moparvwfreak Posted July 5, 2009 Report Share Posted July 5, 2009 alright, my 73's temp is acting weird. runs nice and cool when in town but at speed on the freeway, it heats up almost to the point of overheating. i know the rad isn't the best but its what i have. if it were the rad, wouldn't one think it would overheat in stop and go rather than on the freeway??? also could the water pump, although new when i got the truck last year, not be circulating enough at freeway speeds, but enough to keep it cool at lower, in town, speeds?? i would really hate to have BOTH my 620s down for drive train work.

Z-train Posted July 5, 2009 Report Share Posted July 5, 2009 Sounds like the radiator is plugged. Quote Link to comment
DISLEXICDIME Posted July 5, 2009 Report Share Posted July 5, 2009 Sounds like the radiator is plugged. i agree it sounds partially plugged. I had a datsun that did that the upper part of the rad would get hot but the lower driver side corner would stay cool Quote Link to comment

moparvwfreak Posted July 6, 2009 Author Report Share Posted July 6, 2009 well i drained out the coolant, adn added in my super rad cleaner. drove ti all over from home to bothell. normally it would heat up just getting 7 miles out of town. but today she never got above the 14 way mark. i think that helped it. i ahve ot go all over hells half acre tomorrow getting parts for my passat so after that i shoudl drain it nad clear the system. and of course refill it.
