SOURCE: Olds silhouette heater blows cold air

as long as the engine temperature is normal, i would suspect a clogged heater core, the dex-cool antifreeze is notorious for building up deposits in cooling system. have heater core flushed first to see if it makes any difference

SOURCE: lower intake manifold gasket leaking 02 Olds Silhouette

This is basicly a very time consuming job rather than a physically hard one to complete. In order to replace the gasket you must remove the intake plenum,throttle body, and misc. vacuum hoses. The wiring harness connections must also be disconnected. Finally the intake manifold is exposed. The bolts holding the manifold to the block are removed exposing the leaking gasket. After removing the push rods and placing them in the correct order to be replaced the gasket and sealants can be removed. Finally replace everything in reverse order. Be sure to consult a GM manual for correct bolt torch specs. The correct specs for the manifold bolts usually come with the gasket. Make sure to change your oil a few times after this job in case any coolant entered the block. Also,change the thermostat and the oil seal on the distributor half shaft cap while you have everything off. Good Luck

SOURCE: how do I reset the service engine soon light

A diagnostic scanner that reads OBD1 (the system by which your vehicle processes trouble codes) will be required, many parts stores do this a s a free service. Check with them to see if they charge. Remember though, when they read the car and turn the light off that in order for the light to stay off, the problem must be fixed. Even if it was a one time fluke of a problem, get the code that their scanner gives them so that you know what the issue is.

I had to bypass my heater core. I snaked a hose from the input pipe around the motor and tied back in at the thermostat BYPASS HOUSING. I started with a 5/8 hose piece to a 3/4 elbow back to a 5/8 hose...


Was the heater core leaking? Have you checked your thermostat? By passing a leaking core should stop a running hot problem if that was your only leak. Does your cooling fan come on? Has the car been run extremely hot?

I have a 1997 olds siloutte that is overheating


clean and degreese the engine from the top to the bottom. fill the radiator and start the van let it idle for at least 20 min and look for a leak. if no leak present look at the tail pipe smoke. if smoke is white you have a bad head gasket. Also check oil to see if it"s milky

1 drain the coolant
2 remove the air snorkle fron the trottle body to the air box
3 disconnect the heater bypass pipe that runs across the front valve cover
there is a 8mm bolt and a 13mm nut at the trottle body remove the hose at the front and the 2 at the trottle body
4 disconnect the throttle cabe and cruise control if equiped remove the wiring the TPS IAC then remove the throttle body bolts 13mm CAREFULLY REMOVE THE TROTTLE BODY AND THE GASKET SHOULD BE OK TO REUSE if it tears replace it
5 now you have acess to the thermostat remove the rad hose
6 there are 2 13mm bolts the top one remove all the way the bottom one has a slotted hole remove about 80%
remove the thermostat housing
7 replace the thermostat
8 REASSEMBLE IN REV.ORDER and the O RING SEALS lube with a silicone grease
9 after the vehicle is all assembled LOOSEN AIR BLEED SCREW ON THE BYPASS PIPE
10 refill cooling system till coolant FLOWS OUT THE AIR BLEED IN A STREAM CLOSE THE AIR BLEED

Wher is the thermostat located on a 2000 olds silhouette?


Follow the large radiator inlet hose from the radiator, to the thermostat housing. Once the housing is located, simply remove the housing to expose the thermostat. It may be necessary to remove the air cleaner and duct assembly, and the crossover exhaust pipe, as well.

What is the part the goes on the hose for the splitters that connects to the three hoses for the cooling system on a 2001 Ford Focus ZTS?


I assume that you are talking about the Thermostat Housing. (The plastic thing where the upper radiator hose mounts, along with a heater hose and a bypass hose.) These are bad about cracking and leaking. Dorman makes a replacement assembly for this. The kit comes with the entire assembly, including the thermostat. It should be available at most any parts store.
