Our nissan frontier went hot, we replaced the radiator with a new one, but right noe its sending pressure to the reserve, if i start it without the cap it sends presure up but if i put on the cap it sends pressure to the reserve. can you help us fix this problem?

Welcome to the group!

What does the heat gauge say? Have you tried a new cap? While in Park have someone rev up the engine in short bursts and look to see if the lower hose colapses. Was the thermistat replaced? Was the cooling system air bled when it was refilled? Even in a warm climate youshold be using a 50 - 50 mix of antifreeze and distilled water?

It some times helps to know what Year and model Frontier you are having trouble with and the running gear as well as the the mileage!

Good Luck.. Don S..

the sistem was bled and the whole radiator, inluding the cap, is a new one. It is a 2004 4wd nissan frontier, V6. when we had the problem (before replacing the radiator) even the listers made noise and they discharged. we appreciate any help

also, some people tell us that the engine joint is damaged and needs replacement, however, it is not sending oil to the radiator or water to the engine, or water to the muffler, which we think are the most common signals of a joint problem... two radiators caps were replaced, if you know any different way of bleeding the sistem, perhaps reviewing with us the process can help? thanks

I'm confused!!!! It sounds like a head gasket problem. There is a coolant bleed bolt on top of the intake plenum.
