Hi all ..

Im replaced the head with a EL 95DT tickford head on my NL instead of the AU3 head that was on it ...

Now, is it true you are only meant to run water for the first few 1000kms and then put the coolant in? or can you put coolant in straight away ...

Please let me know!!!!!

Thanks heaps guys! you all rock!!

Luv, Laticia.

I've never heard that in my life. The only reason i'd ever adhere to that is to make sure you have no leaks equaling a waste of coolant once you fix said leak.

When doing work to the cooling system, i usually run for a day orso with water for the above reason, once i'm happy there is no leaks, in goes the coolant.

I'd make sure when you drive it with test water, do it more than just around the block, give the engine enough time to completly heat up. You want it to get to its proper operating temperature, because if there is a problem, it may only be when its fully warm that the gap will open and leak, so you may miss it.

Have a good look along the block/head under the manifolds, and look at all hoses. As long as the block and head surfaces were flat, and work was done good, it should be fine, but a test is always a safe option on such work.

i always got told to run straight water for a week or so. retension the head bolts and flush and fill with coolent. gives the head gasket time to settle or something like that

In fact DON'T RETENSION THE HEAD BOLTS!!!!! They are designed to be tensioned once.

the 'water only' rule is if you use gasket adhesive and dont want chemicals from the coolant stopping it cure properly

if you use an AU metal gasket you dont need any adhesive, therefore can stick coolant straight in

There are chemicals in the head gasket that react to the Ethylene glycol found in a lot of coolants.

From the ACL 05 gasket book
Quote:

Monotorque gaskets are silicone coated and NO additional sealants should be used.

When installation is complete the engine should be filled with water, brought up to normal operating temperature, allowed to cool and then drained. Coolant in accordance with the manufacturer’s specifications is to be mixed with water and then the engine refilled.

Another problem with Ethylene Glycol is that it can track along the fibres in a gasket material which can cause leakage problems with gaskets.

Thus the reasoning behind allowing an engine to reach operating temp before you add coolant. The heat will set the chemicals in the head gasket off and help with sealing. i have seen a brand new head gasket start to leak as the coolant tracked to the outside.

The head gaskets are coated in a viton rubber and NO sealant is to be used as it acts as a catalist to the coating
