Red blinking light by temp cluster.

[Daniel Rodriguez]

Good evening, Everyone

 

Today I replaced the cooling expansion tank because It was leaking. Wow.. took me too long to do. After putting all together, I turned the car ON a bit to make sure everything ok and I noticed a blinking red light (slow blinking) next to the Temp gauge. The light stay ON after idle for few minutes. Is it possible the Temp sensor broke when I swap it? The coolant level looks good..

 

Thank you

Oops, I have 1999 Carrera 4.

May not be related. But after reading other posts,  I used the Black cap that came with new tank, Should I kept the old Blue cap?

Good afternoon,

 

I tested driving a bit to get the car to 180-190 temp the light still flashing.

I first tried to burp the car when setting around warning engine. I started to small coolant and when checking there was a costant drip (more like a hose was left somewhat open dripping from the side of the tank. I the metal burp lever down and stopped,  Did that 2 times and both times leal.

Is the burp system supposed to burp air or liquid?

The Temp did not go over the 190ish range. 

Following  notes from another post:

 

I checked if my sensor was missing, but it is where it is supposed to be.

 

Would the light come on if too much coolant? I noticed while hot the coolant was higher than the MAX line. Will drain some after it cool down and stays high.

 

I have video, see attached.

Thanks

You moat likely have an air pocket in the system which is causing the issue; this is not good and you need to get it out.  The normal procedure to refill this cooling system is to do it under vacuum using a special tool like the Uview Airlift system which evacuates the system and then pulls the fresh coolant mix in under vacuum, eliminating any chance of air being retained.  This tool can also be used to pull entrapped air out of the system the same way.

Thank you for the feedback,  let me look into this. I am assuming I need to empty the system or can I use it while coolant is in there?

 

Thank you

Yes, the common practice is to us the Uview Airlift to remove the coolant (under vacuum - then reverse it to fill under a vacuum.

You can test the coolant while it is out to see if it still meets your freeze protection needs.

Great, thank you @Loren

 

Will check out videos on this process.

I found a similar Cooling System Test and Refill Kit in Harbor Freight made by Maadox. Will compare both.

 

Thank you

Hello,  Everyone

 

I just received the Uview Airlift from Amazon. Looks fairly easy to use.

Hoping my little compressor can do the job. Will let you all know and post a picture or two.

 

Thank you

I am also following up with tank seller, I think the burp bleeder may not be working properly since it looked like when I opened the valve, the coolant seemed to be coming from the bottom of that adapter.

 

Thanks

Hello  Everyone,

 

Yesterday I tried to use my new Uview setup, but had a weirdvthing happening. First of all, Inonly empty the reservoir. The Vacuum gauge would got to green section but then return to middle red area, bouncing up/down. As if a valve was openned and that was it, was only able to drained 1/2 gallon or so. As per my previous message, I think the burp system is not working properly.  I have sent messages to FCPEuro for feedback.

 

Thank you

OK, the vacuum gauge will bounce as air pockets get pulled out; but if the bounce continues to happen, something is opening and letting air in, which should not happen.....

 

And if the bleeder/tank assembly is not a factory Porsche part, get rid of it and get a real one.  We have NEVER had any luck with aftermarket tanks.

And I just checked the outfit you bought yours from, it is NOT a factory unit, it is aftermarket. Get the real thing and be done with it.....................

Hello  JFP,

 

Wow, noted on bouncing and tank, will see about getting real one.

Word of advice: Multiple aftermarket parts sellers, like Pelican who is one of the worst in this respect, sell what they call "OEM" manufacturer parts like the coolant tanks and AOS units, which is at the best, very misleading.  The manufacturer in question may be an OEM supplier to Porsche, BUT NOT FOR THE PARTICULAR PART IN QUESTION.  In the case of your tank, Mahle is an OEM supplier to Porsche for engine parts like pistons; but they do not supply the coolant tank.  This, unfortunately, is quite common in the trade, so you need to know what you are getting before you spend your hard earned $.  In my shop, we do not do business with any vendors that behave this deceptively.
