Hi all, so I had my car out this morning in the hot central Ohio weather(85-90 ish, very humid), and by the time I got home, the gauge just barely passed 220F-probably 225 or 230. I have noticed the car running hotter than usual this summer. I replaced my alternator/belt this year, and experienced a bit of belt slip above 4k RPM for a bit. Tightened the belt, and it has gone away. I have been pushing close to 220F for the last 2 months or so. It has been unseasonably hot and humid here. I have a new radiator in the car, fans are kicking on around 180 or so-they appear to function properly. I did a fuel delivery rebuild and o-ring replacement at the intake manifold, but did not do the water pump/thermostat. Here are WP images; I have never seen any leaks at the seal. What are your guesses as to cause, as well as suggestions for possible fixes? I have taken the WP housing off of another D, but it was done when the intake manifold was already off. Can I replace the WP and thermostat without removing the top end/intake portion of the motor? I'm not trying to be lazy, but if so, that's something I could do in an afternoon, and continue driving the car through the season, rather than wait til the winter and do a bigger teardown. Thanks for any advice!
