| ther is a block coolant drain plug. i think on that year it is on the pass side of the engine and behine the engine mount near the back of the block. some of the newer ones are infront of the engine mount on the pass side. i think if it is a regular bolt head on there it is a 16mm but some have an allen head on the drain plug. i think if it is an allen head the size is like a 6mm, although i might be wrong on the size of the allen head bolt it has been a while since i have done one of those. but the drain plug is on the pass side of the engine no matter what. |
