View Full Version : Engine temp varies

08-05-2013, 11:24 PM
I've got a 2007 X-15, 350 engine overheated (alarm) when circulating pump seized. Pump was replaced. Impeller was fine but replaced anyway. Then original J hose burst and hose connectors to exhaust manifolds melted off. All is replaced and appears to be working fine except temp gauge. Multiple 160 degree thermostats have been placed but temp gauge continues to vary between 190 and 160. From reading these threads I've come to realize that this year and model had overheating issues. Mechanic is concerned about the temp gauge varying between 190 and 160. Any thoughts? Thx in advance.
Exhaust boots were removed and checked, no de-laminating.
