A few questions! Looking For help!
Well let me start off with I have a 7.3L IDI 1990.
A few questions:
1. Steps to replace a heater core? And location
2. Do these trucks have OBD ports?
3. When Im driving up hill I get a smell of burned coolant.
4. How can I check compression of the cylinders?
5. What components run the A/C? Which ones are highly to leak?
6. ABS? Worth fixing on these trucks? Cause my ABS light is always on.
I know a ton of questions but I need to fix my truck up. Winter is coming and I'm gonna be doing a lot of hauling and need everything at its best. Please help!

COMPRESSION ; you need a compression tester for diesels gauge that goes to around 1000
PSI and the right adapters for your engine .
COOLANT ; does it smell like it is coming from the inside or the outside ? outside you could have a leak on the exhaust manifold , inside your drain hole could be blocked

there is a oBd on my truck because it is a auto trans the only thing that this obd port could show you is the trans controller if you have a automatic if yours is manual i dont think it would have one it is located under the fuse box it looks like a weird computer connecter you need a scanner to read it you would need a OBD 1 scanner sell them at auto zone
