Pacific coast Datsun Posted January 15, 2016 Author Report Share Posted January 15, 2016 Slow going on the 620 lately but ive started on a new mod that will be multi purpose & fit the theme of the truck & best of all is basically costing me nothing but time...pix soon.. :yawn: 1 Quote Link to comment
Pacific coast Datsun Posted January 21, 2016 Author Report Share Posted January 21, 2016 Alrighty....new 180 thermostat installed the other day & next will be a new headlight if i can find one in this town i live in. & onto the newest mod ive been wanting to do this for awhile. I'm making a 3 piece bed cover using pallet wood & angle iron. Im sanding & staining the wood & I'll use some bare metal straps as support / looks. The other 2 sections will be hinged using small weldable hinges & the the wood is free from my job & im using an old box spring frame to support it all ! 2 Quote Link to comment

Pacific coast Datsun Posted January 24, 2016 Author Report Share Posted January 24, 2016 One mans trash is another mans treasure! Keep up the good work Mark! Correct on that sir & thanks. Got started on fabbing the rear frame today & i need 2 more pallets...... :frantics: 1 Quote Link to comment
Pacific coast Datsun Posted January 28, 2016 Author Report Share Posted January 28, 2016 Ok i made some progress on the rear section in the last few days... & I'm going to run the ST rims again due to old tire issues / dryrot / dont feel like swerving off into the desert when they decide to let go :w00t: 3 Quote Link to comment
Pacific coast Datsun Posted February 14, 2016 Author Report Share Posted February 14, 2016 More baby steps made on the bed cover. Im using some very ancient tire chains that i seperated to act as tabs & hold the wood slats in place with nuts & bolts... then i verified my temp gauge works by letting it idle for 20 minutes then on a short cruise..temp stayed @ 175 ish. & while on the street i took a few pix... 2 Quote Link to comment
Charlie69 Posted February 14, 2016 Report Share Posted February 14, 2016 Sweet Mark. I hope that this summer you can blast up the freeway at a steady cool temp. What degree thermostat did you install? I always run a 185 in Phoenix. Quote Link to comment

What degree thermostat did you install? I always run a 185 in Phoenix. Hell i just want to take it to work which is a 46 mile round trip. I went with a 180 & is there a diff between running premix & or straight anti freeze with diluted water added for our hott temps ? 1 Quote Link to comment
Charlie69 Posted February 14, 2016 Report Share Posted February 14, 2016 Just the price. I always buy the straight anti freeze. It is cheaper 1 gallon of straight anti-freeze makes 2 gallons of mix for around $14 including the cost of 1 gallon distilled water. 2 gallons of the mix cost around $18. I do not know if they use distilled water to mix. Most radiator manufacturers require distilled water for there warranties. Quote Link to comment
Charlie69 Posted February 14, 2016 Report Share Posted February 14, 2016 You are probably correct and I am running a 180 thermostat. Quote Link to comment
Pacific coast Datsun Posted February 14, 2016 Author Report Share Posted February 14, 2016 TY for the info on the anti freeze..I'll go with the straight & distilled water. 1 Quote Link to comment
Charlie69 Posted February 15, 2016 Report Share Posted February 15, 2016 A lot of people do not want to mix it so they buy the premixed. I save my empty antifreeze containers for mixing. After mixing i use a permanent felt marker and write 50/50 on the container. That is the ratio that should be mixed 50/50. 1 Quote Link to comment

What ive done in the past is to dump a entire gallon of straight anti freeze then top off with distilled water. I wonder what the capacity of the 620 cooling system is ? I want to ensure a 50-50 mix... 1 Quote Link to comment

Pacific coast Datsun Posted February 21, 2016 Author Report Share Posted February 21, 2016 Well i have a sad update..as i was driving the 620 to work yesterday the motor decided to give out. I heard what i believe to be a rod knocking @ 55 mph. Pulled over & discovered oil all over the DS of the block & no coolant in the radiator & the dipstick is reading zero ! Ive about lost all motivation to fix the truck AGAIN * waste time & $$$ on it. It will go into the garage & the boat will come out tomorrow & there itll sit until i decide what to do. May down the road sell it so i can get a daily driver...I give up the truck wins !! 1 Quote Link to comment
