Question about 2001 Chevrolet Suburban

1 Answer

2001 Suburban. I have to add coolant about every 40 miles. Cannot locate where it is leaking from. Even had 2 pressure tests with no results. Oil looks clean, and I don't see liquid coming out of the exaust. Started with a new coolant reservoir cap. What's next?

Have a compression check done on it,, if the problem is a head or head gasket you could be making steam which doesn't show up hardly at all while driving , the heat from the Catalytic converter will reduce the liquid that you could see on older model cars at the tail pipe ,

2005 Chevy Avalanche - loosing coolant - not leaking on the ground

have a compression test done to check for head gasket problems . check for cracked head . Check for corroded faces where the coolant can get into the exhaust system . a pressure test done and check for leak behind the water pump body. Check for leak in the heater core.AS to the oil pressure problem replace the oil sender unit and check for the results.

I have 98 neon 2.2L DOHC that uses coolant, just a little every time I drive it, I don't see any leaks and no coolant in the oil and cannot smell any coolant in the exhaust. Will have to add about a quart...

I would1st Pressure test the cooling system for leaks. Also, be sure to pressure
test the Radiator cap as well.
Assuming pressure testing the system shows no leaks, and if your radiator cap is
2 or more years old, then most likely your radiator cap is defective. Replace it!

2001 Suburban going thru coolant

The most common sources of leaks that I see on these are where the water pump bolts to the block, the weep hole on the water pump itself, and the seam at the plastic end tank of the radiator [inlet end of radiator]. You'll almost never see any coolant drip on the ground from any of these leaks because of where they are, how slow they leak, and the fact that when the engine is hot the coolant vaporizes about as fast as it can leak. I have a tool that I put on in place of the radiator cap which allows me to pressurize the cooling system to about 17 psi. If its an especially tough one to find I'll leave pressure on the system overnight and come morning the leak is usually quite evident. I'd start by looking at where the water pump bolts to the block as the gaskets there are prone to leaking the most. Good luck, hope you find your leak!

The oil pressure in my 1999 chevy suburban went down today and i dont know why it says that. it says that i have oil. plus for the last couple weeks i have had to add water and antifreeze to my radiator...

5.7L engine? That engine is natorious for the intake manifold gaskets leaking. They leak coolant out of the corners where the manifold meets the heads. They usually don't leak all the time though because the block and heads are cast iron and the intake is aluminum the expansion and contraction rates metals are different. As far as the oil pressure goes I would put a mechanical gauge on it 1st. for test purposes. It could be just a faulty gauge.

Have you had a block test done?A coolant system pressure test? I would check this and also if you have rear heat and air check at the rear of vehicle to make sure you are not wet.Where there is loss it must go somewhere.

2001 chevy silverado 5.3 ltr I am adding 1 gallon of antifreeze between oil changes. I am not seeing any in the oil, and it not leaking. Where is it going?

This is one that you will need to do some careful looking to find. every hose connection needs to be looked at for damp residue as well as all gasket parting lines (thermostat housing, head to block parting lines, intake manifold ends etc.) You may also need to have a shop to a radiator pressure test as well as a cylinder leakdown test (which will pick up on most internal leaks) If seepage is very minor, coolant can burn off or boil out before reaching a noticeable level inside the engine or even at a gasket to the outside. A small crack between the valves in a cylinder head can be so small that it goes unnoticed when exiting along with exhaust. A small leak now may be difficult to find but locating it now is better than waiting for a larger failure. It may turn out to be something simple as a bad cap on the radiator or the shaft seal beginning to fail on your water pump...letting it go can eventually cost you an engine.

My 2001 ford windstar lx van smells like coolant when i drive

Several things to check. Have the cooling system pressure checked. A quick and simple test. Puts system under pressure and helps to locate a leak. The coolant doesn't just go away, it's got to be leaking either externally or internally. Be sure that the radiator cap is checked too. It needs to maintain the proper pressure for the system
Sound like coolant is leaking on the exhaust system. This can result in the smell and you will not see a leak as it is evaporating when it hits the hot pipes.
Good Luck

High oil consumption 2001silverado 4wd, 4 door 6.0

Every manufacturer has a guideline.  But a quart every 1,000 miles seems higher then necessary.  Try the easy steps first. 1.  Check the PCV valve if clogged will caused pressure in crankcase and oil burning. 2. Remove spark plugs and perform visual inspection.  IF electrode is covered in gook(technical terms, sorry), then oil is leaking into that cylinder.  Most likely cause would be faulty valve stem seals. 3. Worse case scenario, engine oil rings are leaking.  If all else is good.  Perform compression test of each cylinder recording measurement, then add two small squirt of engine oil into each cylinder as you perform a second round, complete both dry then wet compression test on each cylinder before proceeding.  IF any cylinder shows a more significant increase in compression then it would indicate that cylinder's oil rings are faulty.  This is a major repair.  Keep me posted
