Default New from Phoenix Arizona

Hi. I'm new here and anticipate learning a lot. I just purchased a 1985 D24T model 740 GLE 4 door sedan from Bill Stewart who had it advertized for sale on the forum. I'm very pleased with this car, needs a few things, but runs well and I'm getting a little better than 25 MPG which I think is great .I do have diesel knowledge as my truck is a 1997 Ford F-250 crew cab 4X4 with a 7.3 liter International V8 turbo diesel. I also drove big rigs for a few years. Looking forward to learning about these small engines. Later. Allen.

Congrats on the new rig!

25 mpg sounds about right, assuming you do mostly in-town driving. Mine have always averaged around 27 overall, with a mix of city and highway... they can do better than 30 with highway use at moderate speeds. Is yours an automatic or stick?

As you've probably already seen from looking around here a bit, these are good engines and last a long time providing good performance and economy, but there are a few key things to keep on top of to keep them out of trouble: they require good synthetic oil, the timing belts need to be replaced correctly and on schedule, and cooling system upkeep is important since they do not tolerate overheating. Located where you are in AZ, cooling system performance may be tested more than usual so a thorough check-up on those parts may be a good starting point, especially before the summer months start if you're planning to drive it much then.

We will look forward to hearing more as you get to know it better! Welcome to the forum.

This car had new timing belts and cooling system when I purchased it. Maybe 1000 miles on each. I use the same Xerex G-05 coolant that I use in my International diesel in my F-250 pickup. It had a new oil change and filter when I bought it but I don't know what oil he used. I will do a Mobil 1 change soon. This is such a low mileage car, I really plan on driving it for MANY years. Thanks for the welcome. I'm enjoying the forum.

Sounds like you got a good one.

If the timing belts were recently changed, you may want to do a little bit of looking into who did them and ask about their methods. Depending on how it was done, you may want to double-check the torque on the crank dampener bolt, which requires the use of a special tool that most folks don't have... The required torque on this bolt is around 350#, hard to achieve without the tool, and if not torqued to spec it will allow the timing to slip and crash the valves. It is a fairly common occurrence for a timing belt to get changed and the engine running well afterwards, but then have a disaster come shortly after as a result of insufficient torque on this one bolt. This has even happened to a few folks on here in the relatively recent past.

Not trying to spread fear around, just recommending checking up on this for the sake of peace of mind, since it's easy to do. If you find out that the tool wasn't used, or if you cannot get the info to be sure, you'll want to check the torque on it yourself, which only takes about 15 minutes (have to pull off the fan and shroud for access, 4 nuts and 2 screws). You can borrow the required tools from folks on here for free if needed.

Enjoy!

The work was done at Southwest Diesel here in Phoenix. They have a stellar reputation and work ONLY on diesel engines. Nice to have a shop of this caliber nearby.

Sounds like the right folks to have wrenching on it.

Even so, can't hurt to ask them how they torqued that bolt and if they have the tool... even if they know exactly what they are doing and did an expert job with everything else, if they didn't have the tool there's no guarantee they got the torque on that bolt right. Given that it sounds like you've got a car that's in great shape and had a lot of good work recently done, would be a bummer to risk letting this be a concern... cheap insurance to check it. Either you'll find it's already fine and you'll have peace of mind for having confirmed it, or you'll find that it needed adjustment and you'll prevent an avoidable failure.

Here's one of the things that's guaranteed to happen if that bolt isn't tight enough...
