Antifreeze is antifreeze like salt is salt and sugar is sugar. Depending on where you live and how cold it gets will determine how diluted you need to go. You can buy an inexpensive antifreeze tester at an auto parts store. Usually down to -10F will suffice but if you are up near Canada go lower. The color is a dye and it doesn't do anything. VW wants you to think a red dye makes a difference, it doesn't. I have a 2001 Beetle and a 2001 Jetta that I have used Prestone antifreeze in for years and never had a problem I fill mine in through the antifreeze resevoir. I did have to replace the water pumps in both vehicles last year as it was leaking and not pumping the fluid through consistantly. If you want to change the antfreeze there should be a plug at the bootom of the radiator. If you remove it a large roasting pan should hold what you have in the radiator. Dispose of properly as it is probably poisonous and will kill pets and animals. You can run a garden hose through the top of the radiator while the engine is running for a fa minute or so to get scaling and slime out. This is what is known as a radiator flush. Be careful to always have water going through the engine when running. Put plug back in bottom and refill with anti-freeze. They do make a non-toxic antifreeze which is propylene glycol based versus ethylene glycol based. They work the same but the propylene based won't kill pets shoudl they lick it off the ground and cost a little more. Hope this helps.

if you do not have exsperiance or have the tools for it.
go to a garage.it will cost you double cause its an delicate,
job .that can go easly wrong.you have to drain all the water.remove,
all tubes -airfilter-carburator-valve cap.you need special tool to untighted the bolts from head gaskit in the wrigh order.get the head carrefully off.the head must be checked in the garage cleaned flattend.
put the new gaskit in the wright way back.then the head bolts must be tighten also in the right order and tension.put all parts back fill the cooling and get the air out the radiator.also the new has to rodate for atleast 500 km.there are some books or manuel how to do it.
not clear on a cooling module...there are relays which operate the cooling fans is this what you mean? there is atemp sensor that has wires connected to it mounted in the block that will tell the fans to come on to cool the car..if this sensor is bad the system will not function properly hence with the fans if they dont come on the car wont cool down either..need each one checked and replace whats broken..good luck..
what is the make and model?. do you have a mazda? if you have a mazda and you put in dex cool and it is only in the over flow then just drain the over flow. if it is in the radiator just drain it. sounds like it is only in the over flow . just unhook the hose from the over flow and let it drain out
to change the coolant in any engine you need to firstly remove the bottom radiator hose when the engine is cold not when the engine is hot and drain the whole system. You then need to get some coolant from your local supplier and it will tell you on the container the proper ratio of water to cool it. Once you have put to cool it in top up the system with clean water.Regards
Please check the coolant drain plug. It is a bolt on the underside of the water system meant to drain the cooling system if need be. May that this bolt is missing or it is loose. If missing replace it else tighten it.
If it has been a long time since your oil has been changed, the fuel smell is somewhat normal. Changing your oil and filter will take care of that. Unless you are having problems with the fuel injectors, there is no need to replace them. They have nothing to do with the fuel smell of the oil. If you feel you need new injectors, they will cost around $50.00 each. Your temperature guage will probably work if you replace the Coolant Temperature Sending Unit, cost is about $10.00 for the 6 cylinder engine. If, by keeping your Jeep the coolest possible, you mean the engine temperature, then maintaining and servicing the cooling system regularly will be all that is needed. Change the thermostat, drain and flush the cooling system and add the recommended quantity of a 50/50 solution of antifreeze and water. If you have an electric cooling fan, make sure it is operating properly.
Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it. If you have basic mechanical skills and tools you will have no problem replacing a water pump.
As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it. However no matter how good our explanations are it just can't compare to a good repair manual. A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right. I personally like Haynes Manuals. I hope this helps.
remove all accessories from front of engine -alt and ps pump,then drain cooling system ,remove upper intake- remove valve covers then lower intake.Then take out push rods to remove gasket(keep push rods in order as exhaust rods ar longer-will bend valves if installed wrong-get a piece or card board and punch in 12 holes 6and 6opposite each other,then put push rods in it)please not their is an updated gasket set from FEL PRO that has all you need to repair the problem with updates torque specs for lower manifold in the box REMEMBER change motor oil befor starting-you can even pour a little oil onto lifters before putting lower back this is to get any coolant from upper block to run into pan before oil change,if not knocking will occur in the next week
its a pitcock facing the cab bottom of the radiator, plastic flat. once you find the pitcock just put a bucket underneath and turn it.then refill. if you want to flush(run fluid thru to clean it out) the radiator id suggest taking it in. you dont have to flush it every time you change the coolant out.
