04 Volvo v70 PZEV Model

As indicated by some of my prior post, I have had a dilemma or two with some parts, locating fuel filter etc. I discovered last night through some reading (which I should have done in the 1st place) my car is an 2.4l engine code 64. Which translates into the PZEV low emissions model. Apparently the PZEV was only sold in a handful of states in the northeast and California. My car was originally titled in CT, but didn't stay there long and went to GA early in its life, which is a good thing.

My manual states the t-belt service on the PZEV model is to be done at 150k, I just did mine at 77k, why would the interval be different? Also the tensioner for this car is different, which I discovered, but didn't really understand why until now. All of the PZEV (V70 04 anyway), models will have the steel gas tank and the fuel filter located inside. Which now explains why after much searching we couldn't find it.

I have not done much research on the PZEV deal, other than to clarify the emissions are lower than other models, and some say the fuel mileage will suffer due to this. Can anyone comment on this?

Anyhow, I just thought i'd throw this out here, so maybe if anyone has issues with parts it could be due to the slight difference in engine models.

Very interesting. I'm glad I live this side of the pond so we don't have these limited editions.

One thing I would query is the VIN 69. According to the maintenance chart VIN 39 and 64 are the PZEV vehicles with the very long t-belt change interval. The chart also says that the fuel filter is not replaceable.

I haven't done much research into the relationship between lower emissions and fuel consumption but I don't think that it will make a great difference.

Interesting indeed- we have an '04 V70 2.5T and as long as I've been involved with Volvo's, I've never heard of PZEV...this is a first for me.

My car is VIN 64, I had a "moment" this morning I suppose. I edited the original post to reflect this. Thanks for the reply and pointing this out.

Post or IM me your VIN.
I can run it through Volvo tomorrow and see what it says about it

I have done a little more research and the spec sheet shows that the 2.4 PZEV should be more economical with 22mpg in the city and 30mpg on the highway as opposed to 18/20 and 25/28 for the other engines.

I always take manufacturers' figures with a pound of salt but I have read other sources which give roughly the same figures.

I copied this from a quick search to see what all PZEV encompasses. This might explain the 150000 timing belt change question.

The good side of PZEZ..aside from extremely low emissions..is that the car makers are required to warrant performance for 15 years/150,000 miles...so that if "any emission-related part is found to be defective, the part will be repaired or replaced by car manufacturer for 15 years or 150,000 miles".

PZEV gets you larger catalysts and different cam timing. The fornt catalyst is closer to the cylinder head as this aids quicker warm up of catalyst. The emissions are also lowered by the steel tank as the plastic tanks are faintly permeable and some hydrocarbons escape through tank walls. The HP and torque are lower by a small amount.
I'm not sure if the injectors are different on the P1 engines but for many of them the injectors have more and smaller sprays holes for better atomization of the fuel.
The belt interval is longer due to the longer emissions. Same part number belt. If the belt was required within the emissions warranty period it would have to be at least partially covered.

A tech I know in Los Angeles says PZEV cars he smog checks usually have a negative reading on some of the exhaust gases. This means the cars exhaust is cleaner than the ambient air levels of those gases.

But yet they would not give a free belt change at 105-120k but hope for the best!
I dunno about that

This long interval Tbelt thing first came up with some red engines in 93-95 model years. They did at least change the belts when that stretched interval came up. The year the red engines got round toothed timing belts was the year the interval was stretched on B230FS with the pulse-air system. That was before the CA emissions was picked up by the 5 NE states so not many of those were seen around the country.
