Radiator Flush Kit

Radiator Flush Kit

Postby bombeam2004 [OP] » August 17th 2010, 3:03am

The two metal nipples that come from the heater core on the passenger side of my 2004 Safari have hoses that route to the engine. Can anyone tell me which one to cut into for placing the "T" for that radiator flush kit? The upper hose is smaller, and appears to be coming from a fitting on the top of the water pump. The lower and larger hose goes back on the passenger side of the engine. The instructions say to cut the one that goes into the block. But I can't see exactly where it goes. It appears that I am supposed to cut the larger one, and not the one that goes to the water pump.

cut whichever one is the size of the "T"..... either way, you're either including or missing the heater core. ( truthfully, the last time I flushed mine, it apparently UN-clogged debris plugging a leak in my heater core and made a leak, necessitating a new heater core). I don't recall which hose is the feed and which one is the return.

The hose that leads to the water pump is the returning water from the heater core to the engine.and the one that leads down along the passenger side eventually loops back up and goes into the intake at the rear. If you removed your inner doghouse you would see it entering next to the distributor. Anyway The water flows back out of the engine from here and this is probably the one they want you to use according to what you have said your instructions relay.

Same here an 05 with no petcock valve.

I pulled the fan schroud, and lower radiator hose, access everything from the top to drain the radiator.

I also used a radiator flush kit.

Good Luck, Jim

I just flushed the bad brown out of mine and replaced it with good green.

I just disconnected all the hoses at radiator, block/thermostat, heater core,
lines to the rear heater core. Drained out what would fall out via gravity,
then stuck my garden hose into each opening and ran clean water till
it came out clear on the other end.

It was no more work than installing one of those kits, except for
the part about removing and replacing the thermostat. That was
a little cramped.

Ya had me until you said it was no more trouble than installing a flush kit...

Sorry installing a flush kit and attaching a garden hose is much much easier than what you described.

What do you mean by Good Green?

Thanks, Jim

Good Green = Prestone.

I got the idea of the garden hose to coolant hose from one of your posts.

I had to remove a half dozen hose clamps and pull the hoses away from
their nipples. To do the flush kit I guess I'd have to remove two hose
clamps, cut a hose, install the widget, then add two new clamps.

Maybe simpler, maybe not. Certainly not very complex or time consuming.
I liked the idea of flushing it out both directions at every point. That way
I was sure to get the old DexCrud out.

It actually seems like my heater hose is not long enough to add the
flush kit thingie. The length of rubber hose between the heater
box and the metal supply line is only about 2 1/2 inches.

If you flushed in both directions you did very good.

About the Green though...

It's not really green.

As far as I know, Your mileage may vary.

What should the change interval on hoses be? Does anyone know?

Thanks, Jim

PS DexCrud out is a good thing... No matter what you replace it with.

I meant "green" the color. Not Green in the political-ecological sense.

No not eco...

Just green in formulation, its all but gone. You can still get it from John Deere CoolGuard II. But you cannot really by the Green we new as younger men anymore.

It's all gone now. Dex was the first and all the eco weiners caused everyone else to follow suit.

Ah Well... Bring on the PIX. w00t
