`98 TJ Still Overheating
 

'98 6-cyl Manual

Thanks for all the posts. I've replaced the water pump (with correct
rotation), thermostat (195 F), and radiator cap (18 psi). Still
overheating. So I flushed the radiator per mfg. directions. Replaced
coolant with Preston 50/50. STILL OVERHEATING. However, if I run the
heating at full blast I can keep the gauge out of the RED zone, albeit
still hot. I just ordered a new radiator for $165. Thats the last
thing I know to do.

Re: `98 TJ Still Overheating
 

While you are waiting for the new radiator to arrive you may want to try
using a cooling system 'cleaner' which is a bit stronger than a 'flush' to
get everything possible out of the block and heater core.

Did you ever use 'stop-leak'??

The best way I have found for flushing a cooling system is with the use of a
'flush-n-fill' kit. It is so much more efficient as far as flushing goes
there is really no comparison with the old style 'drain-fill-drain system
because it allows you to force water backwards to its normal flow at a
higher rate.

Prestone (and others) make a complete kit with a selection of tees, clamps,a
radiator spout, and a doglegged .... ahhh.... connect-o-matic thing (female
hose connectors on each end) If you have an old washing machine hose you
can just buy the tee (99 cents) and a couple clamps (99 cents).

You might have been able to have the old one 'rodded out' and chemically
cleaned at a radiator shop but it sounds like your old one was in pretty bad
shape.

Your Jeep came from the factory with the old style "American Green" coolant.
DC says you can still use this but they prefer that you upgrade to the new
G-05 spec which has superior anti-corrosive properties. The only supplier
to the aftermarket is Valvoline's Zerex G-05 brand in the gold jug.

Also please be aware that NOTHING made by Prestone or Peak (or most generic
brands) meets either the new or old spec as all their products are DexCool
or based on DexCool technology and DC specifically warns you against its
use.

If you want to stay with "American Green' it is available from Valvoline
Zerex brand in the white jug.

Finally I recommend that 50/50 premix never be used as there is always
residual water in the block and 50% + 0% i always less than 50% and
concentrations of less than 44% have no appreciable anti-corrosive effect.

The best procedure is to add the concentrate first and then top off with the
appropriate amount of DISTILLED water, that way you know the final
concentration will be.

Note: I am aware that Prestone claims on its label that you can use it in
ANY vehicle. DC, Ford, Mercedes (who all use G-05), Toyota, and Honda (who
have their own spec) say otherwise.

Great info- Thanks! In fact, I did use "stop-a-leak" or "liquid weld"
or some other brand last week during my first drain and fill. This had
nothing to do with the original overheating problem. Are these products
bad for an engine? Would the flushing I did remove all the liquid weld?

Re: `98 TJ Still Overheating
 

The problem with stop-leak products is that they don't know when to stop so
they try to plug everything including the water passages.

If you must try something the safest thing I have used is the powdered
aluminum or brass stuff, you add a bit at a time until the leak stops.

I'm serious about the Prestone.... DexCool will damage your cooling
system....
