Small problem turning BIG!?

[EUROchop]

so as some might remember, i posted the other day that my 30v 2.8 was expiriencing some fluctuations in the coolant temp readout.

as i wait for my new coolant temp sensor to arrive, the problem seems to have worsened.

as of today, my car doesnt just run a little bit hot, it runs hotter and hotter the longer the car is running...so much so that i saw the temp warning light come on twice on my way home from work.

one other thing that i am noticing is that when the temp guage goes about 3/4, my oil temp goes up a bit into the 250 range.

i am hoping that this coolant temp sensor will solve all but these new problems are scaring me...BTW i do have coolant in the car and have no other ideas as to why this is happening

any hints or advice?

What color is your coolant?

[EUROchop]

green...

[ILoveT]

Did you put in the green coolant or was it green when you bought it?

Why I ask is, I ran into problems similar to yours because the PO didn't flush the OE G12 before filling it with green coolant. A complete coolant flush got rid of my problems.

[ILoveT]

Oh by the way, the original coolant is pink.

car has had green coolant since ive owned it, which is about 5 years now

cant hurt to try flushing to coolant tho

any other opinions?

[ILoveT]

Try flushing the coolant.

The way I did it was flush all the crap coolant out and then run a couple gallons of distilled water through it and drain it again. Then add G12 or the green stuff.

I'm guessing your fan is not kicking in??? If anything turn on the a/c so that both fan's are running this should help little bit to cool down the car.

Yes go get yourself G12+ and change your coolant

since your oil temps are rising, I would say the engine actually is running too hot.

Does the coolant temp ever get too high when driving at freeway speeds? If it still does, its not the fans.

BTW i have to run my car with the heater on FULL or else it would just keeping heating up and showing temp warning light...if that helps with diagnostic

[MattzWarsteiner]

The heaters like a little radiator and helps draw heat away from the engine. That tells me most likely your water pump is doing its job.

Now what about on the freeway < please see my earlier post.....

I can't stop laughing.

Wtf? When was the last time you changed your thermostat?

fans are working fine, car heats up on freeway more than i noticed on the road.


Previous owner "supposedly" had thermostat changed at 80k, pushing almost 130xxx now

Matt called it.

I can't stop laughing.

i just got why you posted this pic, and it is hillarious lol

Hahaha!

If it is heating up on the highway that means no coolant is flowing so it can't be cooled off. Since no coolant is flowing your water pizzump may be baaad. Or sludged up because of a mix of 2 coolants. Flush it first because that is the cheapest option, like $10. If that doesn't fix it, water PUMP!

Let's just clarify that G12 is more like $24. Honestly, I doubt there is any real reason to run G12 but I'd rather be a sucker and not have to worry about it.

I have to fix my dad's A4 because he mixed coolants and it's sludged. We were thinking it's the thermostat but maybe it's just sludge? I think I may just replace his Tstat anyways because it's only $20.

i was hoping it might not be the water pump but ill try flushing the coolant first and see what happens...

i know im supposed to use 1 part coolant per 1 part water, but how much of each does that equal to?

ive read there is a place to find G12 for $25 a gallon, anyone know where?

I never said to run G12. You can run straight water....
