How long does coolant last in a truck?
Depending on the vehicle and the coolant, the average time between flushes is two years or 30,000 miles for silicated coolants and up to five years or 100,000 miles for an extended drain coolant. You can tell which type of coolant you have by the color.
How do you test for coolant leak in intake manifold?
Add the coolant leak test dye to the radiator fill cap. Replace the cap, and start the engine, letting it warm up completely. Shut the engine off and let it cool so you can work around the engine comfortably. Put on the yellow glasses and shine the ultraviolet light around the areas where the leak is in question.

One of the recognizable symptoms of bad intake manifold gasket is coolant leaks. Intake manifold gasket works as a seal for the coolant of your car engine. Generally, when this seals were damaged, then the coolant will flow out over the seal.
Where does the gasket go on an intake manifold?
This seal can be made from metal, paper, rubber, or a combination of them. However, there is no gasket more important to the engine than the intake manifold gasket. This particular gasket goes in between the cylinder head and the intake manifold in order to provide a seal there.
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.
What kind of intake manifolds do GM engines use?
Chevrolet Performance intake manifolds were designed specifically for GM engines, so you know they will deliver OE performance. Dual-pattern carburetor flange is approximately 1/2″ lower than the 1970 LT1 intake, yet produces the same horsepower NOTE: Open carburetor spacer is not recommended for use with dual-plane intake manifolds.
What causes a leak in the intake manifold?
The intake manifold gasket may develop and external engine oil or coolant leak. In some cases, an internal coolant leak may occur causing coolant to mix with the engine oil. Our technicians tell us that operating the engine with a coolant/oil mix can result in internal engine damage. Replacing the intake manifold gasket should correct these leaks.

Where is the coolant bypass in a small block engine?
Blocks manufactured in 1995 or earlier have thermostat bypass passage from the block directly to the water pump. If manifold is used on 1996 and later engines (which do not have the bypass in the block), you must run a coolant bypass line from the manifold to the 5/8″ hose nipple on the water pump (passenger’s side).
