Mosin Posted December 18, 2008 Report Share Posted December 18, 2008 We have a 99 Ford Ranger with a 3.0 V6, 5-Speed man. The problem I have is it started pushing most of the coolant into the over-flow tank and out into the engine bay. At first we thought it was the thermostat. We pulled the theremostat out and it was corroded and it was stuck either open or closed. That didn't fix the over-flow problem. The coolant is at normal levels we don't over fill it. What else could be the problem? It only sprays out of the over flow tank at speeds above 55MPH or at around 3-4000 RPM... Could it be a overly corroded water pump and requires changing? Thanks for any help. Quote Derp. Link to comment Share on other sites More sharing options...
now534 Posted December 18, 2008 Report Share Posted December 18, 2008 sounds to me like the water pump needs changed. does it get really hot fairly quick on the temp gauge? when my water pump went out on my 2.3L the gauge went to the red line almost on the temp gauge. needless to say i took it home and parked it for the day. also is your heater box clogged? theres a tutorial on how to unclog that on rangerpowersports.com/forum the website is down at the moment for a database error but should be running fairly soon i hope.

badasschevy Posted December 20, 2008 Report Share Posted December 20, 2008 (edited) it could be your water pump. also was wondering about what type of fan it has. mechanical clutch fan,or is it electric? the fan could be going out, or if electric a bad relay.

now534 Posted December 20, 2008 Report Share Posted December 20, 2008 the 3.0 should have a clutch driven fan on rangers you could only get electric if you took it out of a taurus or aftermarket. Quote Link to comment Share on other sites More sharing options...
