I have been in the market for a large diesel truck for some time now. We currently have a 30FT 7400lb camper trailer that I tow with a Nissan Armada, and it was just not doing what I wanted. To not get too crazy and buy a new car, I thought I would play with a older Diesel first. Here are some things I have noticed after driving it about 300 miles. Nothing major, and a lot I have gotten answered from on this forum (thank you). Quick Note: I am far from being a mechanic, so most things I would have a pro look at for me with some direction from you owners.
1) The truck of course is the IDI (1989), it currently has 46000 miles on the odometer. Knowing these roll over, is there any think I can look for, or have someone look for to give me an indication of wear or motor life left? I do not mind investing in this truck, but I do understands motors can only go so long. I can tell you it purs like a diesel and does not smoke (white or black) never, ever, never. I heard thats good.
2) How long does your IDI take until it is "warm". By that, I mean if you were to crank it and know that you would in on/out of it most the day, how long would you let it run before getting in it and going? I let mine run a full day 10AM-9PM the other day because I have heard it is good to "run'em".
2B) If you were getting out of the truck for a period of time, what is the lenght of time you would keep it running vs shutting it off. Meaning, I run out to grab coffee (5 minutes), or I go inside to chat the wife (30 minutes). Is there a time in which leaving it running and turning it off/on equal out on wear and fuel?
3)The breaks a very squashy. The master cylinder was replace just before I bought it, and the previous owner said he believe it is a bad/new master cylinder. I am wondering if maybe he just did not bleed the break right? The break go basically to the floor, and will stop the truck, but you do not feel confident in them. Pumping the break will make the peddle stiffer, but breaks feel as if the work even less then. The peddle stiffness is gone after about 5 minutes of driving if you do pump them.
4)Glow Plugs- What is your practice? I have heard to let the "Wait" light do its things, and wait some more to be safe. I have also heard once the truck has been ran - don't wait at all? I am patienct, and wait for the light every time! Also, I was told to plug it in if I plan to crank it in sub freezing temps.
5)What RPM do you run on the highway? At 70MPH. I am running about 3k. I can run 80, but am getting near yellow on tac. Sound normal? I do have the automatic, and I believe they are 3 speeds?
6) I know towing weight is all over- but with this truck, what is a camper weight that it will easily pull at highway (65-70) speeds. I know hills are a bummer. I currently have a bumper pull at 7500lbs, and am thinking about getting a larger Goose neck.
7) The truck seems to be stock all over the motor. Which I like. I have read the things to do to get a little more power, but will "more power" be hard for this "who knows how old" motor"
8) The truck needs a passenger rear fender. I am having difficulty locating one. Any suggestions?
Thanks for any help. I have attached a picture of it. The inside feels and smells new. It is the XLT model, which I believe was decent in 1989.
