1996 302 Engine Cooling Question?
Hey all, it's a '96 F150 Northland that I'm gonna replace all the rubber for the cooling and I've got two questions...
1) What size are the heater hoses?
2) The drain plug in the engine block, I only find one on the drivers side. Is there another on the passenger side? My neighbor has an older 302 sitting on his garage floor and it has two plugs in the block, one on each side of the motor. I only find one on mine. Is this right?
And to be sure, it takes a 1/4 inch allen as far as I can tell, right???

Yeah, I went and got all my hoses last night so I'm set up on that part, except I just discovered that one of the heater hoses out of the water pump has a pressed fitting, O'reilly's didn't seem to have anything like that. Is that an OEM part only? I just know if I leave it and change all the others it'd pop on me in the future.
I can't get the plug out with just an allen wrench, I even put the end of a big crecent wrench on it and it wouldn't budge. I guess I need to go buy a set of allen sockets so I can put a ratchet or breaker bar on it.
I looked again and I can only locate one plug on the drivers side and none on the passengers side of the block.

The metal tee for the throttle body 3/8' line tap can be reused if not rusted out, by taking the metal crimp ring and cutting it off to allow the hose section to be replaced - just use a hose clamp on it at both ends.
Be careful with the plug to make sure it doesn't get rounded - an allen plug socket will probably get it.

Cause I wanna get all the dirty water out faster. It's taking me forever to to get all the ugly stuff out by cycling it from the radiator to the block and heater (starting motor and warming it up and dumping out what I can from the radiator). I cycled it at least 5 times last night and everythings still coming out dirty.
The antifreeze that was in it looked like it was the orginal stuff from when the pickup was new. Yes, it was pretty bad. I'm just trying to make it better, peace of mind, I guess.
Maybe I'm doing it wrong but I know no other way.

I used the "radiator cap with a garden hose hookup" and removed the heater hoses @ the engine so i could put them back on and off or cover them with my finger to manipulate the water flow. As long as you have full flow from the garden hose you can run or not run the engine. Unseal your water system before applying water pressure. The 40-60psi from the hose is too much.

That's the answer I was looking for!

You can go to any parts store,i.e. Advanced or Autozone and buy a Prestone flush and fill kit for less than $10 that will allow you to flush everything. It has the fittings and tees necessary to tap into the hoses and you use the garden hose method. I've had one on all my vehicles for several years. Makes it easy to flush every year.

Since your engine is that cruddy, I wopuld use prestone radiator flush concentrate, it comes in about a pint size jug. Basically you fill the system with wate, pour in the little jug, bring it up to temp for 20 minutes (i think), and then reflush with water. It gets out alot more crap than water alone.

ps - the prestone flush n fill kit is $2.99 at my Walmart and I highly recomment it too.
