happy new year to all out there, if someone out there has a 1999 4wd pajero petrol 3.5 auto nl could you please tell me where the heater hoses connect to heater under bonnet as i want to flush heater . looked up pajero club and checked haynes manual but no actual info as to where thy connect firewall any info would greatly be appreciated thank you james
Hi
Finding where the heater hoses hook to the firewall is easy, worries me that if you cant find them what is your ability to then flush and bleed the cooling system. My advice would be to go to a cooling system repair shop and get a total flush done to your cooling system
cheers

Heater is located on the left side of the vehicle. There should be 2 hoses about 17 mm outside diameter running from behind the engine to the firewall. Access to these hoses is not brilliant. When the engine is running, coolant passes through the heater core all the time, regardless of the position of the heater controls, so why bother to flush the heater anyway? You can never fully drain the cooling system, so the best method is to flush as best you can (remove the lower heater hose and refill with water), then flush again, and if you have doubts, flush a third time. Any residual coolant in the system will be diluted well and truly by the new coolant being added.
thanks to blaze and erad for your input heater not working , no leaks so was told to flush heater out and see if that fixes it once again thank you james
