Keffer inc Posted January 24, 2015 Share Posted January 24, 2015 I've installed thermostats in pickups and smaller vehicles, but I want to replace mine on my '99 E7. Definitely looks different, will it be easy to figure how to install or is there any tricks? basicly im asking does it go back exactly how it came out? The big hole through the thermostat is why I question the level of difficulty. Quote Link to comment Share on other sites More sharing options...
wilbur Posted January 24, 2015 Share Posted January 24, 2015 Not hard. You just need a big socket to press the seal in. Quote Link to comment Share on other sites More sharing options...

jakebrake86 Posted January 24, 2015 Share Posted January 24, 2015 ^ What he said. I bought one from Napa once that didn't have a weep hole and I didn't know any better. Talk about a mess. Quote Jake Link to comment Share on other sites More sharing options...

RedBullDog Posted May 14, 2016 Share Posted May 14, 2016 When you replace it, make sure the new one is oriented in the thermostat housing the right way. Also use a good amount of shellac on the gasket. Quote Link to comment Share on other sites More sharing options...
Madmack83 Posted December 29, 2018 Share Posted December 29, 2018 It also says on the themostat face up or forward does that mean the direction the water flows? Quote Link to comment Share on other sites More sharing options...
JoeH Posted December 30, 2018 Share Posted December 30, 2018 I haven't done one on an e7, but I always put the copper heat sink on the "hot" side. It needs to heat up to cause it to open. I also always make sure that there's a small hole in it to allow the water jacket to purge air out of the block before startup. If it doesn't have one, I drill one.

LilMartian Posted January 10, 2019 Share Posted January 10, 2019 Well, for the sake of sounding like the smart ass that I am,sorry, if your working on a 2000 model, that would be an ETech engine and depending on what part of the year it was built, may be a “CCRS”. If her has the uprite thermostat housing, outlet going straight up,takes 1 thermostat and by all means,please put the weep hole to the top, even if you pull old one out and it’s at the bottom or somewhere else. I saw a comment about using scalstic, only if you like digging it out of small fittings and hoses and you do t use the gasket that comes in the new thermostat kit, which, make sure if gasket does cover the check valve(hope it’s a Mack brand) cut hole out and put a new oring in there. E-7 (90-97/8) is done same way. Just thought I would chunk my two cents in the pot!!!! Quote And you thought only NASA had rocket scientist!!!!
