brownie74 Posted October 13, 2008 Report Share Posted October 13, 2008 Hi, I've been trying to change the coolant on my Toyota Corolla 1992 (seca) but I can't find the plug to drain the radiator. If someone could tell me where it is, it would be a great help. My manual is absolutely useless. I can't see the plug anywhere. I've been under the car, in the bonnet for an hour. No luck. Cheers, brownie Quote Link to comment Share on other sites More sharing options...

Cheers, brownie i don't think it has 1 just undo the bottom pipe and let it drain out from there Quote Link to comment Share on other sites More sharing options...

The manual says it has a plug though. Quote Link to comment Share on other sites More sharing options...

Hiro Protagonist Posted October 13, 2008 Report Share Posted October 13, 2008 i'll give it a go to be honest, i don't remember seeing any pipes that were easily accessible either i will go and check now cheers Jack front of car up Look for a short pipe (like the size and length of your thumb) coming out from the bottom tank of the radiator (pointing towards the engine block) with a tap fitting (like one of those 10L water jug thingies) on the end, and possibly a drain tube underneath it. You may need to move a splashguard to see it. If you fail to find that (or there isn't one), just undo the bottom radiator hose (you can't miss it, it's a big fat f*ckoff black hose coming from the bottom of the radiator. Either works fine, just remember to have a bucket or something underneath to catch the fluid, and make sure the car is cold when you do it otherwise you'll burn yourself.

I found a hose coming from the top of the radiator going to the engine block. I disconnected it. Some fluid came out of the radiator, loads came out of the engine block (about a litre i reckon). Have i done the right hose? Quote Link to comment Share on other sites More sharing options...

If the hose comes out of the top of the radiator, it won't drain the radiator will it? Remember which way gravity works? Look on the BOTTOM of the radiator. And for a full drain you should be expecting somewhere in the vicinity of 5L of liquid (if you drain the block from the block drain tap, which is usually on the block just to the left of the oil filter) Quote Link to comment Share on other sites More sharing options...

What i'm actually trying to achieve is to stop the engine overheating which happens almost every time i drive the car. Seems to be ok when i'm moving but if i get stuck in traffic it soon overheats. Been happening for a year - and topping up the radiator makes it go away - but in the last month seems to have gotten worse. Quote Link to comment Share on other sites More sharing options...

If you have to continually top up the radiator, it means one of two things. 1) You have a coolant leak somewhere. Look for puddles under the car 2) You have blown a head-gasket. Does the car blow white smoke more than usual? Is the oil milky or are there lots of bubbles running through the top of the radiator when the engine is running?

orangeLJ Posted October 14, 2008 Report Share Posted October 14, 2008 should have a drain plug on the bottom (when standing looking at the front of the car) right hand side, right next to the lower radiator hose. Its a little (about 3 centimetres long) black pipe that stems from the radiator, with a small screw in plug in the end of it. Quote Link to comment Share on other sites More sharing options...

Is the oil milky or are there lots of bubbles running through the top of the radiator when the engine is running? I'm afraid it does blow white smoke when the temperature gauge gets towards max. Seems to be happening more often lately. Is it a big expensive job to replace a blown head gasket? Car is till drivable if i keep topping up the coolant.
