Hello all I am experiancing a strange problem bith me ES. The temp guage slowly creaps up to near or into the red zone(the oil temp guage reads about 7 o,clock). The engine does not seem to be too hot( no power loss). The stragness comes fron the rad. After one of these hot spells, after the engine had cooled I opened the rad cap(not the overflow cap) and to my surprise the rad was low on coolent even though the recovery tank was at the specified level. To curb further problems i instaled a new thermostat, rad cap, and recovery tank cap(all new from volvo). I refilled with 50/50mix coolent and drove away. Again the heat went up and agin the rad was 1/2 empty. I refilled again and the symptoms remained the same. Is there a bleeding technique to this system? I have no apparent leaks(clean garage floor), but the overflow tank does just that when hot, but stays full when all cools down. Any suggestions or paST EXPEIANCES?

Merci

Yvan
