Hi guys,

I did a lot of searching about smog pumps after finding that mine has died via the clutch seizing up.

So I see that the consensus on the smog pump is its useless after the car has warmed up. However, I gather from the responses to other posts that the rate of warmup is entirely dependent upon the smog pump injecting extra air into the combustion system.

My question is, could my long warm-up times be caused by a dead smog pump? It seems that I have to be driving long distances for the car to reach a temperature equilibrium, otherwise it drops down to 80 C or so and jumps at idle up to 90 C and then down again when in normal traffic or plain idling.

Thanks for your input,

-Troy

My smog pump is disconnected, and the car warms up within 5 minutes. Check you thermostat, and if you replace it make sure its a good quality.

The AIR system pumps air into the exhaust ports to rapidly heat the CAT before closed loop is attained to help control emmissions.
