Replace thermostat
 

'98 Cherokee 6-cyl. 112k miles

Two repair garages have told me they don't like to replace the thermostat
unless it's absolutely necessary because the bolts holding the housing tend
to break easily. Temp is varying a bit now and sticks about 20degrees
cooler at times.....I'd like to replace the thermostat before leaving on a
long driving trip next week. Radiator, hoses and water pump have recently
been replaced.

Anyone with experience on this issue have any thoughts about ways to
minimize the chance of breaking these bolts?

Thank you,

I don't see a problem, The head is case iron, so you not looking at
a possible electrolysis. I would put a little silicone on the treads to
prevent corrosion from seizing the bolts for the next guy, very
important to do to the water pump bolts as your shop obviously found
out.

Re: Replace thermostat
 

Any shop that claims not to want to do the t-stat is only looking for more
$$ from you... It is the cheapest and most often the first step in trouble
shooting the cooling system, I changed the t-stat on my XJ about 2 months
ago. The last time it was changed was when I bought it 5 years and 160,000
km's ago. The bolts came out with no problems.

Even if the bolts break, it would be worth doing it now, while you can make
time for it, than to have to deal with it when (and where) the thermostat
fails.
Changing the T-stat is the first thing I do with any cooling system proble.
I use anti-sieze on the bolts and gaska-seal on the gasket, silicon sealant
produces acetic acid, which can cause corrosion, so i only use it where the
surfaces are no longer smooth.
