2005 toyota tacoma 2.7

Asked by toyotasr586 Nov 01, 2020 at 09:35 AM about the 2005 Toyota Tacoma

Question type: Maintenance & Repair

I have no circulation to heater core unless revved
above 2000 rpms. Truck doesnt overheat and
building pressure in coolant system. Cannot figure
what is causing this. Suspecting blown head
gasket but that would not restrict flow to the
heater core would it?

The heater core itself could be clogged. Since the engine is not overheating that's my first suspect. Hope that helps! Jim
