coolant loss

[chevyguy10]

Thanks for the reply. Those sound pretty reasonable and I might go in with a friend of mine to get one.

Do these meters also monitor brake abs systems or just engine functions.

That's one of the more useful things that the highest priced models have like I was saying. The 3130 and lower models don't read ABS, but I think it will read transmission codes. The 3150 and 3160 do read ABS, but they run about $50-$120 more than the 3130, let alone the cheaper 3100. I know you can upgrade the 3130 at least for $100 to read ABS codes. If you want to be able to read ABS, I think it'd be best to just get the 3150 or 3160. I wanted to get a 3150 or better a 3160 but then you are talking in the $200-$270 or so range. That's more than I wanted to spend on the scanner.

Thanks for the information, I probably won't spend that much either right now.

i have a 96' lumina,had the same problem,couldn't find any leaks outside some real small ones at the return bottle fittings,about 6 months later..i finally noticed wet marks on ground,and it was the lower intake manifold gaskets...i watched for the leak often and could not ever find it,one day after i drove the car and parked it...about an hour later the wet marks were on the ground..a friend did the job for about 300 including gaskets/thermostat...good luck and keep a bottle of water.

my message is to short?

99 lumina 3.1L, 198,000 mi., LIM replaced by dealer at 50,000 mi. I know the lower intake manifold (LIM) is common problem, but I wonder if a steady drip from behind the top area of water pump housing, left side, can be a cause of leak, or is it always the LIM. Can't see behind there to see if it is LIM or ?? Plan to replace LIM, but wondering if anyone has ever had water pump housing leaking between back of housing and engine block??.

if you are leaking at the waterpump, that means the internal seal is gone - replace water pump.... very easy job on the 3.1L.

the water pump is directly below the edge of the head so can easily confuse where the leak is.

hope this pic works.


Locate the 45 degree line ( in this // direction) in the pic where the intake meets the head. See the top of the water pump pulley at bottom of pic? The 45 degree line is right above the water pump pulley.

A leak here could be confused with a water pump leak.

I think you can feel behind the waterpump with your fingers and see if you get coolant on your fingers... if so, then that's probably just a water pump leak.

I am having problems with my coolant as well, but my lumina is a 91 will the LIM gasket Dorman or FelPro upgrade set work with the 91?

[Bearwulf]

Yes the upgrade is available for the '91 also.

Go to a Auto Zone or Advance store in your area if you have one, and they will run your diagnostic test for you for free..cost less that way
