Mike8199 Posted January 21, 2017 Report Share Posted January 21, 2017 Im running my truck right now with no coolant res. Works fine, but im just running water. Any ideas on custom resivors? I cant find any cheap oem fit ones. Or will other nissan vehicle resivors fit the 720? Quote Link to comment
Lockleaf Posted January 21, 2017 Report Share Posted January 21, 2017 I have a spare one of those as well... But you can use anything you like that holds water. Often used are cool looking alcohol bottles. Universal versions can be found on Amazon or eBay. Quote Link to comment
datzenmike Posted January 21, 2017 Report Share Posted January 21, 2017 It's a coolant recovery bottle. Over pressurization from heat soak after shutting off on hot days, burps out and is saved. When the engine cools, the special rad cap allows the coolant to siphon back in keeping the rad full. I was constantly topping up my rad before buying the special cap that is on later Datsuns and Nissans. I just used a plastic water bottle with a hole in the top for the over flow hose. Now Maybe a cup in a year. Anything will work for the coolant recovery bottle. Keep if half filled and the hose down to the bottom and well submerged. Be sure to use anti freeze mix in it. 1 Quote Link to comment
flatcat19 Posted January 21, 2017 Report Share Posted January 21, 2017 Why not just get one that goes to your truck. And why straight water? Iron block...um... Quote Link to comment

datzenmike Posted January 21, 2017 Report Share Posted January 21, 2017 Gato's right, never just water. Buy come distilled water (that's free of dissolved minerals) and a quality antifreeze coolant. This will avoid crusty deposits in your rad and rust formation in the block. Another thing that Z24 engines need is to have the head bolts re torqued at least once a year. Z24s are prone to blowing the head gaskets at 100K intervals. 1 Quote Link to comment
KoHeartsGPA Posted January 21, 2017 Report Share Posted January 21, 2017 And pray none of those head bolts snap :no: Quote Link to comment
Lockleaf Posted January 21, 2017 Report Share Posted January 21, 2017 They aren't torque to yield so breaking them is unlikely. Quote Link to comment
paradime Posted January 21, 2017 Report Share Posted January 21, 2017 True all that, antifreeze is only one job the coolant does to protect the cooling system. Here's what I did. Cheep oil catch can from Enjuku $45 and re-plumbed it to work as a coolant res 2 Quote Link to comment
datzenmike Posted January 22, 2017 Report Share Posted January 22, 2017 They aren't torque to yield so breaking them is unlikely. Agreed. Cold engine is essential. Loosen ONE bolt and then tighten to 60 ft lbs. Go to next bolt, loosen and torque to 60. Two things... only one bolt at a time loose at any time,... and any order you like. Quote Link to comment
KoHeartsGPA Posted January 22, 2017 Report Share Posted January 22, 2017 They aren't torque to yield so breaking them is unlikely. Buddy of mine and I broke all but 2 just taking them off to replace the head gasket...happened on two z24 engines...they do break....and both motors were cold....we got them knowing the head gasket on both were blown :( Quote Link to comment
Lockleaf Posted January 22, 2017 Report Share Posted January 22, 2017 Rust issues from blown head? I've taken the heads off a few z24s and done the retorque on a couple others without issue. That is interesting that you've had multiple engines give you head bolt issues. I wonder what the cause was? 1 Quote Link to comment
KoHeartsGPA Posted January 22, 2017 Report Share Posted January 22, 2017 Ya...PO on both motors didn't know the concept of coolant, I don't understand why 720 owners don't use coolant.....seems like 9 out of 10 I looked at have orange water.....dafuq.....idiots. Quote Link to comment
paradime Posted January 22, 2017 Report Share Posted January 22, 2017 So now 9 out of 10 720 owner are idiots? dafuq 1 Quote Link to comment
KoHeartsGPA Posted January 23, 2017 Report Share Posted January 23, 2017 Saw two more today, both had orange water....ugh... Quote Link to comment
Mike8199 Posted January 23, 2017 Author Report Share Posted January 23, 2017 Im panning on using coolant, im just using water to flush the block and such, will drain and add coolant when i get a res. (Fresh motor). Quote Link to comment
KoHeartsGPA Posted January 23, 2017 Report Share Posted January 23, 2017 :no: Every minute of water inside the cast iron block is rust food, what is wrong with you 720 owners????, seriously!, drain it and put 50/50 at very least, flushing is done right away, not days. Quote Link to comment
datzenmike Posted January 23, 2017 Report Share Posted January 23, 2017 The vast majority of 720 owners are 3rd, 4th 5th ... owners. They bought them cheap and a/ are used to low maintenance newer vehicles b/ don't want to spend money on something they didn't pay much for c/ are stuck with a POs decision on maintenance neglect. This is not at all 'always the case'. If you are here, you probably have some interest in your truck and want what's best for it. It's always better to have a clean system with distilled water and antifreeze coolant in it. Always run a coolant recovery system so you don't have to top it up with whatever water is around and dilute your antifreeze. 1 Quote Link to comment
KoHeartsGPA Posted January 23, 2017 Report Share Posted January 23, 2017 I get irritated quickly by poor maintenance....it's not hard and you benefit from it....extend the vehicle's life and decrease breakdown chances...win, win. Quote Link to comment
datzenmike Posted January 23, 2017 Report Share Posted January 23, 2017 Agreed. It's a shame to see it. Quote Link to comment
