Yeah very common.

If you had searched the forum you'd have seen multiple threads on this subject.

Had this on my f and just needed regas.

do you mean regas the ac? if so how does that effect heat coming off the heater matrix?

[ChrisIS200SportTTE]

It's absolutely nothing to do with the A/C on an IS200 or IS300.

It's very very common. It's the heater matrix or trapped air in the cooling system. Sometimes flushing the heater matrix works, sometimes burping the cooling system of air works, sometimes you need to do both, sometimes you need a new heater matrix

yes i know that i tried everything over a 6 month period .eventually i replaced the matrix this solved the problem

it really is quite easy to do, takes about 2 hours

[Stuno1]

Fair enough :)

[Dazzer306]

If it is heater matrix hope it's not hidden. Right behind dashli,e in 306 I did, complete dash had to come out don't want to do that again will try to burp out air bubble if it this and see from there

Don't need to take dash out some one on here done it by removing the pedals

[shortfuse]

just remove the clutch pedal and you have all the room you need

[Dazzer306]

Had rad cap off and the water is a rusty colour, so think it may need flushing out

[clifton 94]

Flushing never works replacement is the only cure really

[shortfuse]

i agree with the previous posting only replacement is the answer

[shortfuse]

when i took my matrix to the rad specialist it took 2 hours of high pressure flushing with chemicals to clear it of all the crud
