04 scion xa waxy radiator no heat

Showing 3 out of 6 Posts | Show 3 Hidden Posts
Question From peaceablegarden on 04 scion xa waxy radiator no heat

We're stumped. My very well kept 2004 Scion xa with 70,000mi started having heating problems late last spring. It stopped working, then worked some, then just conked out completely (only blows cool air). Didn't worry too much about it until now. My friend who is also my mechanic and I looked it over yesterday. He did much of the basic troubleshooting for the quick to look at stuff like switches. When he popped the radiator cap off to check coolant, we found what looks like a waxy sustance around the just inside the radiator at the top. We're just stumped. We have no idea if the waxy substance is related to the heat not working (maybe there's a blockage somewhere) or if it is another problem or it's not a problem at all. Frankly he and his other car buddy have never seen this waxy stuff before. I've done some basic google searches only to find potential issues ranging from no worries at all to a blown head gasket to tranny fluid mixing with the antifreeze. There does not seem to be any other problems. I have had no over heating (my heat has been gone since late last spring) and no other issues. He also did an oil change so we had a look at the oil and we removed about a quart of antifreeze and saw nothing unusual. I would welcome any other thoughts. Thank you.

Response From Discretesignals

Can you take a picture of the waxy stuff and post it in here?

With the engine warmed up feel the heater hoses. Are they both hot?

Response From peaceablegarden

Sorry, we cleaned the waxy stuff off. Waiting to see if it builds back up. If it does will take a photo. Yes, they feel hot but perhaps not as hot as they should be.

Response From Discretesignals Top Rated Answer

How about the upper and lower radiator hoses? Are they both hot after the vehicle is driven or has been idling for a period of time? With the ac turned off, does the electrical cooling fan kick on and go off after the vehicle has been driven and the engine is idling.

The thermostat uses a wax pellet (hint) to open and close the thermostat's valve. Maybe removing the thermostat and flushing the system out including the heater core is in order. While you have the thermostat out you can test its operation.

If the thermostat is hanging open the coolant temperature will be too low while driving and will affect the operation of the heater core's output.

Yes, both radiator hoses are hot. Haven't noticed about the fan. Yes, I believe our next plan is to remove the heater core and flush out the system. The thermostat was replaced less than a year ago, but I suppose that doesn't mean it can't fail and we thought about that. I think part of our plan to look at it for sure.

Let us know how it turn out.

white paste in coolant system

Question From peaceablegarden on white paste in coolant system

My car guy and I are completely stumped.

Details: 2004, Scion xa, 70K, standard, well-kept

History: Heat stopped working, upon inspection of radiator cap found a white thick pasty substance. Found leaks in radiator. Car did not overheat at anytime.

Work done: Replace radiator, flushed system (chucks/pieces of white substance came out), added new coolant, heat still did not work. Drained and flushed system again, replaced with straight water, ran car and it heated well, drained. Filled again with radiator flush and water, ran and heated well. Left water and flush in system 2 days. Less than one hour of driving resulted in complete radiator failure (we actually believe we had a defective radiator). Flushed (more white chunks/pieces came out) and added new coolant, heat is not working again.

It appears that whatever this substance is that is solidifies in coolant but dissolves in water (heat works fine running coolant system on straight water). It does not seem to be building up under the radiator cap any longer, but does appear to be building up in the heater core or at least that's my theory.

We do not believe this is a blown head gasket. I'd welcome any thoughts. Thanks.

Response From Discretesignals

I don't think that you are supposed to leave the flush in the system for that long. Might be why the radiator failed. You also have to understand that the water pump seal is lubricated by the additives in the antifreeze. Running straight water and flush probably doesn't go to well with the water pump. Time will tell.

White substance can be one of two things. Oil from either the crankcase or the thermostat wax pellet came apart. Since the top of the engine is fed oil through a passageway between the engine block and cylinder head, a head gasket problem in that area could cause engine oil to get into the coolant ports.

The thermostat has a wax pellet that is used to open and close the thermostat's valve when the engine's coolant reaches a predetermined temperature. Probably wouldn't be a bad idea to pull the thermostat and inspect it.

Response From peaceablegarden

Thermostat has been replaced. Sorry, forgot to mention.

Response From Discretesignals

Can you take a picture of the substance and upload it to a picture hosting site and send us the link?

Response From peaceablegarden

Sorry, alas no. It has been cleaned out. What I can tell you is that it is sort of pasty and was not mixed in with the coolant but rather collected around the rim of the radiator cap and was coming out in bits when flushed. It was quite white.

Response From Discretesignals

From your description is sounds like oil in the coolant. Since you had it cleared out, you'll have to see if there is a reappearance later. If there is, you'll have to do some investigating.

Are the coolant hoses to the heater core hot when the engine is at operating temperature? Have you tried back flushing the core? Make sure you use Toyota Super Long Life coolant (pink).

Response From peaceablegarden

I believe we may have found our answer. Apparently coolant, if old, can create a residue - silicate (though we did a flush and replace about a year ago). I think this is what the white chalky, pasty substance was we found that seems to be gumming up the heating core. It might also account for why there is heat when it runs on straight water and not with coolant. My concern is this. If we replace the heating core, frankly after flushing three times with little or no help doesn't seem to be working, my fear is that there is still this old residue still floating around that would clog up the new heating core. I'd welcome thoughts.

Response From Discretesignals

That weird. Your coolant system should be using Toyota Super Long Life Coolant which doesn't have any silicates in it.


COOLANT TYPE: In order to avoid technical problems, only use "Toyota Super Long Life Coolant" or similar high quality ethylene glycol based non-silicate, non-amine, non-nitrite, and non-borate coolant with long-life hybrid organic acid technology. Do not use plain water alone.


Response From peaceablegarden

Yep, we get that now, of course too late. I am still wondering about how to make sure all the silicate is out of the system before replacing the heater core or how to get all the silicate out of the heater core so we don't need to replace it.

Response From Discretesignals

You sure it is silicate, because toyota super long life isn't susposed to have any silicates in it. Not really sure how you would go about getting that out without multiple flushings. Did you remove the heater core hoses and try backflashing the core out? Your hoses should be hot for the core to work. Maybe you have air pockets trapped in the coolant system.

Response From peaceablegarden Top Rated Answer

No hoses are not hot, though today after an hour's drive, there is some improvement in heat. It's certainly not fully back but probably about 40% better than nothing but still a way to go. Once heated up you can turn on the head and it will be hot for a couple of minutes until it cools off again.
