Car Forum / Peugeot Cars / February 2005406 Heater matrix - much of a job?
This car just KNOWS when I'm about to make a serious trip..... 1998 406 estate, just clocked 100,000miles. I'm driving down to the french alps next week, and yesterday I smelt hot coolant inside the car, and noticed the windows steaming up. Checked the coolant and it had lost about 3 pints since a service 2 weeks ago :-( I dumped a can of Radweld in it, and it SEEMS to be holding up. (although dare I risk the trip with it?)How do you access the heater matrix, does the entire dash have to come out? thanks, John If the 406 is like the 605, the leak is probably from where the 2 pipes enter the heater matrix. A ring of rubber at the union deteriorates with age and the coolant escapes into the right side footwell. Check this before removing the matrix ...

Take care not to use something you just have laying about - some lubricants will destroy the rubber in practically no time at all. I got a set with the two rubber rings at a Peugeot dealers' at the ))reasonable(( proce of GBP 12.

In a 405 they are above and to the right of the glove box, which you have to take out if you are not to remove the whole fascia. Thanks. A useful document! However, the Radweld seems to be holding it for now. As its now clocked 100,000 miles I reckon its about time to get rid and buy a proper car! > Previously in this group someone pointed to an extremely helpful > http://rangerovers.net/repairdetails/heateroring.html > which shows in detail how the matrix connection o-rings work on a Range > Rover, and that part of the connection looks much the same as on a 405. > In a 405 they are above and to the right of the glove box, which you have > to take out if you are not to remove the whole fascia. |
