Welsch Plug locations

Hi guys.

Been having temp issues for the last week or so. Qill run normally for about 20 - 30 mins then spike and drop rapidly. By the time I get to work (50 - 60mins) I need to fill the radiator and cooling system.

There seems to be a drip coming from the left hand bank, behind or above the A/C Compressor.

I know I have seen something about this here before but can't seem to find it tonight for some reason.

Any help would be greatly appreciated.

Thanks
Jay
