So my buick 215 is getting to hot. I wasn't sure how accurate my gage was. On my way home from Parts obsolete swap meet on sunday it was in the mid 90's. My engine temp got up to 230 but seemed to be doing okay. Then it started cutting out on me. I pulled over to let it cool a it. After a good half hour I drove the rest of the way home. Engine temps were still close to 230 though. I have an old school setup I think.
My question is what radiator setup are you using? Also what engine temps are usual for you? Just trying to see which way to go. I'd like to make it better without forking out another grand for renegades new setup right now. Suggestions please! |

QUOTE You need to check for air in the system, timing being way off, and for a lack of airflow. Steve and the Dr. are right. Please check all the cooling components and their functionality before jumping the gun and buying a new radiator. I have noticed on my set up that the fans are working more often than not... I'll notice they are are on and running at freeway speeds on occasion. I have done many hours of testing and learning through trial and error. One thing I have noticed is if I let the car sit and idle w/out the fans hooked up...my engine will overheat and blow the cap off my overflow tank spewing coolant everywhere. This will happen within 8-10 minutes of idling. With the fans hooked up, the car can idle until the gas runs out of the tank at 185-190 degrees on a 90 + degree day. Those fans need to work and be designed to move a lot of CFM. Also, air in the lines can be troublesome in a car with 20' of coolant lines. Renegade told me they drill a small 1/8" hole in the thermostat housing to allow coolant to bypass the closed thermostat when filling. Also, a breather on the radiator is a very good idea. I even back fill through the breather when I'm filling a dry system. I would bleed the system first, check the coolant mixture, then check the condition of the water pump and lines, then think about replacing the radiator...in that order. If you find the radiator to be your problem, buy a good one and be done. Hope this helps, Bill |
