Similar situation here...had the water pump replaced as well as a bunch of other things done during that service and opened the bonnet the other night to find the radiator reservoir tank lingering on low.
Interested in doing a reverse flush and bleed of the cooling system
as described by Toyboata. Just wanted some clarification on a few steps?
- Where is the heater tap? I think I can see it; the top of the radiator has a thick hose leading to the tap, then two smaller hoses jutting off the tap? Does it matter which of the two jutting off is removed?
- In Step 9: where it says water, do you use coolant?
It looks simple enough a process...just a bit cautious as water seems a real concern to any diesel engine. Or, is it recommended to top off and wait for the 96mth/160k service where the engine coolant is replaced anyway? Would request a reverse flush and bleed during this service.
If anyone can provide pictures of the tap and relevant hoses, that would be really helpful as I'm guessing at the moment.
EDIT: Here is where I'm assuming the heater tap and heater hoses are. Fat hose with clamp beneath the rocker cover clamps to the heater tap; then you have the two hoses, one that seemingly wraps around the back of the engine area and one that runs towards the battery. These are all dead center in the image. Can anyone confirm?
