Engine battery replacement

Ended up unscrewing the blower fan and after draining the coolant to containers I lifted my coolant tank out of the way and then watching my son and grandson remove the facing board and slowly inched the battery forward until they could get a small 13 mm spanner over the battery lugs- very tight as you said but once loosened they were able to lift battery down onto a blanket I had placed on top of motor -the coolant cap had been removed once all the coolant had sufficiently drained previously from the tank.

It was very simple for me as I watched but definitely a 2 person job with strength in hands and arms- the original battery model type is not sold in Australia by Varta but in my Google searches it is readily available elsewhere. I contacted the company and they recommended their G14 identical in size and slightly more CCA.

Reinstallation was a reverse of above however it was very challenging for my son to tighten the lugs and could have been assisted with smaller length spanner with sides filed down- yep I had one but it was at home - I would suggest that it would be essential to have one for removal and instal in future.
