Overheating, Steam At Bulkhead Exhaust And In Cabin

Just set off to go out for a haircut, when I noticed some white smoke coming from the exhaust. This had never happened before so alarm bells started ringing right away. Then I noticed the air in the cabin was freezing cold.

Then just to make matters worse the steam/smoke starts coming into the cabin

I had turned around and drove home right away, once I got into the drive I noticed steam coming out at the rear of the engine.

It's likely to be worth mentioning that when I was out in the car during the week, the air would only get hot when I was driving at speed, whereas if I stopped or drove rather slowly the air would get cold and the temp gauge would rise to over 200oF

Opinions please folks.

Heater Matrix at a guess

That's not good. Just been out and the steam has cleared, I'm left with coolant all over the back end of the engine, pipes and bulkhead.

Is there anyway to determine if it's definitely the matrix?

If you have coolant over the back of the engine bay, that leans heavily to a pipe with a hole in it. There are two pipes that connect up the matrix. Have a look at them. It might not be the matrix but rather one of the feedpipes. If it is inside the cockpit as well, I'd hazard a guess that the split in the pipe might go into the bulkhead as well.

Right took your advice, had a look at the hoses. The first one is sound. looks as ggod as new, then the 2nd one......I looked at it at first and it looked like a thick strand of hair, then on further finger probing I found my finger half way down the pipe

Any ideas on the part number? Just uploading pics

Thanks again Gav

hehehe, you are welcome chap. (Steady on with the tongue *grin*)

I'm sure someone will be along with the EPC shortly.

The bad news is that the pipe runs all the way to the heater matrix (I believe), so you have to pull the matrix out really anyway (I'd personally change the matrix core at the same time, so you don't have to worry about it for the next 10 years)

The pipe is just a section joined by two jubilee clips one looks a PITA to access and the other seams easy enough for an novice. It's just a bend, so fingers (and toes) crossed the dash can stay in place.

I had the exact same problem and changed the pipes, no need to remove the matrix, would be a good idea to check any other hoses as well as they'll probly be in a similar condition, infact i'd just replace them job done.

Dont have any part numbers but Steve Manley, Toyota Oxford has never asked me for part numbers so possibly worth a call and gives good discount.

dont forget to get some cool red coolant while your at it

Yeah, seeing the pictures and having a quick look in the shed... it is the metal pipes that go to the matrix and the soft pipes run up to the bulkhead

Yep its a bit of a squeeze but not too difficult as long as the engine is cold

Cheers Dunk, I'm gonna give him a call shortly. Although he struggles somewhat with my accent

All the other pipes seem to be in quite good condition, just appears to be this one that as popped.

Good spot mate Its hard to identify the pipe on the parts catalogue...

Would you like me to call him on your behalf

Another quick question, and probably a thick one. Would the split in the pipe cause the heating to behave erratically like the other night?

I'm gonna go down to Argos and buy one of those Fisherprice computers that talk and say words, put that to the phone, job done.

Yes i'd have thought so, i caught mine straight away though as i was showing a mate under the bonnet after getting to his house and the hose let go.

And it isn't pitch dark , when mine went pop I was on the way back one night on a country road and I had to bodge it by jamming two screwdriver handles into the feedpipes so I could get home all by the light of my mobile phone (Oh yes, that was after having to look for the rad cap which I twisted and shot off somewhere in the dark)

Think you should tape the conversation as ive got to hear this

Love the part about the rad cap

I was rebuilding a mates bike engine by torch light years ago and lost one of the little end circlips in exactly the same way, only took an hour to find it lol

I'm tempted to give this a go myself, as It would probably be just as difficult getting it onto a trailer and to a garage What is the long pipe that runs past the two matrix pipes though? As it looks like that will need to be pulled off?

It's either that or I do a Steven Hawking with a Glasgow twist.......not good.

Tried calling but no answer, guess I'll just need to be driven tonight in the chariot of death by the missus:(

Just drink lots and you'll be fine

Just drink lots and you'll be fine

I haven't touched a drink all year

To be honest I'm rather chuffed by the outcome of this, albeit I'm off the road for a week, but I had anticipated it being the water pump and a few hundred quid out the window.

Just spoke to Steve and told him you would be calling, he'll be there till 1 pm.

Told him you were after the 2 heater hoses that go to the matrix

Also warned him that your Scottish
