I have problems with my old 1985 with high engine temps. I removed the http://www.ebay.com/sch/i.html?_nkw=radiator which was cleaned out 12 months ago. I cleaned the bugs from it and the http://rd.bizrate.com/rd?t=http%3A%2F%2Fwww.amazon.com%2Fdp%2FB003R3IHQQ%2Fref%3Dasc_df_B003R3IHQQ4755674%3Fsmid%3DATVPDKIKX0DER%26tag%3Dshopzilla0d-20%26ascsubtag%3Dshopzilla_rev_121-20%3BSZ_REDIRECT_ID%26linkCode%3Ddf0%26creative%3D395093%26creativeASIN%3DB003R3IHQQ&mid=184056&cat_id=22000200&atom=10681&prod_id=&oid=6141772012&pos=1&b_id=18&bid_type=4&bamt=45e4b920dcffc474&cobrand=1&ppr=e1db1ac25347c572&rf=af1&af_assettype_id=12&af_creative_id=2973&af_id=615103&af_placement_id=1&dv=3a053014e164133b67cff78b9cd51dd4 with compressed air, followed by high pressure cleaner (being very careful with the fins). Checked fan belt tension. Replaced radiator and flushed 5 times with water before adding coolant system cleaner. ran http://www.ebay.com/sch/i.html?_nkw=engine and temp came to normal (71C thermostat fitted). Then went for a drive and when the auto transmission temp gauge started to climb, the engine temp did likewise. using an infrared thermometer I got 92C at top inlet of radiator, 71C at outlet at bottom of radiator, and ambient air temp was 36C that day. The radiator is working due to 20C change in water temp. Fans are pulling plenty of hot air through. I feel that the under-hood temp is flowing under the vehicle and heating the auto trans which then heats up and passes its heat back to the engine by the stock cooler mounted in front of the http://www.ebay.com/sch/i.html?_nkw=radiator. The whole car is standard. I am going to again check the temps of the inlet & outlet pipes of the trans cooler. Does anyone have any ideas on how to reduce these temps? Thanks, bushtrev.
