overheating

You can get them at Princess Auto (around $14-$20 depending on what sale is on). It's illuminated (so if you want that feature you'll have to wire it in) with a little button that lets you choose the colour of the light. It's very simple to hook up, just add a T to the boost pressure line going to the injector pump and hook in the gauge. If you want to route the hose under the carpet and up to the dash you'll need a longer one than what it comes with, but it'll reach the dash if you just want to use it temporarily.

This past long weekend I had a trip from Vancouver to Princeton and further. Driving uphill to the Hope slide at a speed of 55-60 km/h @ 2500 rpm I noticed that the temperature gauge is going up faster that usually and it went from 1/4 to 3/4 of the scale in less than 3 minutes. I was a few hundred meters away from the top of the hill but had to pull over and idle for almost 15 minutes to cool the engine down.[quote][/quote]

After recoring my rad and replacing my thermostat I had the same overheating problems. All three times were climbing hills but at radically different ambient temperatures. The common link was 3000+RPM. The thermostat passed the temperature test at 180 deg and fully open at 195 deg F.

I measured the thermostat opening in the block and found when the thermostat opened the disc restricted water flow at higher RPMs. Initially I altered the disc size and lowered the high RPM temperature. I removed the disc/spring entirely and never had an overheating problem again at any RPM anywhere. I would recommend a thermostat of this design to avoid this problem.

Thanks Wayne for a follow-up. I resolved the issue leaving my Delica with Glen in CC Autos for a week in August. Recored rad, new thermostat, a rad cap and new hoses made the difference. The temp gauge needle stays at 9 o'clock no matter what. The EGT gauge helps me to use the 'gas' pedal appropriately.

I emailed Stant Thermostats about my concerns. They replied to use a Stant 13398 thermostat, available everywhere and even cheaper. That should solve any thermostat problems.
