Does anybody have a picture of the engine from a mk1 .Looking for the heater matix pipe that comes out out the bulkhead and runs down to a metal pipe.My one seam to have a kink in the bend at he bulkhead.Did a service on her at the weekend plugs and think i might have put an air bubble in the system ,just had a major overheating problem today and think its all down to this pipe and the kink ?

Have a look [url="http://www.toyodiy.com/parts/p_E_1997_LEXUS_GS300_JZS147R-BEPQFW_1603.html"]here[/url]. If that's not quite the right bit, then you should be able to navigate to other pages to show you what you need.

no heater pipes that i can see

Umm ok, maybe not on that diagram because I'm not 100% sure what I'm looking for. But you could navigate to a parts diagram for any part of the car you like.

How about [url="http://www.toyodiy.com/parts/p_E_1997_LEXUS_GS300_JZS147R-BEPQFW_8716.html"]here[/url] ?

Spot on mate thats the one the 87246A if anybody has a picture of this one it would really help at lot

ok, you need to look at the listing on the right for the actual part number (e.g. if you were to order one from a dealer), which is 87245-3A500.

It doesn't look like it should be that expensive, approx £30 and if you join LOC as a Gold member most dealers will give you a discount off that.

Or try a breaker's.

Or if it's just a silicon hose then maybe you can just buy a suitable bit of hose and get it made to the right shape ? Sorry I have no idea about doing that, but surely it is possible ?

MK1 in a breakers in St Helens/Newton area.

Do you know the name of the breakers or where about it is

You mean the pipe that you can see in this pic?

I'd be surprised if it would cause an overheat if I'm honest. It shouldn't be performing any major function on the cooling system at all, just part of the cabin heating. You could cap both sides off and it shouldn't cause any issues for the engine side of things. infact, if you turn your heater down to cold, it would have no flow anyway.

the one under the word rear,but if that has a kink in it will that not the water flow around the system

It shouldn't cause any problems. If you look at the other water pipe coming through the bulk head and follow it round, pretty much straight in line with the back end of the engine you will see a black block screwed to a bracket on the bulkhead, with a lever and a cable clipped to it. That is the flow control for the heater. If that is completely closed (when you set the heater to 16... the coldest settting... on your heater controls), there will be no flow through the pipes, including the one you are talking about. Basically, the cabin heater water supply is not part of the engine coolant flow path, just an offshoot from it. So if you cut the heater pipes and capped them off, it would make no difference to the cooling of the engine under normal conditions.
