How to remove and install an exhaust manifold in V8 engine on Chevrolet Colorado?

Before proceeding to the process of the removal of the exhaust manifold, you should find the button that stops the engagement of the negative terminal of the battery and then relax it. If you have to remove a left side manifold, then you should loose the left front wheel lug nuts, lift the car and secure it with jackstands. It is common for these to be rusty, use penetrating oil on the exhaust pipe-to-manifold studs and nuts. In the case of a left-side manifold, pull off the left front wheel and the inner fender splash shield. Remove the exhaust pipe/catalytic converter pipe by loosening the nuts that attach it either to the exhaust manifold or directly to the cylinder head; the latter requires the removal of spark plugs. Where working on the right-side manifold, the oil dipstick tube should be evaluated and, if necessary, removed. If the manifold requires replacement, then unbolt the heat shield and manifold mounting bolts; then take off the exhaust manifold and gasket. You should also inspect the manifold for crack as well as clean the bolt threads to ensure there is no damage then ensure that the mating surface is clean by scraping out all the carbon deposit and gasket material with a gasket scraper but be careful as not to damage more the aluminum cylinder head. Place the heat shields, bolts, and gaskets over the manifold and make sure that the retaining tabs will just click into place while being put in. A medium strength thread locking compound should be applied to the threads of the bolts a 1/4 inch wide band starting at the 4th thread and excluding the first 3 threads. The manifold must be placed on the cylinder head and the mounting bolts tightened just enough to be held in position by the fingers. When tightening the bolts, it is necessary to begin with the center and move to the ends, tighten them in two stages to the required torque, if necessary, it is necessary to bend the protruding part of the gasket in the exhaust manifold back to the cylinder head. The rest of the procedures aim at the reverse of the above process of disassembly. Then, switch on the engine and search for exhaust leakage.

Chevrolet Colorado Exhaust Manifold

The Exhaust manifolds of Chevrolet Colorado vehicles are responsible for channelling hot gases from engine to the exhaust system so as to optimize engine performance and minimize dangerous emissions. Located at different positions depending on the design of the particular engine, the manifold play crucial role of avoiding the reversion of the intake hence facilitating the right airflowing required for efficiency of the engine. Chevrolet Colorado exhaust manifolds have undergone a number of changes in the earlier models using mainly cast iron but now more advanced models using stainless steel are available. There are modifications or call 'headers' that increase performance by decreasing the flow resistance and increasing the rate of the exhaust gas. These headers can help increase the efficiency of the engine by providing pressure difference that helps exhaust gases be cleared. The aspects concerning the design and production of exhaust manifolds include converting and material differencies that may exert a measurable influence on the vehicles' efficiency, which makes having an absence of the properly fitted exhaust manifolds' substitutes important for Chevrolet Colorado.

Each OEM Chevrolet Colorado Exhaust Manifold we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
