Question about 2004 Chevrolet Tahoe

2 Answers

Losing coolant, no large puddles in garage when parked. Having to fill up reserve about once every couple of weeks. Taken it so several places and the pump is fine, they can't find a leak at all. It has to be going somewhere. The last place changed the oil and said the oil was thick like molasses. Would coolant do that?

If engine oil was thick , somewhat " Russian Dressing " like, I would look for coolant mixing with engine oil. Causes could include leaking internally head gaskets, cracked heads, intake manifold gaskets, etc. Initially and unfortunately the intake manifold, and cylinder heads will have to come off. Then a complete visible inspection of ALL GASKETS will be required as well as CYLINDER HEAD AND BLOCK for cracks. After repairs are completed don't forget to change the oil and filter again. Hope this helps

I topped up the coolent 6 weeks ago and today the well was empty again, I drive approx 100 miles a day and it's been warm but this hasn't happened before and I've had the car a few years. Any...

you are losing coolant, either through a leak or out the tailpipe. if there is a green or orange puddle on the ground where you generally park the car it is a leak. Someone is going to have to put the car up on a lift and track down the source of the leak. If your exhaust tends to be whitish, and sweet smelling then you are losing coolant through a breach between the cooling and combustion systems. Pull the oil dip stick out and remove the oil fill cap. If there is a foamy residue on the stick or the bottom of the cap then your coolant is getting into your lubrication system and that is no good either.

In any event this needs immediate attention or you will be stranded somewhere with a baked engine.

My car heats up in stop and go traffic

There are several things that could be wrong here.
  • Head Gasket, if your car is loosing power and leaking fluid, thats a good sign.
  • Radiator could be bad
  • There could be a leak somewhere. You can check it yourself and just look to see if there are any puddles after you park.
  • There could easily be a thermostat problem. Take it to a garage and get it checked,
As long as it's not leaking or losing power, then it shouldn't be a big fix.

Temp keeps over heating even though it has coolant, but goes thru coolent like nothing have to fill it up once a week

If your are blowing white or gray smoke out the tailpipe you have a head gasket leak. Or you may just have an leak, you should see a puddle if going through it in a week

I am finding small puddles of coolant on the garage floor... any ideas what it could be. I just had the coolant flushed and filled over 2 months ago.

If there were no leaks prior to the cooling system being flushed I would first check the drain petcock on the bottom of the radiator to ensure it is tight and/or not cross threaded if it was taken out completely. Next check all the obvious things like your hoses for any bulges or visable damage and check to make sure they are all clamped and secure. If all checks out ok so far drive it around until it reaches operating temp. park it open your hood and look for any leaks while it is hot and the cooling system is pressurized.

Every two days coolent in reserve has to be filled

Antifreeze has an odor. With the engine idling sniff the tailpipe, if you smell anitfreeze you have a situation where antifreeze is getting into a combustion chamber and is being passed out the exhaust. This is not good and requires an expensive repair ASAP. If no odor there, unscrew the oil fill cap, turn it over and look for foam. If it is foamy then your coolant is getting into your lubrication system, again not good and a repair is needed. If it is not being sucked into the engine, then it is leaking somewhere and that should be easy to spot. A green or orange puddle where you park.

99 Sunfire Coolant keeps dumping

You need to find the source of the leak. it hasn't overheated yet because you keep catching it and re-filling. From your description, it sounds a lot like a bad water pump seal (part of pump) but without physically looking you can't be sure of that. when the pump seal begins to fail, internal pressure while running often will drive the seal tighter against the shaft stopping the leak. as pressure drops as the engine cools, the seal relaxes and permits seepage.
With time, that will change and it will leak all the time.

Radiator fluid evaporation or leak?

Just had the same problem! I have never had any problems out of my van and just had all fluids checked a month ago before going on vacation. One day it just started overheating and I had to urn the heater to pull the heat off of the motor to keep it cool enough to get it home. I put over a gallon of coolant in it and filled up the reserve tank. The next morning I took my kids to school about 4 miles away and my van started to miss really bad and the check engine light would come on every time I pressed down on the accelerator. I took it home and opened the hood and the reserve coolant tank was empty in just 8 miles of travel so I called the dealer and had them pick it up on a rollback since it is still under warranty. The dealer said it was a leak in the rear heater pipes that circulate antifreeze/coolant to the rear of the vehicle to supply heat for the rear heater and the miss was from the heat of the engine burning the spark plugs. So far it is a dealer item only and parts and labor are about $352. The vehicle will not leave any puddles when running while in park, only leak while moving, so they tell me. The dealer bypassed it somehow until my parts come in and my van drives fine. The pipes (maybe hoses,unsure) are actually a series of 3 that must be replaced. I may try to change them myself if they are just hoses.
