I posted a thread before about this but I'm gonna start over again, hopefully you guys can help me.
Short story long. I blew a radiator a few months ago, replaced it, few weeks later blew again. After over a week and countless beer I changed the thermostat, water pump, radiator again, fan clutch, refilled with fresh antifreeze. I spent 30 minutes bleeding the air, did this twice, I even rented a pressure test kit and tested the system and radiator cap, everything seemed good.
After 2 days it started to blow the reservoir cap again, it won't overheat, it just blows the cap even when the truck is not up to temperature. It's building so much pressure the reservoir gets full with antifreeze and bubbles.
I don't know what to do anymore, no coolant in the oil or vise versa. I'm hoping new thermostat failed but I'm still getting hot air out of the vents. I'm thinking about removing the thermostat and drive it for a few days to see if it does it again, if it does then I have bigger problems.
I've heard about exhaust pressure going into the cooling system, I'm not sure exactly what that means but I kinda get the point. I haven't done a test for that yet but I guess that will be the next thing to try.
Water pump and thermostat are duralast brand from AutoZone, have lifetime warranty, used Prestone antifreeze, mixed it 50/50.
It's a 98 ranger 4wd 3.0 manual, I don't like driving a baby blue Silverado but that's what I have to drive and I'm glad I put a new transmission in it. I want the little ranger to run without blowing anything up, anybody has suggestions??? Thanks a lot guys..
