1987 nissan pick up cooling problem NEED HELP!!!!!!

[kevinjack]

hello i have a 1987 Nissan pick up with a z24i 4 cylinder inline motor. 2 months ago i noticed it was leaking antifreeze so looking around the engine i noticed there was a wet spot around the temperature gasket so i replaced the gasket thinking that was the problem well i noticed it started to leaking again so im thinking the truck is 22 years old its got to be the water pump. i replaced the water pump today and noticed that it was still leaking so when i had the car on i looked and it was coming out of a 90 degree angle thing going to the thermo wax which is under the carb and the thermostat is before it so i dont know how to fix it if there is even a part to fix it with... i have the service manual for it but doesnt say anything about it.. i hope it dont have to replace the whole intake manifold...can anyone help

this sounds like a head gasket issue which is common on these trucks. Not a terribly hard fix other than alot of stuff to move around under the hood, removing the intake manifold and dealing with the timing chain can be a challenge.........you may want to look at doing a reconditioned head exchange. Taking the old one off and having it milled can be a fix but if your truck has alot of miles like mine ( about 300k ) you can get a rebuilt head with cam, valves ground and seated, and new seals for about $ 275. ready to bolt on and you just have to adjust the valves and torque the head. My truck was in storage for about 10 years and last year I dragged it out and started restoring it and this was the 1st thing that I had to do other than replace one of the ignition coils...............

where is it leaking again?

under the cab from the engine? or is it coming from actually under the dashboard?

I dont understand.

If it is coming from the dashboard its the heater core

you can bypass it with a 20c plastic plug if so

I may have jumped the gun on the head gasket issue. I read the tag as a cooling problem so I re read your problem. Is the truck overheating ? Where is it leaking ? there is a 1 " short rubber hose that is under the intake manifold that is really tough to get to and to see. This is a common hose leak for older trucks due to not being able to get to the location..........replacement is awkward but do-able with a little bit of coaxing.........

yes, I read this as "a wet spot around the thermostat" but you actually wrote around the temperature gasket.
