Over heating issues

[richterjustin08]

I have a 98 le, 50th edition.. issues is I pulled a vehicle about an hour away doin 70 nog steady, with no problems... Then I noticed my temp. Gauge starting to climb.. I turned on my heater on but of course it helped bring the temp down.

Things I've done to motor..
- did a complete head job,
-all top end gaskets replaced, and tip end bolts torqued to specs.
- new thermostat
- high perfomance fan clutch from summit
So this is the first time I've drove a good distance out of town in a while... So what are some other ideas of over heating cause?
I have not replaced the radiator by the way, that's the only thing I can think of left.

How many miles on it, have you checked the electric fans to make sure they are working? The radiator may be in need of a good radiator shop cleaning.

Mike we've talked before , the guy I bought motor from , miles unknown, but you have read what I've find to motor so far... And with knowing that who knows when the radiator was flush or cleaned... Of rather just get a new one if that's what you really think is last thing to replace .sir

New ones are real expensive, have your's checked by a radiator shop and if needed rodded out.
