm check both heater core hoses to make sure they are both warm if not then check the cold water valve could be stuck shut not allowing coolant to travel in to heater core.

It might fix the problem but you may also have a shift sensor that is starting to go bad as well take you suburban to autozone or an o'reillys if you have one of those auto parts stores near you and they can do a scan on all the sensors to tell you if your vehicle is showing any problems with any of your sensors I hope this helps you out.
