Change head gasket on 65 mustang 200


Drain antifreeze -DON"T POUR IT DOWN A STORM DRAIN - then remove valve cover, Remove exhaust from head assembly. On this engine the head is also the intake manifold - it's cast as a unit. Remove carb and remove heater hoses from carb base plate. Remove head bolts and discard. Break head loose from block - may have to smack it a time or two to break gasket loose. Get a buddy to help lift the head off the block - it's fairly heavy. Clean gasket surfaces on both head and block. Install new gasket onto block - pay attention to gasket orientation - it goes on only one way correctly. Reverse procedure to re-install - USE NEW HEAD BOLTS! Silly to try to save $20 bucks on bolts and ruin an engine.

How do you disassemble a head gasket for a 2004 toyota camery?


replacing a head gasket is a major repair and really should not be attempted if you dont have adequate knowledge and experince withthe process. That said, the head gasket is sandwiched between the cylinder head and the engine block. It requires removing everything from the top of the motor, then removing the cylinder head itself. The old gasket must be completely scraped off the head and the top of the block and any adhesive removed as well... The new gasket is placed on the top of the block in it correct place. Each side of the gasket must be covered with a thin coat of gasket compound. The place the head on top of the gasket, sandwiching it in between and replace the head bolts and torque them down to the required torque. Replace everything removed from top of motor in reverse order. Keep in mind that in replacing a head gasket, it is entirely possible that your problem may be the head itself instead of the gasket. While the head is off, take it to a machine shop and have them inspect it and if its needs it, have them repair it. Again . this is not a do it yourself job.

Would like to know how to determine if I need to replace my cylinder head or if it is the gaskets, I got white smoke coming from exahust and going through antifreeze


Hi, we are never sure if the problem is the gasket or a cracked head until the head is removed and pressure tested for a crack. Oftentimes, we remove the head carefully to preserve the gasket as much as possible so that we can inspect the gasket for leaks. If it is obvious that the gasket was leaking based on visual observation of breaks in the gasket, then we may skip the pressure test and just replace the gasket; however, there is no way of knowing until the head is off the engine.

HOW TO FIX A BLOWN HEAD GASKIT?


Buy a gasket kit for the upper end. Remove the valve cover intake and exhaust manifolds. Remove the head bolts. Remove head and clean up block from old gasket material. Take the head to a machinist and make sure that it is not warped. If it is warped either replace the head with a new one or have it machined true. Install new gasket and get torque specs with new head bolts and follow torque sequence using the correct torque specs. Clean exhaust, intake and valve cover of old gaskets. install new gaskets and torque according to specifications.

Leaking head gaskets in cooling system....reservoir is dry...no external leaks visible...


If you have leaking head gaskets in your cooling system you will have to remove the head gasket. You will need to remove the head bolt and remove the old head gaskets. Be sure to note the length of the head bolts in case some are long or short so you can replace them in the correct place. Fit in the new head gasket, replace the bolts, and torque to the factory specifications.

How to replace head gasket 1998 Lumina


Cylinder Head Removal & Installation 3.1L Engine To Remove:
NOTE: With some minor variations, this procedure can be used on both the left and right cylinder heads.
  1. Raise and safely support the vehicle.
  2. Drain the engine coolant and the engine oil. Lower the vehicle.
  3. Remove the upper and lower intake manifolds.
  4. Remove the rocker arms and pushrods.
  5. Remove the exhaust crossover pipe.
  6. Remove the engine mount strut bracket.
  7. If removing the left side (front) head, remove the dipstick tube.
  8. Tag for identification, then remove the spark plug wires.
  9. Remove the spark plugs.
  10. Remove the exhaust manifold using the procedures found in this section.
  11. Remove the eight cylinder head bolts, then remove the cylinder head. There are locator pins that align the head to the block. Pull upwards on the head to disengage the pins, then remove the cylinder head to a suitable work area.
  12. If the head is be overhauled, remove any remaining components such as the engine lift hook, the fuel line bracket bolts, the engine coolant temperature sensor, etc., as required.
Position a new gasket, install the head, then tighten the bolts in the sequence shown (3.1L engine shown) 93173g43.gif

To Install:
NOTE: If the head gasket failed, determine the cause. Gasket failure is caused by the following conditions: improper installation; overheating due to a failure in the electric cooling fan system or a leak in the cooling system; loose or warped cylinder head; missing, off location or not fully seated locator dowel pins; low torque on the cylinder head bolts; warped block surface; scratched or gouged gasket surfaces; excessive intake manifold torque and even cracked engine block tapped holes.
  1. Clean all parts well. Remove all foreign material to the bare metal. Do not use a motorized wire brush on any gasket sealing surface. It is good practice to use the proper size thread-cutting tap to clean the threaded bolt holes in the block. This helps assure an accurate torque reading.
  2. Place a new head gasket on the clean engine block deck surface. Many gaskets will have some sort of marking denoting TOP or THIS SIDE UP. Make sure the gasket sits flat and is not hung up on the locator dowel pins. Use no sealer on the head gasket.
  3. Carefully set the cylinder head in place, using care not to damage the gasket. Make certain that the head engages the locator dowel pins that properly position the head.
  4. The bolts should be very clean since dirt built-up on the bolt threads makes it difficult to get an accurate torque reading. These are 'torque to yield' bolts which stretch a small amount when tightened; new bolts are always recommended. On a used vehicle, especially a high-mileage vehicle, it may be difficult to determine if the heads have been removed before and how many cycles the bolts have been removed and tightened. New bolts should be part of any cylinder head service. Use GM Sealer #1052080, or equivalent, on the threads of the head bolts and install all eight bolts, finger-tight.
  5. With an accurate torque wrench, tighten the bolts gradually, in sequence, working from the center outwards. Final torque should be 33 ft. lbs. (45 Nm), plus an additional 90 degrees (1/4-turn). A torque angle meter is recommended.
  6. Install the remaining components in the reverse order of the removal process.
