hi I've got a problem i need help with? i have a 94 c2one 2.0i 8v. the car seems to be getting to hot on short trips thhe temp gauge goes to ninety in space of ten miles and fan kicks in, i stopped and checked the other day and the pipe from thermostat housing to radiator was swollen abnormally. so last night i took out radiator washed it out and washed out whole system. the only thing i noticed was the top exit  of water bottle was a bit bocked with limescale or summat so i cleaned it out( think it goes to inlet manifold). then tonight the fan kicked in got home had a look and pipe bloated again. as soon as i take off water tank lid it goes back to normal. can someone please make a suggestion please !!!!!!!!!!

The  fibres inside the hose thet help it to keep its shaped have stretched or broken- very common, no amount of system flushing will fix it so dont waste your time. You need a new top hose you do.
