Radiator Drain Valve

1989 K1500 350


Anyone have luck with this type of drain valve? On the side of the radiator you attach a
3/8 hose to drain it in a bucket.

After 2 hours I maybe had a half gallon, driving me crazy. Installing a new water pump
and the easiest part is turning out to be the most aggravating.

Thanks

Did you remove the radiator cap so the air could flow? Sometimes, it's easier to disconnect the bottom hose.

Yes I did. First time I was going to just change the hoses and it drained sorta good.. Found out it is the weep hole on the pump
so I tried again. Rather odd way of doing it, most people I've talked to have never seen that kind.

Can't help with the valve. But whenever I change a water pump I usually remove the lower rad. hose to drain since you are going to be removing it from the pump anyway. I always put new hoses on with any pump change since it's cheap insurance. YMMV

I've seen that type of drain before although they aren't common. As Ron said, just replace the hoses.

I finally put a big under-bed tote under it and pulled the hose.

Hardest part seemed to be putting the gaskets and pump on and starting the bolts.

So I cut the heads off a couple 6" bolts, slide the pump on and bolted it up. I'm sure
someone must of thought of this before but I'll take the credit.

Another trick is to strip some stranded wire. Loop it through the bolt & gasket holes. Start the bolts & remove the wire. It's easier than cutting the heads.

That's a trick older mechanics use on heavy stuff like transmission installs but work well for a lot of other things that are heavy or in difficult locations when you need a third hand. Save the bolts you may find another need for them some day, I have a bunch of various sizes of them. One other thing is to cut slots on the ends of them so you can use a screwdriver to unscrew them if needed. I also grind or file a bevel on the outer edge to keep parts from sometimes catching when sliding them on. Sure beats trying to hold a part and start a bolt, with the added benefit of not dropping and damaging things.

I seem to learn a new trick here all the time. Although I've never been a auto mechanic by trade, I have many many repairs, rebuilds etc in my early years & still tinkering, though I dont do any heavy stuff any more. Ahhh, them old 60's & 70's vehicles.... memories.

Thanks for mentioning that.

Good idea there, I did have to do a couple turns on one with pliers. Still no idea on that silly drain.

As a kid I had three different 58 Pontiacs, nice car. This 89 isn't bad, you can actually see all the spark plugs.


Thanks guys, the old girl is fixed.
