Looking for procedures to remove and replace vacuum pump for "02 F250 Diesel. Heated and cooled air only going to the defroster outlet at the winshield. Dealer says its the vacuum pump; I can get the pump from Autozone; autozone says its belt driven;Haynes manual doesn't show it as being belt driven. Dealer offer 12 month 12000 mile warranty on the replacement vacuum pump. Autozone offers lifetime warranty on the pump, thus I figured I might as well change it myself. Has anyone changed this part? Thanks in advance for your help.

 

the pump is belt driven it is on the passengers side fornt of the engine. once you have the new part it will be obvious.

 

This is strange; I looked on the right fender wall and I see what the book describes as the vacuum pump. I called several parts stores; they said its belt driven. I spoke to a Ford Parts supplier they said the later models (appx post '99) have electrically driven vacuum pumps. I looke on the schematic for the drive belts; it doesn't show a vacuum pump as part of the sepentine belt run. Please advise.

 

2002 (99-up) are electric, not belt.

before replacing the pump, check to see if that is the problem. if you have a bad hose to the heater box, putting a new pump on will only make you mad as heck and quite a few dollars poorer.

 

Here is the original problem that started months ago. While driving with the AC, I heard a fluterring sound on the dash. A few days later, the turn signals, heated seats, and overhead console all went out, additonally the airflow was stuck in the defrost position at the windshield. I found a fuse burnt out, which I initally overlooked but a Ford Truck Enthusiats in this forum insisted it must be a fuse. Of course fuses blow to protect further damage. Once my turn signals, heated seats, and console were working again, I didn't bother with the airflow problem until now.

I took "the Beast" to the dealer to troubleshoot why the airflow was stuck at the defrost position;they said it was the vacuum pump. Here is the big kicker. They said it would be $353.00 to change the vacuum pump. I told them to hold off; paid $74 diagnosis fee and left; spent the day trying to figure out whether the pump was electric or belt driven. Ultimately, I went to another dealer and bought the electrically driven vacuum pump for $129; removed and replaced the old one using a #10 mm wrench while standing with the hood open next to front passenger tire; and the whole job took SEVEN minutes. Op check good! The dealer wanted to charge me $150 labor for a 7-minute job. UNBELIEVABLE.

 

Thread moved to the 99-03 7.3 forum.
Good news on the repair.

 

I just saw your post. Had to do mine in June, dealer wanted over $200 for the pump, had it shipped to my door for less than $130. And you are correct less than a 10 min job.

 

Sounds Like You Got It.
I Was Going To Offer Help As I Have Changed My Pump Out As Well.
Parts Store Kept Telling Me That Mine Was Belt Driven Too But Ended Up Buying The New Vacuum Pump From The Dealer. Your Right ..... It Was Very Easy To Put On. No Way I Would Let A Dealership Do Any Work On My Truck Ulesss I Just Absolutly Have To.

 

I agree. I plan to stay far away from dealerships. They are good for diagnosing problems and I'm willing to pay that fee. Thanks to all for your input. This is a great forum.
