another question here (actually more).
Yesterday while exploring under the hood I noticed the following, there are
4 steel "cooler" lines in the radiator of this truck 2 on one tank and 2 on the other. Additionally on the lower passenger side just behind the grill there is another cooler. Questions are what is the outboard cooler engine or trans? And, can someone tell me what the routing of the lines are. Again this truck is a 98 K1500 Suburban with a 5.7 engine. Thanks Larry
