1994 Toyota Celiac, coolant and water from exhaust after coolant flush. Sign In

Pretty new to car maintenance, but I learnt a bit off my dad so I decided to flush my radiator as it was overdue.

Anyway, I drained out the old coolant and added pure water (I didn't have enough distilled water so I used half and half tap/distilled). But, when gave it some gentle revs, the car started smoking (white and thick). Thought this was a little strange so I stopped the car, drained the water and filled it up with 50/50 of the new coolant.

After starting the car again, it was still doing it, but only once its reached temperature. It is too bad to ignore, and smells really sweet like coolant. Water will drip out of the exhaust which was not happening before (not your usual condensation). The more I rev, the more comes out.

I did the basic head gasket checks on other forums but showed no obvious symptoms. No bubbles from the radiator and no water in the oil. Any advice would be much appreciated!

Thanks in advance,

Miles.

Coolant has to be making its way into a combustion chamber(s) for it to smoke white and smell sweet out the exhaust. Remove all the spark plugs and then let it sit overnight. Use a flash light and look down into the cylinders to see if any have coolant in them. If so, you could have a cracked head, head gasket leaking, etc. allowing coolant in the combustion chamber(s).

Thanks for the swift reply, I'll have a look at that.

Come to think of it, when I last serviced it, a couple of months back, the guys at the garage fixed an oil leak by changing the rocker cover gasket. Do you reckon this has anything to do with it?

It's not about a valve cover gasket from a few months ago. Just what the heck did you do in flushing coolant and how did you fill it?


Something was wrong before you started most likely or it was done all wrong somehow?


Water/coolant out exhaust is not a good sign and can't think of why quite so easy if just a normal flush of coolant? What happened?

Pretty sure something must have been wrong before I flushed it. Pretty sure it was leaking coolant before as the level was slowly dropping. The radiator cap seal went just before the service, and it near overheated on the way there so I stopped the car and got it towed.

As for the actual flush, I followed instructions for my vehicle. Found the drain plug for the radiator. I didn't flush out the engine though. Left it to drain. Filled it back up with water, turned on the heater and rev the engine a little, nothing over 2/3k and that's when the trouble started.

OK - It was leaking before and you didn't really flush anything just drained and filled radiator with just water. You seem caught up in "distilled water and "tap" water" an issue alone would matter if you knew tap water was somehow really bad. You add a mix of antifreeze and water not just water BTW so IDK what instructions you were following. You really can't fill the cooling system drained from the radiator quite so easily on anything so it must have overheated again when attempting to fill it?


Radiator cap probably didn't blow out the head gasket probably did but need to test that all out.


Seeing water out the tail pipe isn't good news for a head gasket being the fault and subsequent problems from overheating. If you noticed at all it must have been plenty hot and old enough didn't need any extra stress on things.


What do you want to do? Can you test this out like a pressure test of cooling system? If so, take spark plugs out as I expect you'll fill a cylinder with coolant and cranking it full of liquid might just end this whole game.


Your call always. If the car is worth it overall probably send it out to be diagnosed and probably find out head gasket it the fault and told it wont be known if more is needed until apart and head sent out.


Get some clue as to costs so you can decide on to fix or make a decision on keeping this car IMO might not be worth it if found to be a lot of work to fix all this - gasket job, new coolant and flush for real, oil change, any hoses, belts this would be the time to either do it up or bail out IMO,
