I have a 1990 jeep Cherokee lerado that has the full tank up by the fire wall. It was getting hot on me all the time very easy. So I put a new thermostat in it and filled it up and let the thermostat

Question type: Maintenance & Repair

Open and made sure it's full. But
now if I take off down the road and
get about 20 miles it starts rising
above 210 I have dual fans ones the
manual and the other is electric and
both work perfectly. My question is
that there's a brass valve looking
thing on to of the fill jug and I'm not
sure what it's for. And people have
also told me to poke a small hole int
the top of the fill tank cap. Can any
one help. Lol

Sounds like you have a low flow in the radiator. Have you had it tested?


Radiator is new


This may sound dumb but did you check the fans to make sure they are drawing air properly? Pushing air or pulling air depending on where you have them mounted.
