Over heating, changed water pump, heater intake elbows, and thermostat, ran fine for a few days then stalled again. Smoke out of the exhaust and engine. Blown head gasket or UIM/LIM is my guess, but how...


Over heating can be cause from several things. Have you had a flow test done on the radiator as a number of cores may be blocked. Are the fins on the outside in good condition or are they flaking away. Have a pressure test done on the engine to determine if it is a gasket or cracked head. have a pressure test done on the cooling system to check for leaks Test the radiator cap for correct operation. Check the cooling fans are working and if a viscous fan hub check for proper operation. Carry out all the test first or you will be wasting money chasing the fault.

Can i remove one cylinder head and replace gasket?without doing both?and what is the torque sequence? This is on a pontiac 1976 400 ..grand prix


Yes, you can just do one head gasket, although I wouldn't recommend it.
If the head gasket has failed, it's usually because the engine has overheated. If you know that the engine has overheated, it would be best to do both heads.
When an engine overheats, the head warps a little. It doesn't take much to change the internal pressures on the gasket, and when the gasket area between the cylinders starts to lighten up a little, the gasket fails.
To do the job properly, take the head(s) to a qualified automotive machine shop and have the head resurfaced. Even a slightly warped head will be unable to keep a head gasket.
After a head has been resurfaced, it's relatively easy to put it back together.
NOTE!!
The machine shop will tell you the proper torque and torque sequence. Usually start from the center and work your way out evenly, going from side to side, and top to bottom, but get specific information for YOUR engine from the machine shop.
NEVER replace a head gasket without having the head resurfaced.

What is the life span of the timing chain? I removed the water pump and I thought I ask I also my plan to change the head gasket if I change the chain. Just so you know what happen I made a run form...


With proper maintenance, the chain should last 200,000 miles. As for the overheating, 225 is not overheating. Most cars these days that are equipped with electric fans, the fans don't turn on until 235. The most common problem with the cooling system on your car is the intake manifold gasket leaking at the corners. Sometimes this can appear to be a head gasket problem because coolant gets sucked into the intake ports of the engines. Head gaskets problems are rare because your engine has cast iron heads which can tolerate more heat than aluminum. As for the oil cooler lines, you just have to bend them a little and they should come out towards the front, under the bumper. If you decide to do the t'chain, I want to warn you that it's a bit complicated. There is a balance shaft above the camshaft, so there are actually two chains. One from the crank to the cam, one from the cam to the balance shaft.

OVERHEATING


Yes clutch fan could be bad,Radiator could need flushing,could have blown head gasket.To check clutch fan use a broom handle to see if fan will stop rotating when running at operating temperature.Not something you should do yourself as it takes practise to do without damaging fan if its still in good working order.If fan is not working very well this test shows it to be faulty very quickly as therse no resistance to the broom handle trying to stop it.To check if head gasket is an issue a TK Head test will show it up very quickly.Extremely accurate test.

1995 Nissan Maxima Over heating, no heat blowing, water not moving


Simple thing to test first would be to pressure check the radiator cap. Next would be to check for combustion gases in the radiator indicating a leaking head gasket.  It is an aluminum head and iron block engine and there is a possibility that antifreeze anti corrosionpackage runs out due to over age then fails due to too long in the engine it results in galvanic corrosion at the head gasket-commonly resulting in a failed head gasket.  There are other engines that are vastly more prone to this than the maxima engine.  If there is a leaking head gasket the gases could rise to the top of the system and block the water flow into the heater.  Listen for gurgling sound in the heater.

Car running hot


If the fan is working properly then you might want to check the INTAKE MANIFOLD for leaks or make sure the HEAD GASKET isn't blown. If the fan is NOT working properly, replace the fan and the pigtail that connects to it
