If we are to handle the system pressure by running low pressure caps and not replacing "routine" parts then alot of people do replace engine much sooner than 15 years.
The car in the picture is bone stock with each every thing to factory spec. If something is broken or worn off it is replaced. It has 115K on ODO and still runs fully synthetic 10w30. It is a prosmatec.
I clocked over 200k on my 2001 City on stock engine and is currently in use of a close friend. Every thing is at factory spec..
I also have 2004 Vario with 135K on stock motor. It was a mess when i bought it, at the moment its a 100% trouble free car because all hanky panky ustidian have been removed....
At OP, Brother there is no shotcut to fixing on overheating Honda. You can search the threads throughly, if you wan't fix the car and wan't it to reliable you WILL have to fix EVERYTHING related to cooling system. If you have been running plain water in your radiator, you need to get the water pump checked. It starts loosing its shrouds, it should be checked and if required replaced.
Next is to check your Radiator Cap and thermostat, replace if they are out of stock configuration. You need an OEM 1.3 Bar Cap...If you're running anything lower you might end up blowing old rusty pipes or Radiator. If that happens go ahead and replace. Get everything in order and than check if problem presists. If it does, you should check the HG. Although with the positive pressure on cold engine and hard hoses in the morning, i am almost certain that you are loosing combustion into the system. Now that could have happened because of weak water pump...
Weak Water Pump >>>> Over heating>>> HG blown.
Thats the reason i wouldnt suggest replacing HG as the first line of action. If you replace HG now you car will probably run fine for a while until it gets blown again due to out of spec system.
- Water Pump ... 1600/-
- OEM CAP form HONDA 1300-1500/-
- HOSES - Depends on quality
- Radiator 5 - 6K (plastic housing)
- HG metal one (3-5K)
- Labor should be 5K
You need a professional job for HG, Most mechanics will try to force you to use cardboard Gasket,,, why because its easier to replace and seals better initially but gives up underload.
