Hey all, feeling a bit anxious about my build at this point. Just completed a lot of interior work recently and drove it for the first time in a few months yesterday.
She’s always been a bit slow, just about normal for a mid-size that’s 31 years old. (65 on interstate, climbs steep grades at about 35 or so)
But yesterday it was having noticeably more trouble than usual. I happen to live on a mountain at 1,800 ft elevation. Normally it makes it up a little slow, but it gets there. This time it started overheating about halfway up the mountain and was doing maybe 25 MPH tops. I had to stop twice to prevent it from overheating.
What should be on the checklist for things to look at mechanically? It had been sitting for about 3 months after I drove it last, starting it up every week or so. Cooling system seems healthy/clean. The only thing I could think of that’s really changed is that I’ve added a 40 gallon water tank (currently empty) and a rear-mount storage box on the back trailer hitch. Shouldn’t be more than about 600 lbs. Could that have made much of a difference?
If nothing changes in the short-term, what are some longer term solutions to this? Ie rear end upgrades, engine upgrades. The current engine is the DD 8.2L fuel pincher. Not sure of what transmission it has.
I’m just getting really worried that my last 12+ months of work will go to waste on a brick. I wanna talk about short and long term solutions. Any input or ideas would be greatly appreciated. Thanks for reading
