Coolant Issues

[g60Dazzaman 0]

There is too much pressure in my coolant system, Stevemac told me that their is probably a block in the system somewhere, does anyone know any sort of product i can stick in the system to free it up?

Try flushing out the system as if their's a blockage this is the best thing to do and pop some lovely fresh coolant in :D

Yes but what to flush it out with? Is it a case where i need to take the water system to bits or is their a product available that will free up a blockage?

Flush it out with water from a hose, you can get a chemical to use first but not sure what it's called. The blockage in cooling systems generally appear in the radiator so just back flush it to see what appears.

Flush through with loads of clean water. If that fails to unblock then its time to start removing hoses etc.

I have used Wynn's cooling system flush on all-iron engines with good results. However, I haven't tried it on lumps with alloy heads... anyone know if it's a really bad idea?

I think you could dislodge some muck only for it to get stuck somewhere more critical, I don't like oil or coolant flush chemicals for this reason on old engines, fine if you regularly use it on a newish one.

Fair point, although in the engine I used it on it doesn't just break big chunks free - it breaks the bits down to a size where they probably wouldn't get stuck anywhere. This seems like a better idea than just trying to move stuff around with water?

 

I'm just a bit paranoid about the chemicals attacking the head.
