im having problems with my coolong system for the engine it all started with the tempeture starting to fluctuate from 176 to 190 i changed the thermostat readded coolant and and the system pressurized and then it quit no more pressure on the cooling system and it wont repressurize am i fighting with a water pump that is starting to fail

 

Are you blowing white smoke out the tail pipe at all ?
Coolant level staying the same ?

Pressure in the system is caused by the coolant heating up and expanding,not the water pump.
The cap on the fill reservoir controls the pressure to 15 psi !!
Without the cap on you wont build any pressure ,the coolant will keep on expanding and the probably come out the over flow.

The thermostat regulates the temperature by controlling how much cool water from the rad recirculates through the block.

If your coolant isn't moving then you most likely have a Air lock and the pump will then be just cavetating and not pushing any coolant.

 

no smoke and no coolant in the oil and the coolant level stays the same 3 days ago the engine temp started jumping around like the thermostat was failing so i changed it and and the system built pressure like it should then all of a sudden it quit i changed the pressure cap and still it wont pressurize i know that it builds pressure from the coolant expanding it also takes circulation to help build pressure when i give it some gas you can coolant going back to the recovery tank but when its at idle its not flowing at all

 

When you refilled it did you turn the heater on full to fill the heater core up with coolant.
I still think you have air in the system.
At idle I dont think you will see to much flow into the tank.

 

yea i did that and followed th special fill procedures

 

Filling Procedure




Notice: The procedure below must be followed. Improper coolant level could result in a low or high coolant level condition, causing engine damage.

•Close the radiator drain **** by hand.
Notice: Refer to Fastener Notice in the Preface section.





•Install the water pump drain plug (1) if the plug was removed during the draining process.
Tighten
Tighten the plug to 22 Nˇm (16 lb in).

•Lower the vehicle.



•Remove the upper radiator inlet hose from the passenger side radiator.
Important: Use a 50/50 mixture of DEX-COOL antifreeze and clean, drinkable water.

•Slowly add a mixture of 50/50 DEX-COOL antifreeze and deionized water to the engine through the upper radiator hose.
•Install the upper radiator inlet hose to the radiator.



•Slowly add a mixture of 50/50 DEX-COOL antifreeze and deionized water to the cooling system until the coolant reaches and maintains a level slightly above the cold fill line on the surge tank. Refer to Approximate Fluid Capacities .
•Install surge tank cap.
•Start the engine.
•Run the engine at 2,000-2,500 RPM for 3 minutes.
•Allow the engine to idle for 30 seconds.
•Shut the engine OFF.
•Top off the coolant as necessary.
•Inspect the cooling system for leaks.
•Rinse away any excess coolant from the engine and the engine compartment.

 

i did the fill procedures

 

How do you know the system isn't holding pressure?

 

I also have questions for this matter, if you knows I would appreciate it.

1. Which is the normal temperature range a 07' supercharged should have?
2. How do I know when the dex-cool/water level is high or flow? enough or insufficient?

Thanks

 

1. 180F - 230F
2. On the engine coolant reservoir tank it is maked with a "cold fill line". When the car is cold (ECT typically under 120F) the coolant should be filled to that line. When cold if it is under that line you need to add coolant, over that line the system is overfilled.

 

When I did my water temp gauge I had put in fresh coolant cause I emptied what was in there out. I used Prestone DEX COOL. I never added any water, I didn't know I was supposed to? My car has been fine since then and that was maybe a year ago? So I should add water to it?

 

It's best to use the prediluted rather than add water, since they use de-mineralized water.
Do not use concentrate! Prestone has *Quick fill* (diluted)..on the left. The right is the concentrate.

 

I used the one on the right. So I don't have to add anything else? And I never did the whole turn the car off put the heater on etc thing either and the coolant is always at the cold fill line when its cold so I guess I'm alright?

 

The container on the RIGHT (as you view it on the screen) is CONCENTRATED! The one on the left says 50/50 concentration.
This one:




I assume you used that one then. You have to dilute to a MAX Concentration of 70 coolant/30 water..50/50 being optimal. If you used the other one you have 100% concentration!
If that's the case, ...drain it about half and refill with distilled water.

You want to use this:

 

Ugh... so like poland spring water? I'm a little nervous, winters coming wont the water supercool? Distilled water supercools at temps below freezing. It doesn't turn to ice, but a shock to it or an ice crystal can freeze it solid.

 

no not spring water just distilled water you can buy it at the grocery store just make sure it says distilled on it

 

 

i thought spring is distilled whats distilled then? well off to cvs tomorrow i guess. good thing i asked about this i would of never known. i thought what i had was 50/50. what can happen to my engine if i never put water in?

 

Distilled water has all impurities (minerals and matter) removed. Spring water is simply filtered, but not distilled. If you use any water but distilled water the Dexcool will attach to the impurities and cause sludge.

If you run straight dexcool with no water you can cause water pump damage and dexcool with no water does not cool the engine correctly. Your ECT readings may look ok, but that is because the dexcool is not transferring heat from the engine correctly and the engine is probably running WAY to hot.

 

**** i hope i didnt damage anything i been running straight coolant for at least a year year and a half. maybe thats why it took forever to get heat in the winter

 

Alright I finally got around to doing this. I siphoned half out then filled to cold with distilled water. Then it looked too watery so I siphoned again and added coolant. It still kind of looks watery. What happens if I have a higher % of water than coolant?

 

Just go get the 50/50 quick fill.

If you get too much water then the coolant could freeze if it gets too cold. Normal coolant won't freeze till -34F, but the further from 50/50 the sooner it will freeze.

 

dammitttttttttttttt

 

Could I add prestone extended life coolant (no dex-cool) to my already added dex cool reservoir tank? No problem?

 

Use a coolant tester to find out your mix.
Don't mix them. Unless of course you want to have to thoroughly flush the system again soon when it turns to snot.
