100 series heater leaking

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?
