Overheating!! - Troubleshooting not going well, need input
swapped a '90 350 stock tbi into a 91 S10 Blazer. swap went without incident, but having issue with operating temp. so far we have upgraded to 82-89 corvette radiator, & derale 15" Hi-Perf fan. the temps hover at 210 and will go to 230 in traffic (w/o AC). i even installed 2 electric pusher fans without improvement. been thinking maybe the water pump not flowing enough and or fan not big enough. don't know if the water pump is new or rebuilt. impeller clearance may not be right. i have access to a 17" flex fan so water pump and fan swap is next steps. i welcome any wisdom and/or input.
