Can anyone give me heads up on a 100 Series leaking heater, I've been told that there is no heater tap. It just uses a flap to direct hot air around. I believe that you have to remove the whole dash assembly to get to the faulty part. I'm in the eastern suburbs of Melbourne and would like to take it to someone who has complete this before.

sounds about right theres a few hours required to remove the dash assy, the main heater box assy is on the passenger side of the vehicle

Did one last week, dash out about 7 hrs if done before.... or 3 days if you haven't.

Try Karair, done Denso training courses with the guys from their and they are pretty switched on.

Hi Paul k11. I had mine done a month ago in Horsham Vic. They completed the job inside 2 days, The local toyota dealership Quoted me 3 days. Everything had to come out one piece a a time. The mechanic showed me all of the photos he took as he was taking it out, so he knew how to re wire everything and so it went back as it came out. He said it was a long time since he had done one, Oh and he was right, the bill wasn't pretty ! Lol.... When I turned up with the problem, he disconnected the 2 heater hoses leading into the firewall, then connected them using a joiner, that stopped the coolant flowing through the heater core. Which stopped the leak until he could do the job... The air con also has to be disconnected, so will need to be re gassed. All the best.

It would have to be tempting to try some Bars stop leak first?

As a matter of interest how old is the vehicle and what type of coolant was used?

Yeap spend $8.00 on Barsleak, clog up the radiator and the heater core still leaks..... destroy a head due to over heating....... total cost now $3500....

Any form of stop leak in anything is flirting with danger.

Fix it right the first time and it might save money in the long run.

Bars is actually used in new engines in the US by the manufacturers straight out of the factory. Liquid Aluminium is the current product.

I have not used the new product however can say with certainty the old formula works and have used it without issue in a number of tractors used for broadacre farming and loader work to stop minor weeps over a long period of time and have not experienced any problems.

Maybe not all products are equal?
