specs= mild 350 / q-jet / simply put my motor varies in its temp way to much.. i belive this is because i put in a high flow water pump, that is "outflowing" my new NAPA 3 core radiator. forcing the water through to fast not allowing it to cool. i ran a 195 t-stat all this year because even in summer it wouldn't warm up, unless i was moveing slow and than the twin electric fan i have bearly kept it at 200 /forums/images/graemlins/eek.gif if the above is true /forums/images/graemlins/1zhelp.gif then should i remove the high flow pump and toss in a regular napa rebuild? Or should i toss in a larger (say huge) radiator, so the water takes longer to pass through thus better more consent cooling..which is my objective. Also i have serious plans to put in a 6.5 diesel within a year or so /forums/images/graemlins/thumb.gif. So if the bigger rad would work /forums/images/graemlins/confused.gif then thats one less thing to buy /forums/images/graemlins/grin.gif..
