Replying to: tsurnick (Sep 29, 2008 2:38 pm) Did you get all your surfaces clean? Are you sure you have not had a gasket slip on reassembly? I think one of these two things is likely the issue. Try squirting carb cleaner in all ares of the replaced gaskets, and see if idle increases. I do believe your repair was not properly carried out most likely.

A series of two sets of five flashes in a row, is 55. That should always be the only code, unless the battery was recently disconnected and you will get a one two flash, which is 12, and then fifty five. Any code flashed before 55 code is a fault code.

| I just got everything else repaired and now the LHS started overheating today. One thing i dont like about this particular vehicle is the cooling system. it has one of those self contained radiators that doesnt have a cap on top of it. the overflow tank is near the firewall on the passenger side. I have recently replaced the thermostat. ( I had to take it off when I replaced the intake manifold gaskets). what should i check first on the cooling system. We actually changed the fluid about 3 months ago. What is a good way to tell if the radiator is clogged? | |

Replying to: tsurnick (Oct 14, 2008 6:17 pm) The first thing that comes to mind is air locks in the cooling system. When the radiator is drained AND filled the heater must be full on. If it wasn't then drain and start again. Also as it first warms up after filling, bleed off the air by opening the air release valve on top of the thermostat housing. Remember the heat must be switched full on with the engine running before draining, as it needs the electrics up and vacuum to set the heater full on. Talking of the thermostat, make sure it is correctly oriented. It is eccentric, so make sure it not only is the right way round, but that none of the struts is impeding flow. Most modern thermostats are very sensitive to correct orientation. The third and worst possibility is that you have leak of coolant into the manifold due to a gasket leak around a waterway on the intake manifold. Did you put a bead of blue RTV sealant around the waterways on the intake manifold, as specified in the repair manual? If you are leaking water and replacing it with air, then you should see a white sweet smelling exhaust, especially on first starting up. Also a plug or two will show evidence of water present during combustion. Those are my thoughts on things to check. |

| Is the original exhaust pipe spliced before or at the wye ? | |
so i got a working heater control and now it wont blow hot air?? im told that you have to take the entire dash out to access any of the components that could be causing this, i.e the actuator that opens and closes the door to allow hot air to come through. does anyone know if any of this stuff can be accessed without taking the dash out?

Replying to: nbelt (Nov 12, 2008 8:08 am) As you select modes does air blow from the correct locations? Have you done any work on the cooling system, or drained it for any reason? The heating cooling system is complicated, and you need an accurate diagnosis before pulling ANYTHING apart. You can get fault codes from the ATC . Have the engine idling and the temperature set to 75 degrees. Hold down the top two left buttons and the top farthest right, (floor, mix and defrost). Hold them down simultaneously until the display section blinks, then release them at the same time. The display will blink for a while and then show any double digit trouble codes from 23 to 36. The display can only display one code at once. To move to the next code, press and release the lower left button (panel). Continue until all fault codes are displayed. Record them and post back here. |
