Re: Neon 1998 2000cc SOHC [under the Chrysler name here in the UK]

Hi guys -

my local dealer claims that re-torquing the head bolts after driving with a
new gasket is not necessary - he says that these cars use a different
system, with "sprung bolts" or some such thing. Do you have any idea what he
is talking about, and should the bolts be re-torqued?

many thanks.

Brian

Dealer is right do not re torque or you will have head gasket problems.
when the bolts are installed and torqued they stretch that is how they work.
that is why you should have new bolts bolts listed on your invoice.

True. The bolts are thinner in the middle and they give a little when you
torque them down. The bad part is that you usually can't re-use these bolts
and they can be pricey to replace. No need to re-torque the bolts.

Dealer's correct. They use "Torque-to-yield" bolts which means no
retorquing until the head gasket leaks, which it eventually will. When
your temperature gauge needle pins at "hot", your gasket is leaking. Thank
you for buying a Chrysler product.
