youll likely be a lil strong on the coolant but no harm. 50/50 now, drain 2 would yield adding 2 pre mix back or 1 H20 1 coolant.

Still way overthinking this one. Read the posts on 80 tech too. Go ahead and pull drain block, and really with system open would be a great time to flush heater core as well. I know you were trying to be quick and simple.... but day 3 now and your right there so might as well knock it all out at once.

Block drain is easy.... lift the front driver wheel skirt and look straight at block behind the shock tower. its the bolt in the block not bolting anything on.

Personally i have always drained the block and rad completely, filled with water, ran to temp, drained and filled both again. repeat.
You can leave just water in there for a day at a time to make it easier to fit drainings into life's schedule. Shoot, Ill usually dump and fill twice and then run a hose into the top radiator and let truck warm up and alternate draining from petcock and block drain letting the water pump help flush all the junk out. Button up and fill the block from upper rad hose, then fill the rad. burp system and monitor for next few days.


Izzy's writeup makes it almost foolproof and I added a pic or two there. Not all of this is needed but one way to do it.

If I read correctly he was running the engine for an hour and adding water as it drained from the radiator. That leaves coolant % close to zero.

Gotcha. Didnt catch that part between the diff threads. Makes sense; carry on.

@mtweller Dozer got some attention!! Moved the driver's seat towards the center and as far back as we could. It's all about driver comfort

Correct. I will see if I can drain the block too. I ran it for an hour with both heaters full blast to the point my Ultra Gauge said it was too hot for the Ultragauge to operate...lol.

As usual, JC gave up his Sunday for a fellow ONSC'r. Can't thank you enough - I can now drive Dozer without being int he fetal position. Feels crappy to not have my own shop anymore, and rely on others' help, but @GLTHFJ60 knows how to make you feel ok about it.

After driving home last night, I think I'm going to put some spacers in the rear to raise it a bit, distance is NICE, but feels like a bit of a low rider even with the seat back reclined to a minimum.

Thanks....tons of good info. I can see to the block from my wheel well but couldn't pinpoint the block bolt. At this point I just want to get it filled with coolant and be done. Block drain will be for the next time.

or maybe a new steering wheel?

We could always re-make the rear mounts to get it up higher without spacers!! Wouldn't be a bad thing for the bracing we talked about anyway.

Wish i could get another inch or two outta mine as well.....theres a bit of interference with that whole cab thing :/

^^^THIS has to be about the best (and most taken for granted) mod I've ever done to the 40. Every time I drool over a 45 and "wish I could" the end result is I just don't fit and there is no way (short of major body mod) to move the seat back.

Nice work!

There's a fix for that too my man, little bit more work though

 

[sleepycruiser]

Looking for the block drain for the coolant.........is that it in the first pic??

 

[jfz80]

second pic (and first) look to be the block drain

 

[sleepycruiser]

Thanks, Now just to reach it.

24" extension through the fender and you're there.
