Overheating Ford Explorer
1998 Ford Explorer 2 door 4.0L SOHV
From a cold start, drive it about 10 minutes
and the temp guage goes to max. No steam or white exhaust.
Can't see any leakage anywhere.
Checked the coolant yesterday and couldn't see any in the
radiator and the reservoir was dry. Topped off both.
Today, same problem. Drove it 2 miles and temp guage goes to max.
I'm thinking it needs a thermostat.
I can buy a thermostat and put it in myself for under $20.
Or I can take it to a shop and they can do it for $65.
Last time I did one a bolt broke off and I had to extract it.
I'm wondering how hard this one is to change.
Here is the diagram from the AutoZone website
and it doesn't look anything like what I have.
Mine looks closer to this diagram for a 3 liter engine.
But even that diagram isn't exactly like what I see under the hood.
So how hard is it gonna be to change this myself.
How can I avoid breaking a bolt off in the block.
Thanks for any help you can give me.
