| | | Improve performance/MPG - first service | Joined: May 2012 Posts: 251 enthusiast | OP enthusiast Joined: May 2012 Posts: 251 | I got the van a month or so ago now. The first area im looking to improve is the overall performance of the engine. MPG isn't the best and with higher petrol cost here would like this to go up in anyway.
Going to give the van a service, and as i know nothing about its service history other than it was owned but the US army up until 07 then privately and has 145,000 on it, so hoping it had a goods service record but assuming the worst. so planning on the following
1) Oil change 2) Performance air filter 3) Fuel filter (don't know if its ever been changed) 4) Oxygen sensor (for the money i may as well change it it too)
5) in the next couple of months ill be getting a cat back duel performance exhaust, i may get custom headers while the shop is doing this depending on the price.
i would really appreciate any feedback from you guys on the above and any additions or improvements.
thanks
phil

do a search on your vin # it may yield some information...

It seems obvious you plan on keeping this vehicle.
Since I am spending your money:
Tranny fluid. get some quality synthetic in there and possible a deeper pan with a drain plug. Change the filter, and possibly add an magnetic inline filter on the cooler line.
Add an additional tranny cooler.
Diff fluid. Quality synthetic again.
Do you only have one O2 sensor? Some newer vehicles have 4
Cap wires and plugs.
Turkey baster the power steering fluid to refresh.
Turkey baster brake fluid from resevoir, refill then rebleed all brakes
Once you got all these bases covered and know your tranny and diff are healthy, only then would I'd consider power upgrades. | | | Re: Improve performance/MPG - first service | Joined: May 2012 Posts: 251 enthusiast | OP enthusiast Joined: May 2012 Posts: 251 | Yes ill be keeping this like my defender.
tans and diff will be done at the same time, is there a filter for the tran?
o2 sensors ill check, i thought it was just one in front of the cat? but still finding my feet.
cap and wires could do..
brakes were done before i got it so will prob leave that until i have to, steering is fine.

Usually the filter comes with a pan gasket too. I think you just have the single oxygen sensor. Warning!!--Custom headers are expensive!! Very labor intensive.
When Chris Farley talked about living in a van down by the river, did anybody else think that wasn't such a bad idea?

Very labor intensive. ok ill thrown in a trans filter & gasket too. Just getting a quote for the headers, while getting a quote for the exhaust work, ill be keeping the van so in the long run may be better doing it all in the one as shipping headers over from US costs as much as the headers themselves. and got an e-mail back from headdmen saying they have no products that fit myvan???
