Bob, I'm having issues with my 2004 cadillac cts 3.2 base

Customer Question
Hi Bob, I'm having issues...
Hi Bob, I'm having issues with my 2004 cadillac cts 3.2 base model. Overheating fast. I flushed the system and it still does it. I'm debating on if it's the thermostat or radiator.

Hello and welcome. My name is ***** ***** I will be happy to assist you today.
.
That could be the thermostat. Normally you can tell if the coolant spits out as you try to fill it when the engine is running for a few mimutes.
.
They are sometimes bad about the radiators clogging up and causing an overheating. You can have that tested at a radiator shop or feel around the core when the engine is hot to see if there are any cool spots that would indicate a clog.
.
However, with any engine that runs hot, overheats or has been overheated it is best to check the integrity of the engine, (head gaskets and heads, etc.)
.
The first thing that you want to do is check the cooling system for any exhaust gases. Make sure that it’s full first. There is a tester for that, that you can get from Autozone for about $20. They will normally lend you the tester and you just buy the fluid for about $8. It comes with instructions, but there is a blue fluid that is used in it, if the fluid turns yellow, that is exhaust gases.
.
Block tester available is:
Napa BK.(###) ###-####
OEM/Block Tester AUTOZONE
Part Number:
27145

.
*****You will want to check it at different RPM’s and at different temperatures***
..
.
If there are any exhaust gases in the cooling system, that will cause more pressure than desired and will allow the engine to burn coolant and/or heat the coolant up too high. Most times not filling the crankcase with coolant either and not smoke out the exhaust.
If there are, then there would be an internal engine problem, like a head gasket or head.

I have a 2006 cts, RWd. I have a 2006 cts rwd with 3.6
hi I have a 2006 cts rwd with 3.6 engine. 131,000 miles. Transmission was going out so I had it replaced with a used tranny from an 07 with 46,000 miles. The transmission seems to be working fine in all ranges, shifting ok but I still have a random at different times while driving a sound that seems to be coming from the transmission area like a short buzzing or humming noise. Usually happens while steady rpms, not under acceleration. It started making this same random noise in the previous transmission when it started to go out. Finally it quit shifting into gears and in overdrive the previous trans would run at 3000 rpms at 65. This new used trans seems to be making the same just random "buzzing" or humming noise. It doesn't stay for very long. Just comes and goes. Am I looking in the right place or is it just coincidence that this is another issue that started when my original trans failed. Also, there is no transmission dipstick or a way to fluid replace in these units. Is this trans maintenance free? I can't believe that an automatic trans would be maintenance free. … read more
