Pushing water out of the reservoir
« on: 27 October 2017, 23:30:06 »

When the car starts to warm up it pushes the water out the reservoir and will cause it to overheat.
I don't  have water in the oil, nor do I have oil in the water and none coming out the tailpipe, so i don't think its a blown headgasket.
I have had a diesel at work do the same thing when the egr went bad.
Any help would be appreciated.

I hadn't thought about the radiator. I was gonna take the thermostat out and see if it fixed it, but it doesn't look like it comes apart from the housing and it isn't that easy to get to here, not like my old gm

No, thermostats on a V6 aren't the easiest of things to get to  :( http://www.omegaowners.com/forum/index.php?topic=90647.0
Might be an idea to buy a new transfer pipe before you start the job,  or at least know you can get one as they have a habit of not letting go of the 'stat

Is it straight away, or as it heats up?

It starts after about 5 minutes, as it heats up it seems

Hmm, before it blows out of the cap, what is the temp doing?

Persumably the aux belt is in tack, and the water pump is spinning?

That sounds like the thermostat to me. Considering what a pain it is to do on the V6 and how cheap they are to buy(you can buy just the 'stat without the housing but it's not worth doing), I would replace it with a new one. Checking the water pump would be a good idea too.

I thought I had it fixed. I took the thermostat completely out of the housing (mainly because I would have to order one, because the one I bought was made different), so I know there isn't anything to block it there. Drove it for 15 minutes and it pushed the water back out steaming. The temperature gauge was middle of the gauge, so not overheating according to the gauge.

I did have the timing belt, water pump, and components replaced about 2000 miles before this started happening. All replaced with AC DELCO parts. How can I tell if the Water Pump isn't turning without having a look into the radiator?

The only other thing I notice is the oil pressure has been different since the timing belt replacement, It will be at 75 until it warms up then it drops to where it should be and operates as it is supposed to.

Is the rubber washer on the cap in good condition?

Did you have the problem before the new pump was fitted? If it is suspect then you probably just need to dive in and take it out to inspect it.

Check if the following may point to something;

A. Are the Auxilliary radiator cooling fans coming on when needed (search for a document on this forum on how to test the proper relay operation)

Note:  If possible make sure that you keep the coolant strength up to par while replenshing with de-mineralized water or distilled water. Various coolant strengths will affect how much the cooling fans are needed and how often these come on-off.

Good luck

Could you clarify the coolant strength versus fan operation for me, please?
Do the fans come on more or less as coolant strength increases?

Coolant strength? The fans have no idea what that is, just goes on engine temp. There is a sensor/connector is on the coolant bridge, but I can't remember if that's just for the dash  :-\

The temp doesn't get high (according to the gauge)

Coolant is dex cool 50% as recommended, although I drove home with probably a 25% mix since I refilled with just water
