Hi All,

Stoopid simple question, but thats what i do :p /emoticons/[email protected] 2x" width="20" height="20" />

I am diagnosing a bunch of overheating (in another post).

Doing a radiator Flush - with Kit.

Need to Flush with Heater set to Max heat.

My heater Valve is corroded CLOSED.

SO - should the valve be OPEN or CLOSED for Max heat ?

Thx,

Monza

Hay Monz..,

We wouldn't have anything to do W/O you... >:D< <'>

I suggest removing that valve (they almost always freeze up) & put in a short piece of pipe/tube for now. You don't really need it anyway.

--SO - should the valve be OPEN or CLOSED for Max heat ?--

With the tube in there it's MAX HEAT., as it should be.

BUT., while you have that hose open., pull the other hose off the eng., run a garden hose & flush the heater @ run that ***** water to the ground rather than thru the eng. (Who knows what's in that heater core & hose..???) <_<

Now you can "loop" the hose on the eng. back to the other ****** i.e. by-passing the heater....and/or use some spare pieces of hose to hook up the flushing "T"

Point being., you don't need the heater in the loop for flushing....it's already clean.

NOTE: if a lot-o-junk comes out of heater...then, leave it in the loop so the chemical flush can clean it as well.

Brilliant!

Bloody brilliant.

I have got half a mind to leave the Heater out of the loop - it doesn't work anyway.

Unless the round trip cools the water any ?

Thx Bob.

AAAAAAh.., You're making me blush....... :blush:

The heater is easy to remove & re-build...& cheap. Usually done when heater core springs a leak. Motors can be lubed up & made to work again.

But yah., that lil' bit of circulation & small rad. brings about some cooling. However., NOT enough to solve overheating.

Bypassed the heater for now.

Just looped the send and return on the pump.

Heater not working - so no loss there.

Looks tidier too - MST important.

Probly will order a non corrode heater valve and new hoses when I refurb the heater - in deepest winter - in California = NEVER!
