I run a Std rad,

About temperature...my extra gauge has just broken (but as I remember it showed about 95-97 when fans cut in, and went down to about 90-92 when fan stopped...I think )....but the org gauge shows between N and O (In the NORM sign)...closest to N when running. It does not hit the red spot before the fans kik in...but the difference is that the fans keep on running....for example, last night after a meeting we went into a gasstation and just before in a roundabout the fans started, and they stayed on for as long as it took my friend go in and out of the station...about 4 min ...then we took of after about 500 meters they went of. then I went home and they started again on last bit of road (going slow due to some stupid speed bumps) ..and when home I let it run for a long time (didnt time it)...but in the end I switched the engine of and fan was still on... :-(

the thing is that until a couple of weeks ago the fan would run for about 1.5-2 minutes...witch felt ...ok.

also before the engine change temps where much lower..and fan didnt run quite as offen (the "new" engine is a 4x4 instead of the old 2wd one)

Oiltemp shows 85-92 deg when going.

Last ..maybe a stupid question ...but ... how do I check for an airlock...(I take it was done when it was put in...but)...?
