Awesome Quality ndk oil seals Exquisite Craftsmanship.How to Install a Head Gasket.The head gasket is found between the engine block and the cylinder head or heads in a V-type engine. The gasket functions as a seal that prevents the combustion process from leaking into the coolant passages that surround each cylinder. In many cases it seals oil passages from coolant passages so the fluids do not mix.
The price for an independent mechanic to replace a head gasket can be high due to the time-consuming labor involved, so, it is essential to know why you need to replace the head gasket. Have a professional ASE certified Master Auto Technician inspect your vehicle to conclusively determine whether or not your car needs to have the head gasket replaced. The purpose of this article is to help you learn how to install a head gasket to save money.Awesome Quality ndk oil seals Exquisite Craftsmanship.
1Obtain a service manual for your car’s make and model. It will include step by step procedures with images that explain how to replace your head gasket(s). It will also list any special tools that you may need.
Drain all of the oil and coolant from your engine. Remove the parts that are on top of the head gasket. Refer to your car’s service manual for specifics, but in most cases this involves removing the exhaust manifold, the intake manifold, valve cover and drive belts. On many engines, you will need to remove the timing belt or timing chain. Be sure to study the timing belt/chain alignment procedures and be sure you clearly see the alignment marks before you disassemble the timing components.Catalog each part as it is removed. Either take pictures or write down each part to help you remember where everything goes once you’re done. The gasket will be a thin piece of sealing material that can be seen once you remove the head.Awesome Quality ndk oil seals Exquisite Craftsmanship.
3Check the block to be sure no warping has occurred and send the head or heads to an automotive machine shop to be pressure tested. If the pressure test reveals no cracks, have the machine shop resurface the head(s). Don’t ever re-install a cylinder head that has not been professionally re-surfaced. Check the service manual for the head bolt specifications to see if the bolts need to be replaced whenever the head gasket is replaced.
4Clean the surface of the head and block. Do not scratch or remove any metal from either, as this may prevent the head gasket from sealing.
5Clean the bolt holes that tighten the head to the block.
6Fit the head gasket onto the block. Use gasket sealant when specified by the manufacturer, and only use the directed amount in the particular places. Deviating from the manufacturer’s recommendations can cause damage to the internal parts of the engine.
7Place the head onto the block with the head gasket in place.Awesome Quality ndk oil seals Exquisite Craftsmanship.
8Use a torque wrench to tighten the head onto the block. Check the service manual for the head bolt torque sequence and then amount of torque that needs to be applied for each step. Some head bolts require 3 steps plus specified degree rotation as the final step.
9Replace the other engine components you removed.
10Set the timing belt or chain back to the proper alignment marks by carefully rotating the camshaft and crankshaft. Check to see if the engine is an interference type of engine. If so, there is a very specific method to rotate and set up the camshaft to crankshaft timing so you don’t damage or bend the valves! If equipped, install the distributor so it is properly timed with the number one cylinder. If applicable, adjust the valve clearance to proper specification.
11Fill the engine with new oil, replace the oil filter and fill the cooling system with new factory specified coolant. When you start the engine, be sure to let the engine idle with the heater on full blast. This is so the cooling system has a chance to bleed out any air bubbles. Some engines require a specific cooling system bleeding procedure, be sure to check for that.Awesome Quality ndk oil seals Exquisite Craftsmanship.
