Can someone please tell me where exactly the coolant drain plugs are. I have a 95ts 4cyl. Are they really a must do? cause i heard they are a nightmare to get off. Will i need sealant when i re-install the plugs.

Cheers..

Only one on the 4 cylinder block, but I think it is well hidden under the exhaust system. Why not just flush the whole system with tap water a few times, and use concentrated coolant?

Yeah mate found it, got to take off the heat shield first and there's another shield that protects a sensor. Its not far from the water pump. I tried to get it off, its on tight allright. Soaked the nut in wd40 and will try agin later. Snapping the nut is the last thing i want to do. Your idea sounds like the safest option. Any idea of how much water will be left in the block after flushing.
Thanks for the advice.

I never take them out as its possible to snap it off or damage the thread in the block. I drain the radiator with the radiator cap off when cold by opening the tap in the bottom tank, then letting it drain into an old container, it looks like you get about 4 or 5 litres out. Refill with tap water and run the car, with the cap off. As soon as there is warmth in the radiator top tank (feel with finger) and you can see the clear mix with the old coolant. Engine off, drain again. Allow to cool. Repeat several times, until the water coming out is clean tap water, about 3 times. With the radiator drained I put in the correct volume of concentrated coolant (get one that is ok with tap water, the one I use is good for 2 years with tap water, 3 years if the system is completely drained and filled with distilled water). Fill up with water, run the engine with cap off and top up as necessary. Remove and clean out the overflow bottle and put some diluted coolant in that, fill it up to the full mark and keep an eye on it as the level can drop quite a bit in the next week or so. When you warm up the car first time after changing the coolant, keep an eye on the temp gauge and see if it acts normally.
