![]() The problem with that old chestnut is that k seal / steel seal etc will block up the heater matrix.

Best to fix the problem right 1st time instead of a quick botch in a tin.

What is most likely to be the cause of this, provided the system has been bled correctly, is a breach of the fire rings on the head gasket allowing combustion gasses to enter the water jacket space. This is the type of failure that is claimed to be "repaired" when adding magic potion fixes such as K Seal and Steel Seal. In reality what happens when these are added to the coolant, the small passageways in the cooling system, and especially the heater matrix become blocked with the "magic" and their efficiency is drastically reduced. The top and bottom of the matter is simple, the underlying cause needs to be investigated properly or the result will be a completely ruined engine. Brian ![]() |

I suspect you mean there is hot water going in and out - which is of course required, but it doesn't mean the matrix isn't substantially silted up. You can't determine anything by feeling the hoses. Unless hot water is flowing through at the correct rate, you will not get any effective heating. Again, assuming that the coolant temperature is where it should be (see the Diagnostic Mode info) then as advised earlier, look at flushing out the matix and take things from there. TC |
