 |
|
| I recently failed emission and so I replaced some parts and gave the van the good old tune up. I replaced the cat, 02 sensor, distributor, plugs, ignition wires, air filter. I took it for a spin around the block and the temp got up around 3/4 on the gauge. This is hotter than usual. Would anything I replaced cause it to run hot. I set the timing with a gun at 3k rpm and set it with the 0 mark with the gun set to 35. The van is now idling lower and running smoother than it used to. Ideas? |

You lower idle and hotter coolant suggest retarded timing. Try it at 40 degrees using the same gun,method and reference point for consistency sake.

If I wanted to retard the timing wouldn't i set it to 30 degrees. Wouldn't 40 degrees advance it? |

Retarded timing can cause hot runing especilly around town. I'm suggesting that you try advancing it 5 degrees from 35 to about 40 and see how it is. If you go too far, you'll get pre-igniton (spark knock) and run hot under load. Older engines can develop a taste for some additional advance. Experiment.

| It would be nice to know which of the three gasoline engines VW used in the rigs for the US market you have. They do not all time the same. |
