newdatsunowner720 Posted August 27, 2014 Report Share Posted August 27, 2014 Hey guys, I'm new owner of an 84 model 720 pickup. I have some few questions to ask you guys as a forum. I'm new to any kind of mechanic work like total newbie but I'm mechanically inclined and willing to learn new things on my truck. Okay here's the situation ... I bought my truck and the first day igot it it broke down on my home , luckily wife was following me and we got it towed back home. I traced the cranking problem back to the fuel pump and replaced it. Its running fine now and I haven't drove it any long distance but wanting to use it as a daily commuter (not my only car). The other day when i was looking over the trucks engine I saw that the coolant was low and it was all rusted looking and nasty. I was wondering how to get this out of the system and put New coolant in the system. Also, with engine running fine right now that's know of is there anything I should do to make it run better or any kind of PM that I could do ? also anyone know where I could get a New cheap coolant resovoir for my truck as the one In mine has a whole in it hence that's why all the coolant is nasty. thanks guys Quote Link to comment
Justin Berni Posted August 27, 2014 Report Share Posted August 27, 2014 Pick n pull should be fine for that haha. I just pull the lower radiator house to drain coolent. Re torque your head bolts, z24's, which I think is what you have if you've got a 84, are known for blowing head gaskets every 100,000 miles. I'll wait for someone smarter than me to give you good instructions on how to do that tho. Quote Link to comment
newdatsunowner720 Posted August 27, 2014 Author Report Share Posted August 27, 2014 Yes I have the z24 and like I said I'm new to this project car thing so I'm learning as I go. The truck has 134k on it. 1 Quote Link to comment
Justin Berni Posted August 27, 2014 Report Share Posted August 27, 2014 Do you have a repair manual? I bought one for like $20 on amazon, it comes in handy. Quote Link to comment

newdatsunowner720 Posted August 27, 2014 Author Report Share Posted August 27, 2014 What kind of manual is it? Quote Link to comment
Justin Berni Posted August 28, 2014 Report Share Posted August 28, 2014 http://www.amazon.com/gp/aw/d/1563924102/ref=mp_s_a_1_2?qid=1409183894&sr=8-2&pi=SY200_QL40 When you have $25 to spare this is a good investment. Quote Link to comment
newdatsunowner720 Posted August 28, 2014 Author Report Share Posted August 28, 2014 Thanks for the link, I'll take any kind of help I can get . I really appreciate it! You know where I could get a cheap coolant reservoir for my truck Quote Link to comment
Justin Berni Posted August 28, 2014 Report Share Posted August 28, 2014 Personally I'd just go to a wrecking yard and find one. But rock auto might have one. Quote Link to comment
datzenmike Posted August 28, 2014 Report Share Posted August 28, 2014 A better one is the '84 Nissan FSM factory service manual. It's the bible for your year of truck. E-Bay? The coolant is brown because the previous owner did not look after it. All cooling systems need an anti freese coolant with rust inhibitors. Water added should be distilled or rain water. The block, the heater core and the rad all need to be flushed out to get rid of the rust and scale. Quote Link to comment
newdatsunowner720 Posted August 28, 2014 Author Report Share Posted August 28, 2014 After I flush out the system. What is calls recommended actions on making this a better longer lasting truck. I wanna be able to trust this truck on about a 8 mile round trip knew or twice a week do y'all think that's possible with this truck having 134k on it. I mean I am kinda gunshy of it right now cause when I first drove it back home it broke down on me. Therefore I replaced the fuel pump and it has fixed it's cranking problems. I have drove it around town and no problems right now but idk about a long distance drive. Also what are t be symptoms. Of overheating without relying on the gauge cluster. Thanks guys for all the advice I'm very thankful of it! Quote Link to comment

that-son Posted August 28, 2014 Report Share Posted August 28, 2014 change ALL fluids, filters, plugs, wires, hoses (heating/cooling) all rubber hoses you see in there, brake lines, tune up... when you get the manual read/skim it cover to cover and you'll get a better idea of what needs to be done! now where are the pictures?

datzenmike Posted August 28, 2014 Report Share Posted August 28, 2014 The Z24 has a history of blowing the head gasket at about 100K intervals. The factory preventative is to re-torque the head at every tune up, or at least once a year. The procedure is to do this on a cold engine, loosen one head bolt and tighten to 60 ft lbs, move to the next bolt. You can do this in any order you like, just remember one bolt at a time. Don't be surprised if some of the bolts already feel loose. Quote Link to comment

Jeremiah720 Posted August 29, 2014 Report Share Posted August 29, 2014 fairly clean under there :thumbup: Quote Link to comment
Charlie69 Posted August 29, 2014 Report Share Posted August 29, 2014 Mike is correct get the 1984 Nissan Factory Service Manual if you are going to buy one. Much better than the after market manuals that cover multiple years and models. Search ebay for one. Quote Link to comment
