1988 Isuzu Trooper - Episode 3: Crusty Cooling System

Our 1988 Isuzu Trooper has some pretty nasty crusty water in the radiator...so that alone warrants a cooling system flush. How bad can it be? Tune in as we tune up our Pooper Trooper's cooling system. #coolantflush #isuzu #carrepair

One hell of a great truck.

I just went from coupes and convertibles to 4X4 as well. I have a 1994 Grand Cherokee now.

[@autoobsessivegarage]

That a sweet vintage! These older trucks really are a blast and a hell of a deal right now.

[@mick5740]

Sweet. I need to do same. Crusty res tank and I want to put a new coolant temp sensor Where is that sensor ?

[@mick5740]

Have you done the little cooling hoses underneath the a tech four-cylinder seem very difficult to replace

[@autoobsessivegarage]

I had to replace one of the heater core hoses that spring a leak…it was a little rough to access. Some of the hoses can be a bit of a challenge to get to.

[@mick5740]

@@autoobsessivegarage yes. Trying ti figure out how the heck to replace the one off the thermostat housing. Spring a big leak can’t drive it. And replacing it seems impossible without taking apart the in take iv also heard things about semi deleting them or routing them different. Very confusing and frustrating in this nice small engine and no room to work Any advice appreciated. I attempted other day with wheel off and threw finder but man it doesn’t seem to be possible yet others say it is

Put that stuff into a glass of water and let it sit and it will turn dark just from adding water. Gimmick to make you think it’s working ….

[@autoobsessivegarage]

I used some cheaper flush before and this stuff loosed up more material. When I disconnected the lower rad there was some significant material in there. No doubt the color change is more for effect, but the product really helped.
