Can an exhaust leak cause loss of coolant?
If you have an external leak you will notice coolant leaking from in between your engine block and the head. This usually will happen just below the exhaust manifold or the intake manifold. The last sign of a blown head gasket with an internal leak is to look for the presence of exhaust gas in your coolant.
How does a low flow radiator work?
temperature drop from inlet to outlet. The low-flow system has about a 20 degree drop. This looping through the core results in a greater drop in temperature compared to a straight through style radiator. This cooler coolant is then pumped directly to the aftercooler and then on to the engine.
What is the difference between downflow and crossflow radiator?
Downflow radiators are usually taller and narrower. Crossflow radiators are usually shorter and wider. Even if it fits, converting from one radiator type to another will require some custom fabrication.
Can a low coolant reservoir cause a leak?
The only symptom most folks notice is a low coolant reservoir. This can be very misleading and simply adding coolant will only allow the condition to progress. A much worse practice is adding water to the system. Water dilutes the corrosion protection of the coolant. City water may also contain chlorine, fluorides and several minerals.
How often does your car lose coolant with no visible leak?
However, the cooling system loses about 2+ quarts of coolant every 400 miles. I do not see evidence of coolant in the engine oil. A mechanic pressure tested the cooling system and reported that it held pressure, and he could not see any external leaks.
Can a 5.3L Vortec leak hot coolant?
You may never see a small leak when the engine and coolant is hot because it evaporates immediately after it leaks. The 5.3L Vortec has a dry intake manifold therefore the leak cannot be there. I finally sent an oil sample to Blackstone Labs ( http://www.blackstone-labs.com ) and they confirmed that I had coolant in my oil.
Can a leaking coolant cause oil to cloud up?
Coolant is leaking into the engine oil and a great deal of engine damage can quickly occur. False beliefs that mask the problem: People often dismiss this as a possibility, because the engine oil looks normal. The old ‘water causes the oil to cloud up’ test is false. Enough water may cause oil to turn milky over time.
